The Coop Home Goods Eden is the most customizable CPAP pillow you can buy for side sleeping. It comes with a zippered compartment and a bag of extra microfiber/gel memory foam fill so you can dial in the exact loft you need—anywhere from a thin 3 inches up to a dense 6 inches. The ergonomic cutout on the side is shaped like a rounded trapezoid, which gives a full-face mask plenty of clearance while still cradling the jawline. The fill blend of gel-infused memory foam and microfiber keeps the surface feeling cool even after hours of side pressure.

The Lulltra cover is buttery soft and machine washable, and the gusseted 2-inch edge prevents the fill from shifting into a lump under your ear. The CertiPUR-US and GREENGUARD Gold certifications mean no chemical off-gassing, which is a real concern for people with breathing sensitivities. Side sleepers who swap between their left and right side will appreciate that the cutout works on both edges of the pillow equally.

The main trade-off is price: this is the most expensive option on this list. You are paying for the precision engineering and the ability to completely control the pillow’s height. If you have ever struggled with a pillow being a quarter-inch too tall or too short, this model eliminates that frustration entirely.

If memory foam feels too dense or hot for your sleep style, the Lunderg Parkin offers a down-alternative fill that is plush yet supportive. The adjustable fill system uses a zippered cotton cover, letting you remove or add clusters of the down-alternative material to change the loft. For side sleepers who prefer a softer feel under the cheekbone, this pillow absorbs pressure without bouncing back too quickly. The 100% cotton case breathes well and reduces sweat buildup overnight.

The cutout design on the side is generous enough to accommodate nasal pillows and smaller full-face masks. Because the fill is loose, the pillow does not have a rigid cutout shape that can collapse—it simply compresses around the mask naturally. This makes it a strong choice for people who change mask styles frequently or are still dialing in their equipment. The cotton cover also unzips completely for machine washing, which is important for CPAP users who want to keep allergens and dust mites out.

One limitation is that the loft adjustment is less precise than a foam insert system. Removing a handful of fill can change the height by a full inch, and it takes some trial and error to get it balanced.

Lunderg’s memory foam CPAP pillow combines an adjustable foam core with a clever packaging bonus: you get two machine-washable pillowcases in the box. The memory foam itself is medium-density and slow-rebound, which means it conforms around the mask instead of pushing against it. The cutout runs along the entire side edge, creating a channel that works well for both nasal and full-face masks. The included height adjuster insert (roughly a 1-inch shim) lets you toggle between a lower loft for back sleeping and a higher one for side sleeping.

The dual-pillowcase approach is practical for CPAP users who rotate masks or want a quick swap without laundry. One case is a standard bamboo-rayon blend, and the other is a cooler-feel polyester—neither traps heat badly, though the polyester runs slightly cooler. The foam itself does not have gel infusion, so it sleeps warmer than the Coop Eden material, but the removable cases help dissipate some heat overnight.

The main drawback is that the memory foam has a strong off-gassing smell that can last up to 48 hours. Air it out for a day before using it. The foam also lacks a cooling top layer, so hot sleepers may want to pair it with the cool-feel pillowcase option from the box.

This Elviros model is designed for side sleepers who also suffer from neck stiffness. It uses an ergonomic contour shape with a central hollow that cradles the head, while the sides rise higher to fill the shoulder gap. The cutouts for the CPAP mask are integrated into those raised side wings, allowing the mask frame to sit in a recessed pocket without pushing against the foam. The pillow features two distinct height zones: one at 4.92 inches and a second at 5.12 inches, which you access by rotating the pillow 180 degrees.

The high-density memory foam is CertiPUR-US certified and slow-rebounds at a rate that prevents the head from bottoming out. The cover is a breathable polyester-cotton blend that removes for washing. The dual-zone adjustability is especially useful for side sleepers who sometimes shift to their back during the night—you get a lower loft for back sleeping on one side and a higher one for side sleeping on the other.

The main weakness is that the cutout pockets are relatively narrow. Users with large full-face masks (like the ResMed F20 with a wide frame) may find the mask frame pressing against the outer edge of the pocket. It works best with nasal masks and smaller full-face options.

The second Elviros entry on this list is more purpose-built for CPAP than the cervical model, with four adjustable height options via two removable inserts. The pillow comes with a base foam core and two shims (one 0.78-inch and one that can be combined for a total of four possible loft heights ranging from 4.14 to 5.12 inches). This range covers the needs of most side sleepers. The cutouts on both sides are wide enough for nasal pillows and many full-face masks, and the medium-firm density holds the cutout shape well under a 150-180 pound head load.

One key differentiator is that this pillow is FSA/HSA eligible, which is a practical advantage if you have a flexible spending account. The memory foam itself is CertiPUR-US certified, and the upgraded insert has less dye and fewer impurities than previous versions. The cover is removable and machine washable, and the fiber surface is advertised as breathable, though it does not feature a dedicated gel cooling layer. The pillow measures 23.6 inches by 16.14 inches, which is slightly larger than a standard queen pillow and gives a bit more real estate for moving around.

Potential buyers should note that the base foam is fairly firm. Side sleepers who prefer a plush sink-in sensation may find it too resistant, even with the softer insert installed. The pillow also has a mild initial odor that dissipates within a few days.

The IKSTAR pillow focuses on one core advantage: larger cutouts than most competitors. The side channels are visibly wider and deeper, which gives full-face masks significant clearance. If you use a mask like the Philips Respironics DreamWear or the Fisher & Paykel Vitera—both of which have larger frames—this pillow reduces the chance of the mask rim touching the foam and causing a leak. The cutout also has a curved shape rather than a sharp rectangle, which feels more comfortable against the cheekbone.

The adjustable height feature uses a 2 cm removable insert that sits under the base foam. This allows you to choose between a lower and a higher loft, though the range is narrower (roughly 1 inch) compared to the Elviros or Coop options. The memory foam is on the soft side, so it compresses more under weight, which can be a benefit for lightweight side sleepers but might not provide enough support for heavier individuals. The navy-colored cooling cover is removable and machine washable, though it is more of a cooling-feel fabric than a true active cooling layer.

The main limitation is the narrower loft adjustment—only two positions instead of four. If you need a very specific height between the two options, you may feel stuck. The soft foam also means the cutout can collapse slightly if you press your head very hard into the pillow.

HighBeds takes a different approach: a one-piece seamless cervical pillow that uses a two-zone height design (3.74 inches and 4.33 inches) rather than a removable shim. The cutouts for the CPAP mask are integrated into the sculpted contours instead of being a separate channel. This makes the surface feel smooth and uninterrupted, which some side sleepers prefer over the noticeable “trench” of a traditional cutout pillow. The 40D slow-rebound memory foam (3-7 seconds) provides a precise cradling effect that redistributes head weight evenly.

The pillow carries OEKO-TEX and CertiPUR-US certifications, so there is no formaldehyde or heavy metals in the foam. The 320g ice silk cover is heavier than standard pillowcase fabric and claims to sleep about 1°F cooler, which is noticeable if you run hot. The zipperless design means no zipper dig into your neck, and the cover is machine washable. HighBeds tested the foam for over 80,000 compression cycles, indicating long-term durability under daily use.

The downside is that the integrated cutout is not adjustable. If you use a mask with a very large side profile, the sculpted contour may not provide enough clearance. Side sleepers who always sleep on the same side will adapt quickly, but those who swap sides frequently may find the contour shape less accommodating than a symmetrical cutout.
