Silentnight Memory 7 Sleep Mattress

Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.

This mattress suits you if you like the slow, cradling feel of memory foam without a premium price tag. The 30mm memory foam layer responds to your natural heat, which means it gradually shapes to your body and eases pressure on hips and shoulders. Underneath, Miratex foam absorbs movement, so a restless partner is less likely to wake you, and it eliminates roll together, that tendency for two sleepers to drift into the middle. Support extends to the edge of the mattress, useful if you sit on the side to get dressed or sleep near it. Sizes run from UK Single to Super King, plus EU sizes, which is handy if you have a continental bed frame.

Couples
Miratex foam absorbs movement and eliminates roll together, so a restless partner is less likely to wake you and you each stay on your own side.

Side sleepers
The 30mm memory foam layer softens with body heat and moulds around you, which eases pressure on hips and shoulders when lying on your side.

European bed frames
Sizes run from UK Single to Super King and include EU options, so it is easy to find a fit for a continental frame.

Budget buyers
Described as an affordable route into memory foam, it gives you the slow, cradling feel without a premium price tag.

If you're a hot sleeper, be cautious: memory foam responds to body heat and tends to hold warmth more than sprung designs. Anyone who prefers a springy, responsive surface may find the slow-moving foam feel a little too enveloping. And with no firmness rating published, buyers with a strict firmness requirement should check before committing.

Is the Silentnight Memory 7 Sleep mattress memory foam or sprung?

It's an all-foam mattress with no springs. A 30mm memory foam layer sits on top, responding to your body heat and moulding to your shape, with Miratex foam beneath providing support to the edges and absorbing movement between sleepers.
