Assessed from MattressNextDay's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
At £259 to £379 this sits at the affordable end of the foam market, and the spec is honest 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.
Key Features & what's inside
- Knitted Cover. A soft knitted cover that's breathable, which means heat can escape rather than build up around you. It helps keep you at an even temperature through the night.
- 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.

Who's it NOT for?
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.
