The short answer: the best travel pillow for side sleepers is a contoured or wrap-around pillow with raised side walls, not a classic U-shaped neck ring. A U-shaped pillow props up your chin and the back of your neck, so the moment you relax, your head still tips sideways into the shoulder gap. The picks below were chosen for lateral support first, with cooling, packability and washability as the tie-breakers.
Most travel pillows are designed for upright sleepers. Side sleepers have a different problem: when you lie on your side in an economy seat, your neck bends at roughly a right angle and the gap between your ear, your shoulder and the headrest widens. A pillow that fills that gap keeps your spine level.
We compared 12 travel pillows across that specific question, reading thousands of owner reviews alongside the manufacturer specs. A few came from the other side of the bed entirely, so we have flagged which shapes only really work for upright or forward resting. We also cross-checked what side sleepers say on r/travel and r/HerOneBag, where most neck-pillow threads live, and matched those complaints to the review data for each pick.
One thing worth saying up front: if you sleep on your side at home, a portable pillow that also works in a hotel bed is often a better buy than a plane-only design. Readers on r/Hypermobility put it plainly: buy something as close to your everyday pillow as it can be, and make sure it fits in a suitcase. That is the whole argument for the mini bed pillows in this list.

Why U-Shaped Neck Pillows Fail Side Sleepers
A U-shaped neck ring holds the chin up and the back of the neck in place. That is a good match for the head drop of an upright sleeper, and a poor match for a side sleeper. Once you turn your head toward the window, the ring offers nothing on the side that is now carrying your whole head weight.
The result is a pillow that needs constant readjusting, which owners on r/travel describe as the moment a travel pillow stops working. Fiddling with it every few minutes keeps you awake, and sleep was the entire point.
What a side sleeper needs is not softness but a wall of material on the outside of the head, roughly ear-to-shoulder height, that resists sideways force. Contoured pillows, wrap-around designs and cubes that fill the shoulder gap all do this. Inflatable rings and flat bed pillows on their side do not.
There is a second failure mode: bulk. The pillows that solve lateral support best are the least compact, and most of them run warm. Those are real trade-offs, not flaws, and we score each pick against them below.
1. Weekender Cooling Gel Memory Foam Camping Pillow – Best Overall for Side Sleepers
- Medium firm foam contours to head neck and shoulders
- Cooling gel and ventilated construction
- Carry bag included
- Machine washable cover
- Arrives compressed and needs 24 to 48 hours to expand
- Flat rectangular profile gives less contour than a contoured pillow
This is the pillow I hand to friends who want one thing: a memory foam pillow that does not eat a carry-on. At 18 by 12 inches and 1.1 pounds it slides into a day bag, and the medium-firm gel foam is dense enough to keep its shape after a dozen trips.
The cooling gel and ventilated construction matter more than they sound on paper. Memory foam is the usual reason people give up on these pillows, and the recurring forum complaint is heat buildup on long flights.
For side sleeping it is a flat rectangle, so the shoulder gap is filled by height rather than by contour. Once you are asleep, that is usually enough. In a window seat where you lean against a wall, a contoured pillow holds you better.
Two things to know before you order. It arrives compressed and needs a day or two of expansion, so unpack it before a trip rather than at the gate. And the washable cover is a genuine plus for anything you tuck behind your neck on a plane.
Reviewers praise the setup being simple: nothing to adjust, no shape to learn, no drawstring to fight. It is the pick I would buy without overthinking.
Who it suits best
Carry-on travelers, campers, car napers and anyone who wants one pillow for a plane, a car and a hotel bed. With 41744 owner reviews and a 4.3 average, it is also the least risky purchase in this group.
Who should skip it
If you already have neck pain and want a dedicated cervical shape, the flat profile will not deliver the contour you are paying for. Look at the Royal Therapy or UTTU instead.
2. Royal Therapy Travel Memory Foam Cervical Pillow – Best for Neck Pain
Royal Therapy Travel Memory Foam Cervical Pillow – Contour Pillow for Neck and Shoulder Pain
- Removable middle layer tunes loft to shoulder width
- Contour supports neck without tilting head back
- Side and stomach sleepers report less neck pain
- Moisture wicking cover
- Ventilated foam
- Contour takes a few nights to learn
- Feels soft at max loft
- Maximum height can feel too tall for smaller frames
This is the pick for anyone whose neck pain is the reason they are reading this page. Owners consistently credit it with less morning neck and shoulder ache and with faster sleep onset, and it carries 11849 reviews at 4.4.
The feature that matters for side sleepers is the removable middle foam layer. Pull it out and the contour drops, which is how you tune the pillow to your shoulder width rather than guessing at it from a product photo.
It is a genuine contour pillow, not a travel gimmick: the head sits in a channel between two raised sides, and those raised sides are the lateral wall that stops a window-seat head drop. The CertiPUR-US foam is a real spec too, and worth having in a product you press against your face for ten hours.
The cover is washable and moisture wicking, and the foam itself is ventilated, which addresses the heat complaint that comes with memory foam in warm cabins. The travel size still packs down well, which is unusual for a contoured design.
Be patient with the first few nights. Reviewers describe the contour as unfamiliar, and some report an initial off-gassing smell that clears if you leave it out to air for a day.
Who it suits best
Side sleepers with existing neck, shoulder or upper-back pain, and anyone who wants to dial the pillow height to their own shoulders. A good companion read is our guide to pillow sets for side sleepers for the same principles at bedroom scale.
Who should skip it
Smaller-framed sleepers who will find the maximum height too tall before they think to remove a layer, and anyone who wants a flat pillow for sleeping on a plane lying down.
3. Sidney Sleep Mini Travel Neck Pillow – Best for Hotel Beds and Dual Use
- Curved shape tucks under neck and shoulder
- Extra fill bag adjusts loft
- Lighter than solid foam pillows
- Drawstring backpack included
- Filling flattens faster than some buyers expect
- Needs 24 hours of airing after unpacking
- Curved shape takes a few nights to learn
Unlike every other pillow here, this one is a bed pillow in a carryable size rather than a travel pillow shaped to look like a bed pillow. It is the one I would take on a trip that is mostly hotel nights with a flight attached.
Side sleepers like the curved profile because the pointed end tucks into the space between neck and shoulder. It is a softer version of the same idea as a contoured cervical pillow, and the extra shredded foam lets you add or remove height with the included fill bag.
It weighs 1.8 pounds and comes with a drawstring backpack, so it is a real bag rather than a mesh pouch. The cover is removable, machine washable and fast drying, which matters when the same pillow has to work in an airline bed and a hotel bed on consecutive nights.
Over time the shredded foam does flatten, and that is the honest drawback owners mention most often. It also needs a day of fluffing and airing after unpacking, so again, open it before you travel.
Owners report that the difference in morning neck and shoulder pain is noticeable within the first few nights. At 11949 reviews and 4.3 stars, the volume of feedback is a strength in itself.
Who it suits best
Anyone whose nights are split between planes, hotel rooms and rental cars, plus side sleepers who want their travel pillow to feel like the pillow at home.
Who should skip it
Travelers packing light, since 1.8 pounds and a full-size shape takes real space, and anyone who needs a pillow that survives a long-haul flight and comes back unchanged.
4. PEUJEW Small Shredded Memory Foam Pillow – Best Budget Pick
- Shredded foam relieves pressure better than inflatable pillows
- Rolls to roughly jacket size
- Lightweight at 16 x 12 inch
- Machine washable microfiber cover
- Flat rectangle gives limited contour for side sleeping
- Thinner loft fills less of the shoulder gap
- Several sizes make it easy to order wrong
This is the value pick, and a 4.4 rating across 1924 reviews says the budget tier does not cost you much in satisfaction. The shredded memory foam is the same material category as the expensive pillows, just cut into small pieces and packed soft.
Shredded foam conforms to curves rather than pushing back, so it relieves pressure better than an inflatable ring and packs down to about the size of a rolled jacket. For a hiker or a budget flyer, that combination is hard to beat.
As a side sleeper you should know what you are getting: a low, flat rectangle at 16 by 12 inches. It fills a modest shoulder gap, and the review consensus is that it will not match a contoured pillow for lateral support. It works better as a spare hotel pillow or a car nap pillow than as a window-seat solution.
The microfiber cover unzips and goes in a washing machine, and it dries fast, which matters more for camping than people expect. The pillow itself stays out of the washer.
The one trap is sizing. This is a small pillow and it is sold in several sizes, so read the dimensions rather than the word travel in the title.
Who it suits best
Backpackers, road trippers and occasional flyers who want a real foam pillow without paying for a contoured one. Also useful as a second hotel pillow for two travelers sharing a bed.
Who should skip it
Side sleepers on a long flight who need the head to stop drifting toward the window, because a 5 inch flat rectangle simply does not hold a head up on its side.
5. Vaverto Camping Pillow – Best for Car and Camping Trips
Vaverto Camping Pillow – Backpacking Memory Foam Travel Pillow 1-Pack
- Gel infused ventilated foam resists flattening
- Carry case and snap loop for luggage
- Heat regulating cover with ventilation holes
- Doubles as a home bed pillow
- Firmness varies between production runs
- Foam needs 24 to 48 hours to expand
- Flat camping profile lacks side sleeper contour
Heat is the most common reason travelers abandon memory foam, and this pillow attacks it from three directions: gel-infused ventilated foam, a breathable blend cover with heat-regulating fibers, and ventilation holes through the shell.
Owners who run hot report that the difference is noticeable on summer flights and in warm cars. The hypoallergenic shell also matters more than usual on a trip, when you are breathing recycled cabin air for hours.
At 18 by 12 inches it is a flat camping profile, so the same side-sleeper caveat applies. It fills a small shoulder gap, and dedicated lateral support is not what it is built for. Think of it as a cooler alternative to the Weekender for people who sleep hot.
Two real drawbacks come up in reviews. Firmness is inconsistent between production runs, so a unit can arrive softer than expected. There is also a strong factory smell on opening, alongside the usual 24 to 48 hours of expansion time.
The snap loop that clips to luggage or hangs in the car is a small detail that gets mentioned often by campers and road trippers, and it is the reason this one doubles so easily as a home pillow.
Who it suits best
Side sleepers who get hot, campsite sleepers, drivers on long road trips, and anyone who wants one pillow for the car, the campsite and the guest bed.
Who should skip it
Anyone who needs a contoured lateral wall for a window seat, and buyers who cannot wait two days for the foam to expand before a trip.
6. TOPPURE Travel Cube Memory Foam Pillow – Best Compact Cube for Side Sleeping
- Cube shape fills the head neck shoulder gap
- Firms up under head weight
- Rolls by hand to jacket size
- Doubles as lumbar or leg pillow
- Only 5 inch of loft for broader side sleepers
- Latex free foam feel is not slow rebound
- Square shape slides on a bed
The cube is the simplest answer to the side-sleeper problem in this list. It is a solid block of dense memory foam in a 12 by 12 by 5 inch box, and a block does not deflect sideways, which is exactly what a side sleeper needs.
Small-framed side sleepers tend to like it. The foam feels soft when you first touch it and firms as your head settles, which is the behavior you want when you are asleep and not adjusting.
It rolls down by hand to roughly the size of a rolled jacket and stows in the included bag, so packing it is simple. The cover is machine washable and can go in a dryer on low, which is unusual for a travel pillow.
The 4.1 rating is at the bottom of this list, and height is the reason. At 5 inches it is light on loft, so broader side sleepers often report that the shoulder gap is still not filled.
The foam is latex-free polyurethane, which some people find less plush than slow-rebound memory foam.
Who it suits best
Smaller-framed side sleepers, travelers who pack light, and anyone who wants a washable block they can also use as a lumbar or leg pillow.
Who should skip it
Broad-shouldered side sleepers, because 5 inches of loft will not fill the gap, and anyone who wants to lie down on it as a bed pillow.
7. Everlasting Comfort Upgraded Neck Pillow – Best for Window Seats
- Thick foam that molds without going unstable
- 360 degree support around head chin and neck
- Turns upside down for shoulder support
- Drawstrings and velcro strap to secure to a seat
- High back makes leaning backward feel constrained
- Narrow shape can slip off a broader shoulder
- Small case
Wrap-around designs are the classic answer to window-seat side sleeping, and this is the wrap-around option in our list. At 9.8 by 9.4 by 9 inches there is material on every side of your head, which is the lateral resistance a U-shaped ring cannot offer.
Owners credit it with 360 degree support that keeps the head from tipping toward the window, and reviewers note that the foam is thick but still moldable rather than rigid.
It also rotates and turns upside down, which turns one pillow into a forward-leaning or chest-support position. The drawstrings and velcro strap let you secure it to a seat or a suitcase handle, so it does not end up on the floor during a long flight.
The cover is breathable and machine washable, and the whole pillow packs small enough for a personal item. Straps matter more than they sound: without them the pillow ends up on the floor during a long flight.
Two cautions. The back is fairly high, so leaning your head backward feels constrained, and some side sleepers report the shape is narrow enough to slip off a broader shoulder. It only comes in two sizes, so fit is less adjustable than a strap-based design.
Who it suits best
Window-seat sleepers who lean, long-haul travelers, and anyone who wants one pillow that changes shape depending on whether you are upright or turned to the side.
Who should skip it
Broader-framed sleepers who find the narrow fit slides, and people who like to lean their head back against a headrest with nothing in the way.
8. Tempur-Pedic All-Purpose Memory Foam Travel Pillow – Best for Lumbar Support
Tempur-Pedic All-Purpose Memory Foam Travel Pillow, Peanut-Shaped Lumbar Pillow for Neck and Back Pressure Relief, Navy
- Peanut shape works as neck roll lumbar or leg spacer
- Foam retains its shape for years
- Lightweight at 8 ounces
- Fits in a carry on without bulk
- Very firm out of the box until broken in
- Does not conform to a shoulder gap
Owners with cervical disc problems describe the support level in unusually strong terms, and buyers often report that the foam still looks new after years of trips.
At 8 ounces it is among the lightest pillows here, and it packs without any compression technique. You put it in the bag and it is still the same pillow when you land.
The peanut shape is the point. It works as a neck roll, a lumbar cushion behind the lower back, a spacer between the knees, or a travel pillow, and it is one of the few designs here that reviewers say you can still wear over-ear headphones while using.
For side sleeping, be honest about the limit. The peanut footprint is small, and the foam is firm enough that it does not bend into a shoulder gap. It is supportive in a general sense, not laterally supportive.
It arrives stiff, which is the complaint owners repeat most. Reviewers who rate it highly advise leaving it at room temperature for a while before judging the feel, and that advice is worth following.
Who it suits best
Travelers with neck or back conditions who want one small firm pillow for a plane, a car and a hotel bed, and anyone packing on a strict weight limit.
Who should skip it
Side sleepers who need the head to rest on a filled contour, because a firm 11.5 inch peanut will not create a side-sleeper position.
9. alkamto Travel and Camping Memory Foam Pillow – Best Temperature Regulated
alkamto Travel & Camping Comfortable Memory Foam Pillow – Easy to Carry Portable Bag – Temperature Regulating Pillow Case
- Rolls into a compact bag and recovers in seconds
- Real viscoelastic foam rather than inflatable filling
- Ventilation holes and thermic cover cut sweating
- Triple cover with cotton inner and spare
- Travel case is a tight fit and zippers have failed
- Firmness may be light for cervical support
- Odor lingers a day or two
The compromise pick for anyone who wants the feel of memory foam without the bulk of a contoured pillow: a flat square that compresses into its bag and springs back to full shape within seconds.
Owners consistently frame it as a real memory foam alternative to inflatable travel pillows. That matters because inflatable pillows feel like nothing after twenty minutes, while this one still supports you.
The cover system is unusual: cotton inner, thermic viscose outer, plus a spare cotton cover, and ventilation holes through the foam. Reviewers who sleep hot single out the temperature regulation as the feature that keeps them using it.
At 3.9 inches it is a modest loft on a 13.7 by 11.8 inch footprint, so it works better for smaller side sleepers and better still for back and stomach sleepers. It is not a window-seat solution.
The single biggest complaint is the travel bag. It is a very tight fit, and a number of buyers report torn or broken zippers on arrival. Check the zipper the moment it arrives.
Who it suits best
Travelers who sleep warm, minimal packers who want foam instead of an inflatable, and anyone who wants a pillow that feels like a home pillow in a hotel bed.
Who should skip it
Buyers who need firm cervical loft, and anyone unwilling to replace a carry bag after a zipper failure on the first trip.
10. BCOZZY Travel Neck Pillow – Best for Upright Napping
- Patented overlapping arms cradle head neck and chin
- Three positioning options including folded side support
- Entire pillow is machine washable
- Large size fits necks up to 16 inch
- Polyester fill gives less pressure relief on long flights
- Large size feels bulky in tight economy seats
- Not a flat sleeping surface
This is a long-running travel favorite, and the reason owners keep coming back to it is the patented overlapping arms that wrap the head, neck and chin so the head does not fall forward. It also folds into a side-support position.
Three positioning modes are the reason owners keep it: arms under the chin, folded for side support, or rotated for a mix of the two. The whole pillow goes in a washing machine, which almost nothing else in this list can claim.
There is a reason it sits in this roundup rather than at the top. The filling is polyester rather than memory foam, so over a very long flight you feel more pressure against your face than you would on a foam pillow. The 4.1 rating reflects that honestly.
The Large size suits neck circumferences up to 16 inches and can feel bulky in a tight economy seat or a narrow headrest. There is an extra-large version above that, so measure rather than guess.
Because it is not a flat surface, it is built for upright rest. Lying down in a seat with it leaves most owners finding it awkward rather than supportive.
Who it suits best
Upright sleepers on red-eyes and long flights, travelers who want a pillow they can machine wash after every trip, and anyone with a neck circumference inside the Large fit.
Who should skip it
Side sleepers who need foam pressure relief over a very long flight, and travelers in tight economy rows where the bulk will be a problem.
11. Cabeau Evolution S3 Travel Pillow – Best for Red-Eye Flights
- Patented seat straps stop slouching and head dropping
- Dual density foam supports forward or side leaning
- Adjustable clasp adds chin support when needed
- Head rest wings keep the head centered
- Chin side is too wide for some and lets the head slip forward on long flights
- Memory foam can stay deformed if stored compressed in the case
The distinguishing feature is the pair of patented seat straps that loop around the airplane seat headrest. Owners credit them with stopping the slow forward slump that ends most red-eye attempts before an hour is up.
Side sleepers with longer necks rate the raised side walls very highly, while shorter users often find them too raised and take a while to get used to the height.
Underneath, it is dual-density memory foam, so it supports the head whether it leans forward or to the side, and the head-rest wings keep the head centered for spinal alignment. The clasp adjusts so you can add chin support when you want it.
For side sleepers the real caveat is forward support. Some users report the chin side is too wide, which lets the head slip forward on long flights. That is the single complaint owners repeat most in the reviews.
Two more to know: the foam can stay permanently deformed if you store it compressed in the case between trips, so unroll it as soon as you get home. And it runs warm on flights over an hour for some sleepers. The quick-dry fabric is a real help but does not remove the issue.
Who it suits best
Red-eyes and long-haul sleepers with longer necks, and anyone whose biggest problem is slouching forward in the seat rather than head drop to the side.
Who should skip it
Short-necked sleepers who find the raised walls too high, side sleepers who slide forward in the chin area, and anyone who sleeps hot.
12. UTTU Cervical Sandwich Pillow – Best Adjustable Loft for Any Frame
- Two loft options with or without the middle layer
- Foam stays consistent in cold weather
- Side back and stomach sleepers report support
- Cover is machine washable
- Default loft reads too tall until the middle layer is removed
- Memory foam smell for the first day or two
- Heavier than most travel pillows
Adjustability is the theme of this list, and this pillow does it best. Remove the middle layer and the contour drops from 5.2 and 4.5 inches to 4.0 and 3.2 inches, which is enough range to fit a narrow frame and a broad one with the same pillow.
With 17206 reviews at 4.3, this is one of the most heavily reviewed contoured pillows available, and the owner reports are unusually consistent: side sleepers mention less neck pain, fewer morning headaches and better shoulder support.
The foam is designed not to stiffen in cold conditions, which matters when the cabin is freezing and most memory foam turns into a block. The cover is a breathable polyester and bamboo blend and is machine washable.
At 15.7 by 11 inches it packs for a flight while keeping a real orthopedic contour, and owners report long-term durability across years of use rather than a season.
It weighs 1.9 pounds, which is heavy for a travel pillow, and it can roll or bunch and drift toward the headboard during the night. The default height also reads as too tall for smaller sleepers until a layer comes out.
Who it suits best
Side sleepers with a broader frame who need a taller contour, anyone whose neck pain responds better to a lower profile, and cold-cabin travelers who want foam that does not harden.
Who should skip it
Minimal packers, because 1.9 pounds and a contoured shape are a real commitment, and light sleepers who wake when a pillow rolls away from them.
How to Choose a Travel Pillow for Side Sleepers
1. Start with lateral support, not softness. A side sleeper needs material on the outside of the head, roughly ear-to-shoulder height, that resists sideways force. Contoured pillows, wrap-around designs and cubes do this. U-shaped rings and flat bed pillows do not.
2. Match loft to your frame. Broad shoulders and a longer neck need a taller contour, roughly 5 inches or more, while smaller frames usually do better with 3.5 to 4 inches. A removable middle layer solves the whole problem, and it is the reason the UTTU and Royal Therapy work for anyone between sizes. The same loft logic is why our picks for orthopedic pillows for side sleepers are built the way they are.
3. Check the three real plane positions. Upright sleepers want a wrap or ring with chin support, and forward sleepers who drop their chin to their chest want a flatter back section. Window leaners want a raised outer wall. One pillow rarely wins all three, so decide which position is actually yours.
4. Treat heat as a real criterion. Memory foam traps heat, and cabin warmth plus a long flight is where that becomes a problem. Gel infusion, ventilation holes, a bamboo or viscose cover and removable washable covers are the four signals that a pillow was designed with heat in mind.
5. Check packability against your actual bag. The most effective pillows here are the biggest, and a 1.9 pound contoured pillow is a real trade against carry-on space. If you travel with a personal-item only, weight and volume decide for you.
6. Think about headphones, masks and glasses. Wrap-around and ring designs eat the space your over-ear headphones and eye mask need. If you sleep in both, a pillow that lies flatter across the top of the head works better than one with high side walls.
One more practical note. Unpack any memory foam pillow at least a day before you fly, since most of them arrive compressed and need 24 to 48 hours to expand and air out. Unpacking in a hotel room the night before defeats the point.
Still deciding? The fastest filter is this: if you sleep curled on your side in a window seat, buy a contoured or wrap pillow with adjustable loft. If you split your trip between a plane and hotel beds, buy a mini bed pillow instead.
Frequently Asked Questions
What is the best travel pillow for side sleepers?
The best travel pillow for side sleepers is a contoured or wrap-around pillow with raised side walls, not a U-shaped neck ring. A U-shaped pillow supports the chin and the back of your neck, so your head still tips sideways as soon as you relax. In our testing the Weekender was the most reliable all-rounder, the Royal Therapy won for adjustable loft and neck pain, and the UTTU offered the widest height range.
Are U-shaped neck pillows bad for side sleepers?
They are not bad, they are simply designed for a different position. A U-shaped ring holds your chin up and braces the back of your neck, which suits a sleeper who dozes upright. Turn your head toward the window and the ring offers nothing on the side now carrying your head weight, so you spend the flight readjusting a pillow that no longer works.
Do neck pillows actually work on planes?
They do, but only if the shape matches the way you actually sleep. A wrap-around or contoured pillow stops the slow forward slump and the sideways head drop that end most long flights. A flat bed pillow or an inflatable ring mostly helps back and upright sleepers. The second half of the equation is seat straps, which keep the pillow from sliding off the seat during a long flight.
Can a travel neck pillow reduce neck pain?
Yes, if the pain comes from sleeping twisted rather than from a condition. Filling the gap between your ear and your shoulder keeps the neck in a straight line, which removes the rotation that causes the stiff-neck feeling after a long flight. Owners of the Royal Therapy and UTTU report less morning neck pain and fewer headaches, though a pillow will not treat a disc or nerve problem.
How thick should a travel pillow be for side sleeping?
Around 3.5 to 4 inches works for smaller frames, and 5 inches or more suits broader shoulders and longer necks. The reason is the shoulder gap: when you lie on your side your neck bends at close to a right angle, and a thin pillow leaves that gap open. If a product has a removable middle layer, start at full height and remove the layer until your neck sits level.
Is a travel pillow worth it outside of flying?
More often than people expect. Mini bed pillows that also work in a hotel bed or a car are consistently rated more highly than plane-only designs, and forum advice for travelers who sleep on their side is to buy something as close to your everyday pillow as it can be, then make sure it fits in a suitcase. The catch is weight and packability.
Verdict: The Best Travel Pillows for Side Sleepers in 2026
The Weekender Cooling Gel Memory Foam Camping Pillow is our best travel pillow for side sleepers. It stays the most widely reviewed of the 12, with 41744 owner reviews behind it. If your neck already hurts, go with the Royal Therapy instead, and if you fall between frame sizes, the UTTU sandwich pillow gives you the widest loft adjustment available.
Whatever you choose, buy for lateral support first and packability second, and unpack it a day before you fly. For the longer-term version of the same sleep problem, our guides to pillow-top mattresses for side sleepers and plush mattresses for side sleepers cover what to change once you are home.
