Assessed from MattressNextDay's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you're after a straightforward hybrid on a tight budget, this one covers the essentials well. The memory foam top moulds to your body shape, which means pressure relief where you need it, while 1000 pocket springs underneath give medium-firm support that suits most back and combination sleepers. The EcoFoam® layer is recycled and breathable, a small sustainability point that also helps with airflow. Free next day delivery to mainland UK is genuinely useful if your old mattress has given up suddenly. The 5-year guarantee is shorter than some brands offer, but at this price that trade-off feels fair. Available in UK Single, Double and King.
Key Features & what's inside
- Top layer. A body-contouring memory foam layer that moulds to your shape, which means personalised comfort at every point of contact. You'll feel a gentle cradling rather than lying on top of the mattress.
- EcoFoam® layer. A recycled, breathable EcoFoam® layer that lets your heaviest pressure points dip slightly into the surface. This helps position your back properly, and the breathability keeps things a little cooler than solid foam alone.
- Pocket springs. Up to 1000 individually pocketed springs that move independently, which means support targeted to key areas of your body rather than the whole bed shifting when you do. They deliver the medium-firm feel.
- Border. A foam-encapsulated border that maintains the mattress's structure right to the edge. You can spread out and use the full surface without a soft, saggy perimeter.

Who's it NOT for?
At 20cm deep, it's slimmer than premium hybrids, so heavier sleepers may sink through the comfort layers over time. Lightweight side sleepers could find the medium-firm feel slightly too solid for their shoulders and hips. And if you sleep very hot, memory foam, even with a breathable layer beneath, may still feel warm.

Is the Simply Memory Pocket 1000 Hybrid firm or soft?
MattressNextDay describes it as medium-firm with orthopaedic properties. The memory foam top softens the initial feel, while the pocket springs provide the firmer support underneath. It suits most back sleepers, although lightweight side sleepers may find it a little too firm.
How deep is the Simply Memory Pocket 1000 Hybrid mattress?
It's 20cm deep. That's shallower than many hybrids, which keeps the price down, but it does mean less material to absorb weight. Fine for most sleepers, though heavier people may want something with more depth.
How long is the guarantee on the Simply Memory Pocket 1000?
MattressNextDay backs it with a 5-year guarantee. That's shorter than some brands offer, but reasonable given the mattress starts at £199.
How is the Simply Memory Pocket 1000 delivered?
It comes rolled and boxed, with free next day delivery to mainland UK. Owner feedback suggests giving it time to expand: one reviewer said it took 3 days to fully inflate.
Is the Simply Memory Pocket 1000 Hybrid 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 meets the BS 7177 domestic flammability standard.
