If you like the classic sink-in memory foam feel at a modest price, this is a sensible shortlist option. The soft firmness and body-moulding foam suit side sleepers and lighter bodies particularly well, easing pressure at the shoulders and hips. The Ecocell® base is designed to be permanently elastic with efficient air circulation, which should temper the warmth memory foam is known for, and the knitted cover is breathable too. The listing states a Dormeo 15 Year Warranty, which is reassuring cover for a mattress starting at £259.00. It is a simple three-layer build, but for the money that simplicity is part of the appeal. Front sleepers and those wanting firm support may find it too soft.

Who's it NOT for?
Dormeo rates this mattress as soft, so it is not the one for sleepers who want a firm, held-on-top feel, and front sleepers may find their hips dip a little too far. At 20cm deep it is also slimmer than some may expect, which heavier sleepers should bear in mind.

How firm is the Dormeo Memory Deluxe mattress?
Dormeo rates it as soft. The memory foam layer moulds to your body, so you sink into the surface rather than lying on top of it. That suits side sleepers and lighter bodies well, although anyone who prefers firm support may find it a little too yielding.
Does the Dormeo Memory Deluxe come with a warranty?
The mattressnextday.co.uk listing states a Dormeo 15 Year Warranty, which is generous cover for a mattress at this price. The page does not state trial nights or a specific return period, so check the terms with your retailer before ordering.
Is the Dormeo Memory Deluxe good for hot sleepers?
Memory foam has a reputation for warmth, but this model works against that in two ways: a breathable knitted cover and an Ecocell® base with a 3 dimensional cellular structure designed for efficient air circulation. Very hot sleepers may still prefer a sprung mattress, though.
How much does the Dormeo Memory Deluxe cost?
Prices run from £259 to £359 depending on size, starting at £259.00. It is available in UK Single, Double and King. For a memory foam mattress with a 15-year Dormeo warranty listed, that is honest value at the affordable end of the market.
Is the Dormeo Memory Deluxe hypoallergenic?
Yes. The listing states it is hypoallergenic, vegan friendly and treated with Sanitized® protection, and it meets the BS7177: 2008 fire resistance standard at low hazard. That combination makes it a reasonable pick if allergies are a concern.
