Hypnos Cotton Deluxe Bedstead Medium Firm Mattress

Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.

A medium firm pocket spring build suits most sleepers, giving enough give for side sleeping while keeping support for back sleepers. The pocket springs respond to your body individually, which means better contouring and less disturbance from a partner turning over. Retailer information points to premium natural fillings, which tend to breathe better than synthetic foams, a plus if you sleep warm. This is a considered purchase rather than a budget buy, but Hypnos is a long-established British maker and the pocket sprung construction here is a step up from basic open coil designs. Mattressman lists a 60-night trial, which gives you time to adjust before committing.

Back sleepers
The medium firm tension keeps support under the spine, which means your body stays level without feeling like you are lying on a board.

Couples
Individually responding ReActivePro 8 turn pocket springs give better contouring and less disturbance when a partner turns over during the night.

Warm sleepers
Premium natural fillings tend to breathe better than synthetic foams, which means less trapped heat if you often wake up too warm.

Combination sleepers
Medium firm pocket springs offer enough give for side sleeping while keeping support for the back, so changing position through the night feels comfortable.

If you want a soft, sink-in feel, this medium firm tension will likely feel too solid, particularly for lightweight side sleepers. Its starting price is also a stretch for tighter budgets. And if you prefer full construction transparency, the published spec is a little thin on layer details.

Is the Hypnos Cotton Deluxe Bedstead mattress firm or soft?

It's rated medium firm. That sits in the middle-to-supportive part of the scale, which suits most back and combination sleepers, although lightweight side sleepers may find it slightly too firm for comfortable pressure relief at the shoulders and hips.

What sizes does the Hypnos Cotton Deluxe Bedstead come in?

It's available in UK Single, Double, King and Super King.

Does the Hypnos Cotton Deluxe Bedstead come with a trial period?

Mattressman lists a 60-night trial with this mattress. That's the retailer's own offer rather than a Hypnos guarantee, so if you buy elsewhere, check that retailer's returns policy before ordering.

What type of mattress is the Hypnos Cotton Deluxe Bedstead?

It's a pocket spring mattress. Retailer information references ReActivePro 8 turn pocket springs and premium natural fillings, which means individually responsive support and breathable comfort layers, though a full layer breakdown isn't published.
