Lunderg CPAP Pillow for Side & Back Sleepers – Memory Foam

Top pick

The Lunderg’s contoured cutouts and adjustable memory foam layer make it a practical choice for CPAP users who switch between side and back sleeping. The pillow’s firm slow-rebound foam holds its shape overnight, reducing mask shifting and air leaks, especially for full-face masks.

The removable foam insert lets you tailor the loft, and the two included pillowcases offer both a soft and cooling option, so you don’t need to switch to a regular pillow while washing covers. Mask pressure and tubing interference drop noticeably, and the pillow helps prevent neck aches and stuffy noses common with standard pillows.

The firmness is a standout for people used to memory foam, but it feels too rigid for those who prefer softer or down pillows, one reviewer described waking up with headaches and a stiff neck after a few months. The pillow’s unique top and bottom patterns mean you need to pay attention when putting on the case, which adds a minor learning curve.

Sleep quality improves for most side sleepers, especially those struggling with mask seal loss or frequent tossing. However, if you dislike firm pillows or want a softer, sink-in feel, this one won’t suit you.

The cooling cover doesn’t noticeably differ from the regular one, but the pillow outperforms standard options for CPAP compliance.

Where it wins

  • Reduces mask pressure and air leaks for side sleepers
  • Adjustable height with removable foam layer
  • Firm slow-rebound foam maintains support overnight
  • Includes two machine-washable pillowcases (soft and cooling)
  • Compatible with all mask types and brands

Where it falls short

  • Feels very firm, not suitable for those who prefer softer pillows
  • Cooling cover isn’t noticeably cooler than the regular cover
  • Some users experience headaches or stiff neck after extended use

HSA/FSA CPAP Pillow for Side Sleepers with Larger Cutouts

Best value

The pillow’s larger cutouts and contoured sides make it easier for CPAP masks to sit naturally, so mask pressure and air leaks drop even when you shift positions. The adjustable height feature lets you fine-tune the pillow’s loft, and the memory foam gives balanced neck support for side, back, or stomach sleepers.

The cooling cover is breathable and easy to wash, making it a practical upgrade from standard pillows. The pillow performs especially well for those who toss and turn or change sides overnight, as the mask stays in place without hose tugging or seal loss.

The ergonomic center cradle and supportive wings help align your neck and spine, reducing discomfort and waking. The memory foam is slow-rebound and supportive, but some find it firmer than expected, so it’s not ideal if you prefer a softer feel.

All-position compatibility and the easy-care cover make it a good pick for anyone who uses nasal, full-face, or pillow masks. If you want a pillow that’s softer or more plush, this pillow’s firmness might disappoint.

The cooling fabric works well for most, but doesn’t stand out as dramatically cooler than regular covers.

Where it wins

  • Larger cutouts reduce mask pressure and air leaks
  • Adjustable height for custom comfort
  • Ergonomic contour supports neck alignment
  • Cooling, breathable, washable cover
  • Fits most CPAP mask types and sleep positions

Where it falls short

  • Memory foam feels firmer than some expect
  • Cooling cover isn’t significantly cooler
  • Not ideal for those who prefer plush pillows

CPAP users who switch mask types and need neck support for multiple sleep positions

HSA/FSA CPAP Pillow for Side Sleepers

Best for Cpap

The dual cutouts reduce pressure points and prevent tubing entanglement, so CPAP users wake up less during the night. The ergonomic design supports natural neck and spine alignment for side, back, and stomach sleepers.

Adjustable loft heights on each end (3.93 and 3.74 inches) accommodate different body types and sleep preferences, offering flexibility for those who need a higher or lower profile. The CertiPUR-US certified memory foam is medium-firm and stable, maintaining support all night without flattening.

The pillow’s central head cradle aids muscle relaxation and helps reduce snoring and shoulder tension. The breathable, machine-washable cover keeps the sleep environment dry and comfortable, though the pillow doesn’t stand out for cooling compared to others.

People who need odorless, supportive foam and switch mask types benefit most from this pillow. If you prefer a very soft pillow or need dramatic cooling effects, this one may not meet expectations.

The pillow is practical for anyone who wants flexibility in mask choice and sleep position, but not for those seeking plush comfort.

Where it wins

  • Dual cutouts minimize mask pressure and tubing entanglement
  • Supports all sleep positions (side, back, stomach)
  • Adjustable loft heights for custom comfort
  • Medium-firm memory foam maintains support overnight
  • Breathable, washable cover

Where it falls short

  • Not as soft as some expect
  • Cooling is adequate but not exceptional
  • Some may find the loft too low or too high

Larger men who need a tall, firm pillow for CPAP mask support

CPAP Pillow for Larger-Framed Men

Best for Larger

Engineered for larger-framed male CPAP users, this pillow stands out for its extra height (up to 5.9 inches) and four-stage adjustability. The C-shaped area keeps tubing organized and reduces air leaks, while the progressive perforation pattern inside the pillow balances support and breathability.

The CertiPUR-US core delivers stable, ergonomic support, helping alleviate neck pain for those who need a higher loft. The OEKO-TEX certified pillowcase feels cool to the touch and is easy to wash, minimizing heat buildup and sleep interruptions.

Neck pain relief is a highlight, especially for side and back sleepers needing substantial support. Users should allow 48-72 hours for full rebound and expect a slight foam odor for the first few days.

The pillow is not a clinically approved device, so those with severe neck issues should consult a doctor before use. If you’re a smaller-framed user or dislike thick pillows, this pillow’s height and firmness will likely feel excessive.

The pillow takes up more space than standard options and requires a week or two to adjust to its ergonomic curve. It’s best for men who need a tall, firm pillow to prevent mask leaks and facial pressure.

Where it wins

  • Extra height and width for larger-framed users
  • Four adjustable height settings for custom support
  • C-shaped area organizes tubing and reduces air leaks
  • Perforated design enhances airflow and cushioning
  • Cool, OEKO-TEX certified pillowcase

Where it falls short

  • Too thick for smaller-framed users
  • Initial foam odor requires airing out
  • Takes 1-2 weeks to adjust to the ergonomic curve

Side sleepers with neck pain seeking precise support and adjustable firmness

Ergo Cervical Neck Pillow for Neck Pain & Sleep Apnea

Best for Side

This pillow’s dual-height contour and deep neck cradle fill the gap between shoulder and head, keeping the spine aligned and relieving pressure points for side sleepers. The high-density CertiPUR-US memory foam balances gentle cradling and firm support, letting you choose between a soft or firm feel.

The booster pad offers a subtle height boost for reading or scrolling, and can be tucked inside the pillowcase for smooth adjustment. The cooling cover is ultra-soft and machine washable, often described as the softest cover people have owned.

The pillow recovers quickly from compression and has minimal foam odor, so you can use it soon after airing out. It helps reduce tossing, improves breathing, and supports deeper sleep, making it ideal for side and back sleepers with neck pain or sleep apnea.

If you need more extreme adjustability or prefer a pillow with pronounced mask cutouts, this pillow may disappoint. The cover is so soft that some may skip a pillowcase, but replacement covers and booster pads are available.

It’s best for those seeking orthopedic neck support and customizable firmness.

Where it wins

  • Dual-height design relieves neck pain for side sleepers
  • Choose between soft and firm memory foam
  • Booster pad for adjustable loft
  • Ultra-soft, machine washable cooling cover
  • Minimal foam odor, quick recovery

Where it falls short

  • Limited mask cutout features compared to CPAP-specific pillows
  • Best for neck pain relief, not dramatic mask seal improvement
  • Requires separate purchase for more booster pad options

What actually matters

Mask cutout shape and size

Deep, crescent-shaped cutouts allow your CPAP mask to rest without pressure, which is essential for side sleepers. Pillows with shallow or poorly placed cutouts can cause leaks and discomfort. Check that the cutout matches your mask type and sleeping position. Avoid basic center holes, they rarely offer enough clearance for masks.

Firmness and support

A firm pillow keeps your head and neck aligned and prevents mask straps from slipping. Too-soft pillows flatten over time, leading to neck pain and disrupted sleep. Look for memory foam or ergonomic designs that hold shape after months of use. Skip pillows that feel squishy or lose loft quickly.

Adjustable height or loft

Being able to adjust the pillow height is vital if you have broad shoulders or prefer a higher loft. Some pillows include removable layers for customization. Make sure the pillow fits your body size; a pillow that’s too low won’t support your neck, while one too high causes strain.

Compatibility with mask types

If you switch between nasal and full-face masks, you need a pillow with dual cutouts or flexible shaping. Pillows that only fit one mask type limit your options. Always check whether the pillow’s design works for your CPAP mask before buying.

Neck and shoulder alignment

Ergonomic shaping keeps your spine aligned and prevents neck pain. Look for pillows with raised edges or cervical support. Avoid flat pillows that don’t cradle the neck or shoulders, especially if you wake up sore.

Frequently asked questions

Does sleeping on 2 pillows help sleep apnea?
Stacking two pillows usually raises your head too much, which can kink your neck and worsen sleep apnea symptoms. Instead, choose a single pillow with proper contouring and support specifically designed for CPAP users.
Is sleeping on your side good for sleep apnea?
Sleeping on your side generally reduces sleep apnea symptoms by keeping airways more open compared to sleeping on your back. Side sleeping is often recommended for people with mild to moderate sleep apnea.
Is sleeping on your side better for sleep apnea?
Yes, side sleeping is better for most people with sleep apnea. It lowers the risk of airway collapse, helping your CPAP machine work more effectively and improving overall sleep quality.
Can pillows cause sleep apnea?
Pillows themselves don’t cause sleep apnea, but the wrong pillow can worsen symptoms by forcing your neck into an awkward position and partially blocking your airway. Using a supportive CPAP pillow helps prevent these issues.
Does a neck pillow help with sleep apnea?
A neck pillow with proper ergonomic support can reduce airway obstruction and neck pain for sleep apnea sufferers. Look for pillows designed to support your neck and keep your airway open.
Can you sleep on your side when using a cpap machine?
You can sleep on your side with a CPAP machine, but you need a pillow with deep mask cutouts to prevent leaks and discomfort. Many CPAP pillows are specifically designed for side sleeping to solve this problem.
