Why should you choose this mattress?
This mattress makes sense if you want the pressure relief of memory foam without the full sink-in feel of an all-foam bed. The 800 Mirapocket springs respond independently to your movements, which means less disturbance from a restless partner and support that adjusts to different parts of your body. The medium feel is a safe middle ground for most sleepers, and the 60-night sleep guarantee gives you a proper stretch of time to be sure. It is a simple two-layer design, but that simplicity keeps the cost down while covering the essentials of comfort and support.
Key features & layer details
Memory foam
This top layer gently moulds to the contours of your body, which means pressure points at your hips and shoulders get some relief. It provides that cushioned, hugging comfort memory foam is known for.
Mirapocket springs
Beneath the foam, 800 Mirapocket springs respond independently to your body's movements. This gives zoned support and improved spinal alignment, so your back stays in a healthier position through the night.

Best suited for?
Side sleepers
The memory foam top layer moulds to the body, which means your hips and shoulders get some pressure relief when lying on your side.
Back sleepers
A medium feel gives a balanced surface that is neither too soft nor too hard, while the pocket springs support the different areas of your back.
Couples
The 800 Mirapocket springs respond independently, which means you feel less disturbance when a restless partner moves around during the night.
Budget buyers
Sitting at the affordable end of the pocket sprung market, its simple two-layer build keeps costs down while still covering comfort and support.
Guest rooms
A medium feel is a safe middle ground for most sleepers, so visitors with different preferences should find it comfortable enough for a stay.
If you sleep hot, be aware that memory foam can retain warmth, and this model has no stated cooling features. Heavier sleepers or anyone who prefers a firmer, more supportive feel may find the medium tension a little forgiving. It is also a fairly simple build, so those wanting a deeper, more luxurious mattress should look further up the range.
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.
