Best CPAP Pillows for Side Sleepers of 2026

If a full-face mask has ever been bulldozed sideways by foam, this is the pillow to try first. Its side cutouts are the largest of anything in this group, scooped deep on both flanks so the cushion sits in open space instead of being pressed back at your cheek.

Softer foam is the second half of that idea, and it is the part we appreciated most. Where the Lunderg holds you up firmly, this one gives a little, which lets a full-face mask settle instead of perch. Nothing about it feels under-filled; the butterfly shaping still puts a supportive edge behind the neck. But it is the plushest surface among the picks here, and lighter sleepers tend to do better with that give.

The 2 cm insert is the adjustment: leave it in for height, pull it for less, and expect a night or two to decide. The cover snaps at the corners so it doesn't slide, washes in the machine, and has an ear hole that keeps pressure off the side of your head. At 24.8 by 13.8 inches it is long rather than wide, which suits a pillow you stay fairly centered on.

The Lunderg gives you one removable layer. This IKSTAR gives you a dual-height contour plus a 2 cm insert, and for a broad-shouldered side sleeper that difference is the whole purchase. A pillow that sits too low drops your head below your spine and lets the mask close against the mattress.

It is built tall, with a scooped center and raised side wings that stop your shoulder pushing the pillow out from under you. The cooling cover is machine washable and the ear recess gives the side of your head somewhere to sit, a detail we noticed on the third night rather than the first, once we stopped waking with a sore ear.

What settles it for us is the tuning range. Two contour heights before you touch the insert mean you fine-tune instead of choosing between high and higher, and the foam rebounds slowly enough that a night's pressure does not leave a trench. If you have been folding a towel under your pillow to get the height right, this is the pillow that replaces the towel.

The notches on this pillow sit at the two ends rather than wrapping the corners, and that placement decides whether it works for you. If your mask sits forward on your face, the recess is exactly where the cushion lands. If your headgear puts the cushion back toward your ear, you are lying on solid foam and the cutout is decoration.

Two heights in one pillow is what we liked most. One side measures 4.33 inches, the other 3.54, so flipping the pillow is the entire adjustment, with no inserts to lose and no layers to store. The scooped center cradles the back of the head, which kept the seal intact when we rolled from side to back in the night, and at 3.5 pounds the pillow stays where you put it.

At 25.59 by 15.75 inches it is one of the roomier pillows here, and that matters if you turn often. The cover comes off for the machine, and the foam is both CertiPUR-US certified and Oeko-Tex approved. We noticed no odor out of the box, which is not a given with memory foam that has been compressed in a carton.

Two inserts, one softer and one firmer, plus a base spacer that drops the whole pillow by 0.8 inch: this is the most adjustable pillow in the group, and it is why we recommend it to anyone buying a first CPAP pillow without knowing what they need.

The four resulting heights cover the range where most side sleepers land, and swapping the insert changes the feel more than you might expect. The firmer one borders on rigid; the softer one gives enough that a nasal mask settles into the cutout instead of sitting on top of it. The 16.3-inch width is the widest in this set, so your shoulder has somewhere to go when you roll.

The caveat is the shape. There is a pronounced cervical roll behind the neck, and it takes a week or two before it stops feeling like a foreign object, worth knowing if you have reacted badly to contoured pillows before. The cover is a cool-touch nylon-spandex blend that washes easily, and the foam core is spot-clean only, so a spill stays on the cover or becomes your problem.

The least expensive pillow in this group is also one of the lightest at 2.7 pounds, and for a first CPAP pillow that combination is hard to argue with. Nothing about it reads as cut-rate: the foam is CertiPUR-US certified, the cover is a cooling nylon-spandex blend, and both sides have cutouts.

Two heights, 3.5 and 4.33 inches, give you a low side for back sleeping and a higher one for your side. At 25.6 by 15.8 inches it is a full-size pillow with room to roll, and the cupped head area matters more than we expected, keeping your head from drifting toward the edge of the cutout where leaks usually start.

Loft is where it gives ground. Under a heavy head this is the pick most likely to feel thin, and if you are broad across the shoulders you will want more height than it offers. For a smaller sleeper, a back-and-side mix, or someone who wants to find out whether a cutout design helps without spending much, hand this one over the premium pillows.

This is the longest-running design in the group, and the shape it settled on is unusual: two corner gaps instead of full side cutouts, a 5.12-inch height, and a face just 11.81 inches wide.

The corner gaps do a job the side cutouts cannot. Sitting at the bottom corners, they give the hose somewhere to run and keep straps out of the foam when you are square on your side. The difference showed up most with a nasal-pillow mask, where tubing tug rather than cushion pressure was what broke the seal.

Just over five inches is a lot of pillow. It suits a broad frame and a firm mattress and can feel like too much if you are small or sleeping on something soft. The removable foam pad is a layer rather than a second contour, so it lowers the height without changing the shape underneath.

Where we land is that this is a pillow for a specific sleeper: broad shoulders, a tall setup, and a hose that keeps tugging. If two of those three do not describe you, one of the wider, lower picks here will be easier to live with.
