The Dormeo Fresh Deluxe combines 4cm of memory foam with a supportive foam base, coming in at 20cm deep, so it sits on the slimmer side for a foam mattress. It comes in UK Single, Double and King sizes, and Dormeo backs it with a 200-night trial and a 20-year guarantee, both generous by any measure. It suits side sleepers and those who like a softer, cradling feel, although heavier sleepers or anyone who prefers a firm surface may find it a little too yielding.

Why should you choose this mattress?
The main draw here is peace of mind at a modest price. A 200-night trial gives you more than six months to decide at home, and the 20-year guarantee is longer than most brands offer. The 4cm of memory foam provides pressure relief, which means less build-up around your hips and shoulders if you sleep on your side. The cover has an antibacterial treatment with silver fibres, a sensible touch for allergy-conscious buyers. Yes, at 20cm it is slimmer than some foam mattresses, but the foam base still provides a stable foundation, and the medium/soft feel will suit lighter sleepers and side sleepers well. Delivery within the UK is free, though it typically takes 14 to 28 days.
Key features & layer details
Memory foam
4cm of memory foam in total, which means enhanced cushioning and pressure relief where your body presses in most. You should feel a gentle, contouring hug rather than a firm push-back.
Foam base
A supportive foam base sits beneath the comfort layers to provide a stable foundation. It stops you sinking too far and keeps the mattress feeling consistent edge to edge.

Best suited for?
Side sleepers
The 4cm memory foam layer gives pressure relief, which means less build-up around your hips and shoulders when you lie on your side.
Lighter sleepers
The medium/soft feel suits lighter bodies, which means you can sink into the contouring memory foam without feeling pushed back by a firm surface.
Allergy sufferers
An antibacterial treatment with silver fibres in the cover is a sensible touch if you want a cleaner sleep surface.
Budget buyers
Dormeo describes the appeal as peace of mind at a modest price, backed by a 200-night trial and a 20-year guarantee.
With its medium/soft feel, this is not the mattress for stomach sleepers or heavier bodies who need firmer support to keep the spine level. Hot sleepers should also note that memory foam can retain warmth. And if you want a Small Double or Super King, it only comes in Single, Double and King.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Dormeo Fresh Deluxe mattress?
Dormeo describes it as a medium/soft feel. In practice that means a softer, contouring surface that suits side sleepers and lighter bodies, although back and stomach sleepers who need firmer support may find it a little too giving.
Does the Dormeo Fresh Deluxe come with a trial?
Yes. Dormeo offers a 200-night trial on this mattress, so you can sleep on it at home for more than six months before committing. It also carries a 20-year guarantee, which is longer than most brands offer.
How deep is the Dormeo Fresh Deluxe mattress?
It is 20cm deep, made up of 4cm of memory foam over a supportive foam base. That is slimmer than some foam mattresses, so bear it in mind if you use deep fitted sheets or prefer a taller profile.
How much does the Dormeo Fresh Deluxe cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It comes in UK Single, Double and King. Given the 200-night trial and 20-year guarantee included, it is good value for an all-foam mattress.
Is delivery free on the Dormeo Fresh Deluxe?
Dormeo lists free UK delivery, typically within 14 to 28 days, so it is not a quick turnaround. A delivery charge applies to smaller items on lower-value orders, and extra charges may apply to the Highlands and Islands for some items.
