Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
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. Priced from £285 to £525 across sizes from UK Single to Super King, it is a simple two-layer design, but that simplicity keeps the cost down while covering the essentials of comfort and support.
Key Features & what's inside
- 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.

Who's it NOT for?
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.
