Assessed from MattressNextDay's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you want the contouring, cradled feel of memory foam without a premium price, this is a sensible shortlist option. The foam moulds to your shape, which means pressure points at your hips and shoulders get more relief than a traditional sprung mattress would give. The knitted cover is breathable, which helps offset memory foam's usual tendency to hold warmth, though genuinely hot sleepers may still find foam warmer than springs. At 25cm deep it has more substance than many budget foam mattresses. The 5-year guarantee is shorter than some brands offer, but next day delivery is a real advantage if you need a mattress quickly. Certified fire resistant to the BS7177: 2008 standard and made in the UK.
Key Features & what's inside
- Memory Foam. Memory foam, originally designed by NASA, moulds to your body, which means your weight is spread evenly and pressure eases at your hips and shoulders. The brand describes the support as orthopaedic, meaning it aims to keep your spine in a comfortable position as the foam contours.
- Knitted Cover. A soft knitted cover sits on top, and it's breathable, which helps keep you at a more even temperature through the night. That matters with memory foam, which can otherwise feel a little warm.

Who's it NOT for?
If you sleep hot, memory foam holds more warmth than springs, breathable cover or not. Owner feedback mentions a firmer feel than expected and a lingering synthetic smell, so if you're sensitive to off-gassing or want a plush, sink-in surface from night one, look elsewhere. Fans of a bouncy, sprung feel won't find it here.

How firm is the MattressNextDay Deluxe Memory Foam Mattress?
It's rated medium by the brand. That said, owner feedback on the brand's site mentions it feels firm at first and may need an adjustment period, which is common with memory foam as it softens slightly with body heat and use.
How deep is the MattressNextDay Deluxe Memory Foam Mattress?
It's 25cm deep, which is a reasonable depth for a memory foam mattress and means standard fitted sheets should fit without trouble.
Does the MattressNextDay Deluxe Memory Foam Mattress come with a guarantee?
Yes, it comes with a 5-year guarantee from the brand. That's shorter than some mattress brands offer, but not unusual at this price point.
Is the MattressNextDay Deluxe Memory Foam Mattress good for allergies?
It's listed as hypoallergenic, and memory foam generally offers less of a home for dust mites than traditional fillings. It's also vegan friendly, so it contains no wool or other animal-derived materials.
How quickly can the MattressNextDay Deluxe mattress be delivered?
The brand offers free next day delivery to mainland UK, although some addresses may incur a small fee. If you need a mattress in a hurry, that's quicker than most brands manage.
