The MattressNextDay Luxury Support Foam Mattress comes in five sizes from UK Single up to Super King. It pairs reflex foam with high-density advanced foam, which means a supportive, slightly firmer feel rather than the deep sink some memory foam gives you. It arrives rolled and boxed with free next day delivery, and comes with a 5-year guarantee. It's a straightforward, sensibly priced option if you want firm-leaning foam support without paying for features you won't notice.

Why should you choose this mattress?
This sits at the affordable end of the foam market, and the spec is good for the money. The medium firm feel comes from reflex foam, which conforms to your body while keeping your spine aligned, so it suits back sleepers and anyone who finds softer foam mattresses leave them sinking. The knitted cover is breathable, which helps keep your temperature steadier through the night, a common worry with foam. It's hypoallergenic, vegan friendly and made in the UK, with a 5-year guarantee behind it. It's a simple two-layer build, but if you want dependable support rather than plush layers, that simplicity is rather the point.

Reflex Foam
Reflex foam conforms to the shape of your body, which means you get tailored support where you need it. It's designed to help your spinal alignment and posture, giving a comfortable, supportive night's sleep.

Best suited for?
Back sleepers
Reflex foam conforms to your body while keeping your spine aligned, which means a supportive medium firm feel that suits lying on your back.
Budget buyers
Sitting at the affordable end of the foam market, this gives you a good spec for the money without paying for extras you would not notice.
Warm sleepers
The breathable knitted cover lets heat escape rather than build up, which helps keep your temperature steadier through the night, a common worry with foam.
Allergy sufferers
A hypoallergenic build means this foam mattress is a sensible pick if you want bedding that avoids common irritants.
Eco-conscious buyers
Being vegan friendly and made in the UK gives you a simple, locally produced foam mattress without animal-derived materials.
If you love a soft, cradling memory foam hug, this medium firm feel may be a little too solid for you. At 20cm it's shallower than many hybrids, so if you prefer a tall, hotel-style mattress, or you want springs for a more responsive feel, look elsewhere.
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.

It arrives rolled and boxed with free next day delivery. Owner reviews mention the boxed format makes it easy to move to the bedroom before unrolling.
