Why should you choose this mattress?
The firm feel suits back sleepers and anyone who likes to sleep on top of a mattress rather than sink into it. The memory foam is stitched directly onto the surface, which gives a smoother feel than loose layers. Underneath, the zoned Miracoil springs give support without disturbing your partner, which helps if you share a bed. The cover is hypoallergenic and treated with Purotex to reduce moisture and dust-mite allergens. At an affordable level, and with a 60-night trial, it is a low-risk way to try a firm mattress, although lighter side sleepers may find it too unyielding.

Best suited for?
Back sleepers
The firm feel and zoned Miracoil spring system give solid support underneath, so you rest on top of the mattress rather than sinking into it.
Couples
Zoned Miracoil springs give support without disturbing your partner, which helps if you share a bed and one of you moves around in the night.
Allergy sufferers
The hypoallergenic cover is treated with Purotex to reduce moisture and dust-mite allergens, which suits anyone wanting a cleaner sleep surface.
Budget buyers
It is described as affordable, and the 60-night trial means you can try a firm mattress with little risk before committing.
If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It is rated firm, and the memory foam on top is there for a smoother surface rather than deep cushioning. Lighter side sleepers may feel pressure at the shoulders and hips. It is also single-sided, so it can't be flipped.
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.

FAQ's
Is the Silentnight Miracoil Memory soft or firm?
Silentnight rates it firm. That suits back sleepers and anyone who wants solid support, although lighter side sleepers who like a softer, more cushioned feel may find it too firm.
What sizes does the Silentnight Miracoil Memory come in?
It comes in UK Single, UK Small Double, UK Double, UK King and UK Super King. That covers single sleepers and most couples, so you can choose by bedroom space and how much room you want.
How deep is the Silentnight Miracoil Memory?
It is 22.5cm deep. That is a fairly standard height, so it should suit most bed frames, though check your frame and any fitted sheets you plan to reuse.
Does the Silentnight Miracoil Memory come with a trial?
Yes, Silentnight lists a 60-night trial. It also describes a lifetime guarantee, which is free when you register within 3 months of purchase, so make sure you register it in time.
Is the Silentnight Miracoil Memory good for couples?
It can be. The Miracoil zoned spring system is designed to give support without disturbing your partner. The firm feel needs to suit you both, though, so it works best if neither of you wants a soft mattress.
