by The best mattress for pressure ulcers needs to keep peak interface pressure below the 32 mmHg capillary closure threshold at bony prominences. Our top pick is the Amerisleep AS3: its HIVE 5-zone layer adds cushion at the shoulders and hips (NapLab scores its pressure relief 10/10), and it sleeps cool for all-foam (NapLab cooling 9/10). We have not measured interface pressure ourselves. The Saatva Classic is the strongest hybrid alternative for heavier patients or those who need white-glove delivery.
Amerisleep AS3
9.2/10
- Pressure relief 10/10 (NapLab), with a zoned HIVE layer
- Sleeps cool for all-foam (NapLab cooling 9/10)
- CertiPUR-US certified, made in the USA
- 100-night risk-free trial and 20-year warranty
- Softer edges than a coil hybrid
- Sleepers above 230 lbs may bottom out at the hips over time; the AS3 Hybrid is the better call
The AS3’s zoned HIVE layer and NapLab pressure-relief score describe consumer comfort, not proven pressure ulcer prevention or suitability for long-term care; talk to your doctor about an appropriate support surface.
How We Rate
These are MattressNut's editorial ratings, based on construction, brand specifications and independent lab data where available (NapLab). They are not results from our own lab tests, and no consumer mattress replaces clinical pressure-injury equipment. Scores are updated June 2026.
The best mattress for pressure ulcers needs to do one thing above everything else: keep peak pressure below the capillary closure threshold of around 32 mmHg at bony prominences. The Amerisleep AS3 earns the top spot here for its zoned HIVE layer and a 10/10 pressure-relief score from NapLab. It also sleeps cool for all-foam (NapLab cooling 9/10), and the 20-year warranty signals confidence in long-term durability.
If you are a heavier sleeper above roughly 230 lbs, the AS3 can bottom out at the hips over time. The AS3 Hybrid, with a pocketed coil base, is the better call in that case. Here, the AS3 covers the majority of pressure-ulcer patients and caregivers shopping for a residential mattress.

Why pressure ulcers demand specific mattress properties
A pressure ulcer forms when capillary blood flow is cut off by sustained load against bone. The most common sites are the sacrum, heels, and lateral hips. Pressure-injury risk depends on pressure, duration, shear, perfusion and the person’s condition; no single pressure-and-time cutoff establishes protection. Dense traditional memory foam can actually exceed this threshold at the hip because it bottoms out and then pushes back, creating a hammocking pressure spike right where you want relief. Zoned foam architectures like the AS3's HIVE layer avoid this by differentiating stiffness by body region rather than using uniform density throughout.
Temperature matters too. Warm skin is more susceptible to breakdown, so a mattress that runs cooler than a dense foam bed provides a secondary layer of protection. NapLab measured an 85.4°F peak surface temperature on the AS3 and scores it 9/10 for cooling.
What to look for, and what to ignore
Most marketing claims on pressure-relief mattresses focus on cover fabric or phase-change material, but neither meaningfully affects interface pressure at depth. What does matter: foam ILD at the hip and heel zones, zoning architecture, and total foam depth above coils or base foam. A bed with 3 inches of pressure-relief foam above a firm transition layer will outperform a 13-inch mattress where that relief layer is only 1.5 inches thick.
Firmness labeling is also misleading here. A plush mattress from a brand that tops out at 3-inch comfort layers may deliver higher hip pressure than a medium bed with 4 inches of well-tuned zoned foam. That is why we weigh comfort-layer depth and zoning more than the firmness label.
Saatva Classic
8.5/10
- White-glove delivery with in-room setup and old mattress removal included
- Zoned lumbar coils prevent hammocking for heavier bodies, which is critical for sacral pressure management
- 365-night trial, the longest here
- Lifetime warranty covers long-term residential care use
- Coil feel gives less deep contouring than the AS3's foam
- Scheduled white-glove delivery, so check lead times if you need it urgently
- $99 return fee applies during the trial
The Saatva Classic is the best hybrid pick for heavier pressure-ulcer patients above 230 lbs: its zoned lumbar coils provide deep support that prevents hammocking at the sacrum, and white-glove delivery is genuinely useful for caregivers who cannot manage a heavy compressed mattress box (the AS3 queen weighs 88 lb).
How repositioning schedules interact with mattress choice
A pressure-redistributing mattress slows ulcer formation but does not eliminate the need for repositioning. Clinical guidance typically recommends turning immobile patients every two hours, and some studies suggest higher-quality pressure redistribution surfaces can extend that window to four hours with monitoring. No consumer mattress can guarantee interface pressure below 32 mmHg, so keep to the repositioning schedule your care team recommends.
Caregiver access is a practical factor most reviews ignore. The Saatva Classic arrives with white-glove setup, which matters when the person who ordered it cannot easily lift a compressed mattress box. The AS3 ships compressed and requires unrolling, which takes two people. Neither answer is wrong, but worth factoring in before you order.
Puffy Original
8.3/10
- Uniform cloud-like feel suits lighter patients under 150 lbs who spend extended time in one position
- Lifetime warranty at this price point is uncommon
- CertiPUR-US certified foam
- No zoned architecture; uniform density throughout
- Bottoms out faster than the AS3 for bodies over 180 lbs
The Puffy Original is the softest all-foam option on this page that delivers reliable pressure relief for lighter patients under 150 lbs. Its uniform foam works well for people who spend long stretches in one position, though spinal support falls short of the AS3 for anyone heavier.
Nectar Premier Copper
8.4/10
- Copper-infused foam and phase-change cover reduce surface temperature, and warm skin is more susceptible to breakdown
- Deep contouring relieves hip and shoulder pressure effectively
- 365-night trial and lifetime warranty
- No zoned architecture; pressure distribution at depth trails the AS3
- Not as breathable as a hybrid for heavier sleepers
The Nectar Premier Copper is the standout pick for hot sleepers who also need deep pressure contouring: its copper-infused foam and phase-change cover are designed to run cooler than the standard Premier.
Medical-grade versus residential mattresses
True medical-grade alternating-pressure mattresses, the kind used in hospital ICUs, operate on powered air cells that cyclically offload pressure zones on a timer. Talk to your doctor or care team about which pressure-redistributing support surface may be appropriate for a fully immobile patient. People with limited mobility or recovering at home from surgery should talk to their doctor or care team about pressure-injury risk and an appropriate support surface. If you or someone in your care has a current stage III or IV ulcer, speak with a wound care specialist about clinical-grade equipment before making a residential purchase.
When a mattress topper makes more sense
If you are sleeping on a mattress with a serviceable support core but a worn or too-firm comfort layer, a topper is the faster and cheaper fix. A 2-inch medium-density memory foam topper (around 3 to 4 lb/ft3 density) can noticeably reduce hip pressure on a firm surface. Toppers on an old or sagging base mattress do not work, because the foam beneath still deforms, pulling the topper with it, and the bony prominence ends up in the same position. Fix the base first.
For pressure ulcer prevention, choose a medium mattress with zoned foam architecture and strong independent pressure-relief scores. The Amerisleep AS3 is our top pick with a 100-night trial and 20-year warranty. The Saatva Classic is the best hybrid alternative for heavier patients who need white-glove delivery.
Frequently asked questions
What mattress firmness is best for preventing pressure ulcers?
There is no universal consumer mattress firmness prescription for preventing pressure ulcers. Talk to your doctor or care team about an appropriate support surface for your individual clinical needs. Consumer comfort ratings and zoned foam features should not be treated as evidence that a mattress prevents pressure ulcers.
Can a regular mattress cause or worsen pressure ulcers?
Yes, in people who spend extended time in one position. A worn mattress with a collapsed comfort layer or a uniformly firm surface that does not contour around bony prominences will push interface pressure above the 32 mmHg capillary closure threshold faster. This matters most for back or side sleepers who are relatively immobile; the sacrum, heels, and lateral hips are the primary sites.
How long should I try a mattress before deciding it works?
Seek prompt advice from your doctor or care team if you notice skin injury or persistent pressure-related symptoms. Do not wait through a mattress adaptation period to assess a possible pressure injury. A consumer sleep trial is not a substitute for clinical review or individualized support-surface selection.
