Assessed from MattressNextDay's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
At £229 to £379 depending on size, this sits firmly in budget territory, which means you're getting a straightforward supportive foam mattress rather than anything elaborate. If you prefer a firmer surface, perhaps for back support or because you sleep on your back or front, the firm feel here should suit. The recycled EcoFoam® base is a genuinely nice touch at this price, and the certifications, including BS 7177 domestic fire resistance and vegan friendly status, are reassuring. Yes, 19cm is on the shallower side, but that's typical of foam mattresses at this level, and the memory foam top layer adds a little cushioning so it shouldn't feel unyielding.
Key Features & what's inside
- EcoFoam®. A deep base layer of sustainable EcoFoam®, made from 100% recycled and re-engineered foam, which means a sturdy foundation that encourages spinal alignment and posture control. It's the layer doing most of the supportive work.
- Reflex Foam. A firm Reflex Foam layer that moulds to your body shape, which means pressure relief targeted where you actually need it. It bridges the gap between the solid base and the softer surface.
- Memory Foam. A final cushioning layer of memory foam that adds a sumptuous softness at the surface. It takes the edge off the firm feel without undermining the support beneath.

Who's it NOT for?
If you like a soft, sink-in surface, this is probably too firm for you, and lightweight side sleepers may find it presses a little on shoulders and hips. Hot sleepers should note it's all foam with no listed cooling features. At 19cm deep, it's also shallower than some prefer.
