Pressure-relief mattresses
When someone spends long stretches in bed, the steady pressure of lying still can damage the skin — leading to pressure injuries, sometimes called bedsores. A pressure-relief mattress, paired with a simple repositioning routine, is one of the most effective ways to protect the skin. Here is how the types differ and who each suits.
Why pressure is the enemy of resting skin
The problem these mattresses solve
Pressure injuries form where the body presses against a surface for too long — usually over bony areas like the heels, hips, tailbone, and shoulders. The constant pressure squeezes the small blood vessels in the skin, and without that blood flow the tissue starts to break down. They can develop surprisingly quickly in someone who cannot shift their own weight.
Two things prevent them: redistributing or relieving the pressure, and repositioning the person regularly so no single spot bears the load for too long. A pressure-relief mattress does the first; a caregiver routine does the second. They work best together — no mattress replaces turning and checking the skin.
The main types
From simple to more active. The right choice depends on how mobile the person is and how high their risk of skin breakdown. By type, not brand.
High-specification foam
Therapeutic foam that spreads weight across a wider area, often with channels for airflow. Quiet, low-maintenance, and well suited to lower-risk or shorter-term needs.

Alternating-pressure mattresses
Rows of air cells inflate and deflate in turn, so the points of contact constantly change. This active relief suits people with limited mobility and higher risk.

Low-air-loss systems
A blower gently circulates air to manage moisture and temperature against the skin — helpful when sweat and dampness add to the risk of breakdown.

Combination systems
Some mattresses pair alternating pressure with low air loss, giving both dynamic pressure relief and moisture control for the most complex, highest-risk needs.
ExploreProtecting the skin day to day
The mattress is half the job. These habits are the other half — adapt the timing to your care team's advice.
Reposition on a schedule
Help the person change position regularly so no single area bears pressure too long. A gentle, predictable routine works better than waiting until discomfort sets in.
Check the skin every day
Look at the heels, hips, tailbone, and shoulders for redness that does not fade. Catching an early warning sign is far easier than treating an established injury.
Keep skin clean and dry
Moisture weakens skin and speeds breakdown. Gentle cleaning and keeping bedding dry are simple but powerful protections, especially alongside incontinence care.
Match the mattress to the bed and risk
Confirm the mattress fits the bed frame, and choose the type to match the person's mobility and risk level. Remember that a softer specialty mattress can change bed-rail gaps — check rail safety if rails are in use.
Common questions
Do I need an air mattress, or will a foam one do?
It depends on mobility and risk. For someone who still shifts position fairly often and is at lower risk, a high-specification foam mattress may be enough. For someone who cannot reposition themselves and is at higher risk, an alternating-pressure or low-air-loss system provides the active relief that foam alone cannot.
Does a pressure-relief mattress mean I can stop turning the person?
No. Even the best mattress is meant to work alongside regular repositioning, not replace it. Turning, daily skin checks, and keeping skin clean and dry remain essential — the mattress reduces risk, it does not remove the need for care.
What is the first sign of a pressure injury?
Often a patch of skin over a bony area that stays red and does not blanch (fade) when pressed, or that feels warmer, firmer, or more tender than the skin around it. If you see this, relieve pressure from that spot and contact the care team — early action makes a real difference.
