Why should you choose this mattress?
The memory foam layer is infused with graphite and Silentnight says it's 15% cooler than standard memory foam, so you get the pressure-easing cushion of foam with less of the stuffy heat. The CoolEase cover is designed to draw heat away from your body, which helps if you tend to overheat at night. Underneath, the Mirapocket zoned support system gives different areas of the body different support. It suits warm sleepers who want foam comfort on a spring base, although with no firmness rating published, the feel is hard to judge in advance.

Best suited for?
Warm sleepers
The graphite-infused memory foam is said to be 15% cooler than standard foam, and the CoolEase cover draws heat away, so you get cushioning with less stuffy warmth.
Combination sleepers
Pocket springs arranged in zones under a memory foam layer give varied support across the body, which suits those who shift positions through the night.
Couples
Individually working pocket springs in a zoned system, plus a size range from UK double to UK super king, give two sleepers room and support.
If you want to know the firmness before you buy, this might not be the best choice, as Silentnight doesn't publish a rating. Anyone who wants a mattress with no foam at all may also be put off, since the comfort layer is memory foam. Depth isn't published either, so check it against your bed frame.
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.
