Why should you choose this mattress?
The memory foam layer moulds to your shape and is designed to relieve built-up pressure, which helps if you like a bed that hugs you a little. Underneath, the springs respond independently and Silentnight says they isolate movement, so a restless partner is less likely to wake you. There's a firm centre to spread your weight evenly. It's likely to suit most back sleepers and many couples, although lighter side sleepers may find a medium-firm feel a touch unforgiving at the shoulders. The cover is treated with Purotex, which is aimed at allergens, and the 60-night trial gives you time to decide.

Best suited for?
Back sleepers
The medium-firm feel and firm centre spread your weight evenly, so you get some contouring from the memory foam without sinking in too far.
Couples
Independently responding pocket springs, which Silentnight says isolate movement, mean a restless partner is less likely to wake you during the night.
Allergy sufferers
The Purotex cover is treated to combat allergens and dust mite, which gives you a cleaner sleep surface than an untreated cover would.
Budget buyers
Described as affordable, it still packs a memory foam top layer over 1,000 Mirapocket springs, so you get a hybrid build without paying for extras.
If you prefer sleeping on a soft mattress, this might not be the best choice. It's rated medium firm, so the memory foam sits over a fairly supportive base. Lighter side sleepers who want to sink in may find it too firm.
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.
