Assessed from MattressNextDay's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
At £199 to £299, this is one of the more affordable ways to get a proper memory foam mattress, and the value case is straightforward. The recycled EcoFoam® base moulds to your body's warmth, which means pressure relief where your shoulders and hips need it, while the Reflex Foam layer keeps things supportive rather than sinky. If you sleep on your back and want orthopaedic-style spinal support, the medium firm feel should suit you well. It's hypoallergenic and vegan friendly, made in the UK, and fire resistant to BS 7177. Free next day delivery is a genuine bonus if you need a mattress quickly. The 5-year guarantee is shorter than some brands offer, but it's reasonable at this price.
Key Features & what's inside
- EcoFoam®. A thick layer of 100% recycled and re-engineered foam that responds to your body's natural warmth, moulding to your shape. In practice this means pressure relief exactly where you need it, at your hips and shoulders.
- Reflex Foam. A firm supportive layer that gives the mattress its medium firm feel, which means your spine stays aligned rather than dipping. It's what provides the orthopaedic-style support.
- Memory Foam. A final cushioning layer of memory foam sits nearest to you. It adds a snuggly, softer surface feel over the firmer core.

Who's it NOT for?
If you prefer a plush, sink-in feel, the medium firm support here may feel a little too solid, particularly for lightweight side sleepers. Hot sleepers should also think twice, as all-foam designs tend to retain more warmth than sprung mattresses. And at 20cm deep, it's slimmer than some deep-fill designs.
MattressNextDay Classic Memory Foam Mattress
How firm is the MattressNextDay Classic Memory Foam Mattress?
It's medium firm. The Reflex Foam layer provides firm orthopaedic support for spinal alignment, while the top layer of memory foam softens the surface feel. Some owners report it feels firmer than expected, so if you like a plush mattress, this may not be the one.
How deep is the MattressNextDay Classic mattress?
It's 20cm deep, made up of three foam layers: recycled EcoFoam®, Reflex Foam and a top layer of memory foam, all wrapped in a soft knitted cover that's machine washable.
Does the MattressNextDay Classic come with a guarantee?
Yes, it comes with a 5-year guarantee from MattressNextDay. That's shorter than some brands offer, but reasonable given the mattress starts from £199.
Is the MattressNextDay Classic mattress suitable for allergy sufferers?
Yes, it's certified hypoallergenic, and it's also vegan friendly. It's made in the UK by an NBF-approved manufacturer and is fire resistant to the BS 7177 domestic flammability standard.
What sizes does the MattressNextDay Classic come in?
It's available in UK Single, Double and King sizes, priced from £199 to £299. Delivery is free next day to mainland UK, although some addresses may incur a small fee.
