Mattress for Seniors: How to Choose (2026 Guide)
Partilhar
Choosing a mattress for an elderly person — a father, a mother, or for yourself — involves criteria that don't appear in general guides. Firmness still matters, of course. But three things come first: how high the bed sits off the floor, how easily you can change position during the night, and hygiene.
1. Bed height is criterion number one
Most falls by elderly people at home happen around the bed — getting up at night, or sitting up in the morning. And bed height directly affects that risk.
The rule of thumb is simple: sitting on the edge of the bed, with feet flat on the floor, the knees should be at approximately 90 degrees. In practice, that gives a total height — bed base plus mattress — between 50 and 60 cm for most adults.
Do the maths before buying. A 26 cm mattress on a 30 cm bed base gives 56 cm: that works well. The same mattress on a high base with 35 cm legs gives 61 cm, and the person ends up sliding out of bed, which is exactly the movement we want to avoid.
If the bed already exists and is too high, a lower mattress corrects it. If it's too low, it's solved with taller legs on the bed base.
2. Firmness: medium-high, not high
There's an old idea that elderly people should sleep on very hard surfaces. That's not true, and it can be counterproductive.
With age, muscle mass and the fat layer over bony prominences decrease. The hip, shoulder and heels become more exposed to pressure. A mattress that's too hard concentrates pressure on those points; a mattress that's too soft hinders movement and lower-back support.
The balance usually lies in medium-high firmness with a comfort layer that redistributes pressure — typically memory foam or good-density high-resilience foam. Adjust by weight: see the firmness by weight table.
3. Ease of changing position
This criterion is almost always overlooked and is one of the ones that most affects the quality of the night. Those with reduced mobility need to be able to turn over without effort.
Pure memory foam is excellent at relieving pressure, but it "hugs" the body — and that makes turning over harder for those with little trunk strength. In these cases, I usually suggest one of two things: pocket springs with a thin layer of memory foam on top, or high-resilience foam, which springs back into shape faster.
The surface should give way enough to relieve the shoulder, but provide support back when the person pushes off to turn over. It's a balance you notice in the first few days.
4. Hygiene and protection
A waterproof, breathable mattress protector stops being optional. It protects against night sweats, spilled drinks or medication, and incontinence — and it's machine washable, unlike the mattress.
Look for three features: a fabric top layer (not plastic, which is noisy and hot), a breathable waterproof membrane, and washing at 60 °C. See mattress protector: is it worth it.
If respiratory allergies or asthma are involved — common in this age group — also see anti-mite mattress and allergies.
5. The weight of the mattress itself
A 26 cm queen-size spring mattress can weigh 35 to 45 kg. If the person making the bed is 78 years old, that matters far more than it seems at the time of purchase.
Two practical solutions: choose a mattress that doesn't need flipping (most current models only need head-to-foot rotation, not inversion), and choose fitted sheets with elastic all around, which can be changed without lifting the mattress.
6. Temperature
Thermoregulation worsens with age, and many elderly people complain of cold feet and a hot torso on the same night. Pocket spring mattresses ventilate better than closed foam blocks. If there are complaints of heat, avoid a thick layer of memory foam.
What I usually suggest
| Situation | Model | Why |
|---|---|---|
| Lower back pain, back sleeper | Hisui (翡翠) | High-resilience foam with memory foam, firm, 26 cm. Continuous lower-back support |
| Prefers a firm feel, complains of heat | Mizu (水) | Springs and high-resilience foam, 23 cm, high firmness, good ventilation |
| Reduced mobility, needs to turn easily | Takumi (匠) | Pocket springs with comfort layer that provides support when turning |
| Lower bed, tight budget | Kumo (雲) | High-resilience foam, 20 cm. Lowers the total bed height |
The full range is at all mattresses.
Questions I get asked
Do I need an adjustable bed? Only if there's a clinical indication — reflux, respiratory problems, leg oedema, or extended time spent in bed. For healthy ageing with normal mobility, a fixed bed at the right height works better and costs less. If you opt for an adjustable one, confirm the mattress is compatible: not all spring mattresses are.
Is an orthopaedic mattress the same as a mattress for seniors? No. "Orthopaedic" is not a regulated category. See orthopaedic mattress: what it is.
Two separate beds or one double bed? If the two of you have different firmness needs or very different schedules, two 90 cm beds pushed together solve this without separating the couple. It's a practical and widely used solution.
How often should it be replaced? The general reference is 10 years, but bring it forward if there's visible sagging or new complaints on waking. See when to replace your mattress.
"Before we talk about firmness, I always ask the same thing: measure the height of the current bed, from the floor to the top of the mattress. It's the number that most changes the daily life of whoever sleeps there." — Ana Cristina, Sleep Advisor
If there are pressure ulcers, very limited mobility, a post-operative period, or extended time spent in bed, talk to the attending doctor or a physiotherapist before deciding. There may be a need for specific equipment, which falls outside the scope of a domestic mattress.
How to decide
Measure the bed height. Confirm the person's weight and the position they sleep in. Choose the firmness from the table. Add a breathable waterproof protector. Only compare prices at the end.
