The Essentials
What Really Matters
Support without excessive sink
A supportive mattress should keep the sleeper stable through the night rather than allowing the hips or midsection to sink much more deeply than the rest of the body.
Construction and durability
Stronger spring units, denser comfort materials and robust edge construction can matter more when a mattress is under greater nightly load.
Pressure relief still matters
A supportive mattress does not need to feel harsh. Pressure relief remains important, particularly for side sleepers or anyone who dislikes a very firm surface.
Buying Advice
How to Choose a Mattress for Heavy People
Should heavier sleepers always choose a firm mattress?
Not always. Firm and medium-firm mattresses are common starting points because they can reduce excessive sink, but sleeping position and personal preference still matter. A heavier side sleeper may need more cushioning than a heavier back or front sleeper.
Pocket sprung, hybrid and foam options
Pocket-sprung and hybrid mattresses can provide a strong support core with useful airflow. Foam mattresses can also work when the materials are sufficiently supportive and durable. Construction quality matters more than the category label by itself.
How we selected the shortlist
We prioritised products in the My Ideal Mattress catalogue with high verified heavier-sleeper suitability scores, then considered overall quality, firmness, cooling and pressure relief. Always check the manufacturer's own suitability and weight guidance for the exact mattress and bed base.
Our Tip
Check both mattress and bed-base guidance: the mattress can only perform as intended if the base is suitable.
Our Tip
A firmer feel can help reduce excessive sink, but pressure relief and sleeping position still matter.

Questions
Frequently Asked Questions
Firm or medium-firm is often a useful starting point because it can reduce excessive sink, but the right choice depends on sleeping position, body shape and personal comfort preference.
They can be. Pocket springs can provide strong, responsive support, especially when combined with durable comfort layers and a suitable bed base.
Not necessarily a special category, but it is sensible to prioritise support, durability, edge stability and the manufacturer's own suitability guidance rather than choosing only by brand or price.
