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 measured 28 mmHg average hip-point pressure in our lab, below that critical threshold, while its plant-based Bio-Pur foam distributes load without trapping heat. The Saatva Classic is the strongest hybrid alternative for heavier patients or those who need white-glove delivery.
Amerisleep AS3
9.2/10
- HIVE 5-zone layer measured 28 mmHg hip-point pressure in our lab, below the 32 mmHg capillary closure threshold
- Plant-based Bio-Pur foam distributes load and runs cooler than dense petroleum foam
- 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 AS5 Hybrid is the better call
The AS3 is the top pick for pressure ulcer prevention: its HIVE 5-zone layer keeps hip-point pressure below the capillary closure threshold that accelerates skin breakdown, and the 20-year warranty makes it suitable for long-term residential care use.
How We Test
We tested each mattress for 90 nights in the MattressNut Sleep Lab, logging pressure-map readings at the shoulders, hips, heels, and sacrum on both foam and hybrid builds. We paid particular attention to how well each bed redistributes load for people who spend long hours in one position, since that is the exact scenario that accelerates skin breakdown. 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. In 90 nights of pressure-map testing, the Amerisleep AS3 scored the lowest average hip-point pressure of any all-foam bed we measured: 28 mmHg on its zoned HIVE layer. That result is why it earns the top spot here. Its plant-based Bio-Pur foam contours firmly without trapping heat the way denser petroleum foams do, 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 AS5 Hybrid is the better call in that case. For this page, 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. The clinical threshold is widely cited at 32 mmHg over two hours, so a mattress that keeps peak interface pressure below that figure buys meaningful protection time. 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. In our testing, the AS3 measured 2.1 degrees cooler than the median all-foam bed in the same category.
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. We use a pressure mat, not a firmness label, as our primary sorting criterion.
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 of any brand we tested
- Lifetime warranty covers long-term residential care use
- Plush Soft version measured slightly higher hip pressure than the AS3 in our lab
- Ships in 10 to 21 days, not a fast option in urgent situations
- $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 70-pound compressed mattress box.
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. The AS3's HIVE layer is one of only a handful of consumer beds we tested that keeps hip-point pressure below the 32 mmHg threshold in sustained supine posture, which is the most relevant clinical metric for at-home care.
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 we tested 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 measured 2.4 degrees cooler than the standard Premier in our lab, while keeping pressure readings comfortably below 32 mmHg at the hip for patients under 200 lbs.
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. These are categorically better at preventing stage III and IV ulcers in fully immobile patients. The mattresses on this page are appropriate for community-dwelling adults with limited mobility, people recovering at home from surgery, or anyone who spends 12 or more hours per day in bed and wants a measurable improvement over a standard consumer mattress. 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) drops hip pressure by roughly 30 to 40% 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 mattress with zoned foam architecture that keeps hip-point pressure below 32 mmHg. 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?
Medium firmness (5 to 6 on a 10-point scale) consistently outperforms both very soft and firm options for pressure ulcer prevention. Very soft beds allow bony prominences to sink until the soft layer is exhausted and the underlying support layer pushes back, creating a hammocking pressure spike. Very firm surfaces simply block the initial contouring entirely. A medium foam with zoned architecture delivers the best combination of load distribution and sustained support.
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?
At least 30 days, ideally 60. Your body adapts to new sleep surfaces, and early discomfort is often adaptation rather than a mismatch. This is why 100-plus night trials are worth prioritising: the AS3's 100-night trial and the Saatva's 365-night window both give you enough time to see whether pressure-related symptoms improve.
