If you sleep on your side and use CPAP therapy, a regular pillow may press against your mask or pull at the hose when you turn. A CPAP pillow with side cutouts can create more room for mask hardware, while a contoured cervical pillow may suit you better if neck alignment is your main concern. The options below vary in firmness, height, and mask clearance. A pillow can improve comfort, but it does not treat sleep apnea or replace prescribed therapy.

Our Picks: Best Pillows For Side Sleepers With Sleep Apnea reviews
1. IKSTAR Cooling CPAP Pillow: A Mask-Friendly Pick for Side Sleepers
The IKSTAR pillow is designed for people who want a dedicated CPAP shape rather than a standard bed pillow. Its side cutouts are intended to give mask hardware and tubing more room when you lie on your side. The product description also says it is compatible with common mask styles, including full-face, nasal, and nasal-pillow masks.
Memory foam forms the support core, while the included pillowcase is described as smooth and breathable. The shaped design may help reduce direct pillow contact with a mask, but the result will depend on your mask, sleeping position, and how the pillow fits your shoulders and head. A new pillow can also take time to get used to, especially if its contour differs from your current one.
This option stands out for its CPAP-specific cutouts and smooth pillowcase. It is listed as HSA/FSA eligible in the product details, but eligibility can depend on your plan and purchase requirements, so confirm before ordering. Compared with the IKSTAR model with larger cutouts below, this one does not list an adjustable-height insert.
Pros:
- Side cutouts are designed to make room for mask hardware and tubing.
- Memory foam is intended to provide shaped head and neck support.
- The product description lists compatibility with several common mask styles.
- Listed as HSA/FSA eligible in the supplied product information.
Cons:
- No adjustable height feature is listed.
- The best fit may vary with your mask shape and shoulder width.
Verdict: Choose this IKSTAR model if you want a CPAP-focused pillow with side cutouts and do not need a removable height insert.
2. Ergo Pillow for Sleep Apnea: Contoured Support with Two Loft Levels
This contoured memory foam pillow is aimed at sleepers who want neck support rather than a pillow built around CPAP mask cutouts. It has two loft levels: the higher side is intended for side sleeping, while the lower profile is designed for back or stomach sleeping. Its curved shape is meant to fill the space between the head and shoulder.
The slow-rebound foam is described as firm yet adaptive, and the removable cover has a breathable structure. The cover is machine washable according to the product details. Those features may appeal if you want a shaped pillow that is easier to care for, though this design does not list dedicated side cutouts for CPAP masks or tubing.
Compared with the CPAP-specific options in this guide, this pillow may be a better match when neck contour and multiple loft choices matter more than creating space around a mask. Pillow height is personal: a loft that supports one side sleeper may feel too high or low for another, depending on shoulder width and mattress softness. The product description also advises allowing the compressed foam time to expand and air out after opening.
Pros:
- Two loft levels offer a choice for different sleep positions.
- Contoured foam is designed to support the head and neck.
- Removable cover is described as machine washable.
- Breathable cover design may suit sleepers who tend to feel warm.
Cons:
- No CPAP mask cutouts are listed.
- Its contoured shape may take adjustment if you are used to a flat pillow.
Verdict: Consider this pillow if you want two loft choices and neck contouring, but look to a cutout model if mask pressure is your main concern.
3. IKSTAR CPAP Pillow with Larger Cutouts: Adjustable Mask Clearance
This IKSTAR model is designed for CPAP users who want more space around their mask while side sleeping. Its larger cutouts are intended to reduce contact with mask hardware, and the contoured sides provide room for the hose. The product description lists compatibility with most nasal, full-face, and nasal-pillow mask types.
A removable two-centimeter insert lets you adjust the pillow height. That makes this option more flexible than a fixed-loft CPAP pillow, though it still may not suit every body or mattress combination. The foam has a center cradle and side wings, and the cover is removable and washable. The product details also list HSA/FSA eligibility, which you should confirm for your own plan before purchasing.
Compared with the first IKSTAR pillow, the main stated difference is the larger cutouts and adjustable height. Those features may be useful if you change sides during the night or need to fine-tune your neck position. The pillow’s dimensions and cutout placement still need to work with your particular mask and sleeping setup; a cutout is not a guarantee of a leak-free seal.
Pros:
- Larger cutouts are designed to provide more room around mask hardware.
- Removable insert lets you adjust the pillow height.
- Designed for several common CPAP mask styles.
- Removable, washable cover is listed in the product details.
Cons:
- The shaped cutouts may not line up equally well with every mask and face shape.
- Adjusting to the contour and height may take time.
Verdict: This is a strong option to consider if you want CPAP-specific cutouts with more room and the ability to change the loft.
4. Farrumex CPAP Pillow: A Firmer Feel with a Removable Layer
The Farrumex CPAP pillow is built for sleepers who prefer a more structured feel. Its high-density memory foam core is described as firmer than the brand’s earlier version, with less deep sinking than a softer pillow. Mask-relief cutouts are designed to make room for common full-face, nasal, and nasal-pillow mask styles, along with tubing.
You can keep or remove the listed 0.79-inch layer to change the pillow height. This gives you a way to adjust the setup without changing the firmer feel of the core. The cover is removable, cool-touch, and machine washable according to the product information.
Compared with the adjustable IKSTAR model, Farrumex emphasizes a firmer feel and a removable layer rather than larger cutouts. That may appeal if softer foam collapses too much under your head, but a firm pillow can feel less forgiving if you prefer a plush surface. Check the cutout position against your mask before deciding whether the shape is likely to work for you.
Pros:
- Firmer foam core is designed for stable support with less sinking.
- Cutouts are intended to create room for mask hardware and tubing.
- Removable layer gives you a choice of pillow height.
- Removable cover is described as machine washable.
Cons:
- The firm feel may not suit sleepers who prefer a soft, plush pillow.
- Cutout fit can vary with your mask and sleeping position.
Verdict: Pick the Farrumex if you want a CPAP pillow with a firmer core and a simple way to adjust its height.
5. BDEUS Cervical Pillow: Butterfly Contour for Side-Sleeping Support
The BDEUS pillow uses a butterfly-shaped contour with a side zone intended to support the head and neck while leaving space for the shoulder and arm. Its two listed heights are 5.1 inches for side sleeping and 4.7 inches for back sleeping. The product description says the shape is designed to support alignment, but the fit will depend on your body and preferred sleep position.
High-density memory foam forms the core, and the removable cover is described as cooling. Unlike the CPAP-specific picks above, this product does not list mask-relief cutouts. That distinction matters if your main issue is a mask being pushed by the pillow; a contoured neck pillow may not provide the same hardware clearance as a dedicated CPAP design.
The product data currently marks this option as unavailable, so it may not be a practical choice if you need a pillow now. Availability can change, but it is sensible to compare the other options first. The product description also notes that the shaped support may limit easy turning, so restless sleepers should weigh that trade-off.
Pros:
- Butterfly contour includes a shaped side-sleeping zone.
- Two listed heights are intended for side or back sleeping.
- High-density foam and a removable cooling cover are specified.
- May suit someone prioritizing neck contour over CPAP mask cutouts.
Cons:
- Marked unavailable in the supplied product information.
- No CPAP mask cutouts are listed, and the shape may limit turning.
Verdict: Consider the BDEUS only if it becomes available and you want a contoured cervical pillow; for mask clearance, a CPAP-specific cutout model is a more direct match.
How to Choose a Pillow for Side Sleeping with Sleep Apnea
Decide Whether You Need Mask Clearance or Neck Contour
If you use a CPAP mask, first consider whether the pillow presses against it or catches the hose when you turn. Side cutouts are designed to create space for mask hardware, while a standard cervical contour focuses more on head and neck support. These features solve different comfort problems, so match the shape to what bothers you most.
Check the Pillow Height Against Your Body
A pillow should support your head without forcing your neck sharply up or down. Side sleepers often need more loft than back sleepers, but the right height also depends on shoulder width, mattress softness, and how deeply your head sinks into the foam. Removable inserts or dual-height designs give you more room to adjust, but they do not guarantee a perfect fit.
Choose a Firmness You Can Sleep On
Memory foam can feel different from a traditional fiber-filled pillow. Firmer foam may provide a more stable base, while softer foam may feel more yielding. If you are unsure, consider whether your current pillow feels too flat, too firm, or too soft, and use that as a guide. A strong contour or a firm core can take time to get used to.
Match Cutout Placement to Your CPAP Mask
Mask styles and shapes vary, so look for a pillow that says it is designed for your type of mask. Side cutouts can make room for a mask, but they may not align with every face, mask frame, or sleeping position. If you change sides during the night, consider whether the pillow gives you usable support and clearance on both sides.
Consider Cover Care and Warmth
Removable, washable covers are useful for regular care. Breathable or cooling-feel fabrics may appeal if you tend to overheat, though no cover can promise a certain sleep temperature. Check whether the cover is machine washable and follow its care instructions to help maintain its fit and feel.
Keep Sleep Apnea Treatment in Perspective
A pillow may help you feel more comfortable or reduce pressure on a mask, but it is not a substitute for CPAP or other treatment prescribed by a healthcare professional. Do not stop or change your therapy based on a pillow’s product claims. If you continue to have mask leaks, discomfort, or concerns about your treatment, contact your sleep-care team or equipment provider.
Frequently Asked Questions
Can a pillow cure or treat sleep apnea?
No. A pillow may affect comfort and positioning, but it is not a treatment for sleep apnea. Continue the therapy recommended by your healthcare professional and ask them about treatment concerns.
Do CPAP pillows stop mask leaks?
Cutouts are designed to reduce contact between the pillow and mask, which may help with some sources of pressure or disturbance. They cannot guarantee a leak-free seal because fit also depends on the mask, its adjustment, and your sleeping position.
Are CPAP pillows only for side sleepers?
No. Some CPAP pillows are shaped for side sleeping but may also be used in other positions. Check the product’s design and height options, and consider whether its contours work for the way you usually sleep.
How do I choose between an adjustable pillow and a fixed shape?
An adjustable design lets you change the height or remove a layer, which can help if you are unsure about the best loft. A fixed shape may be simpler, but you have fewer ways to fine-tune its fit. In either case, the shape should work with your mask and neck position.
Will a cooling cover keep me from overheating?
A breathable or cooling-feel cover may be more comfortable for some sleepers, but it cannot guarantee that you will stay cool. Room temperature, bedding, and personal comfort also matter.
What should I do if my CPAP mask still feels uncomfortable?
Check that your mask and hose are positioned as directed, and contact your equipment provider or sleep-care team if discomfort or leaks continue. A different pillow may help with contact or support, but it may not solve a mask-fit issue.
Final Recommendation
For most side sleepers using CPAP, start with a pillow designed to leave space around the mask. The IKSTAR model with larger cutouts is the most adjustable option in this group, while the Farrumex is a better fit to consider if you prefer a firmer feel. If neck contour and multiple loft levels matter more than mask clearance, the Ergo pillow offers a different approach. Choose based on your mask, shoulder width, preferred firmness, and sleep position—and keep using your prescribed sleep apnea treatment.
