Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you like a firm base with a little softness on the surface, this design makes sense: the cushion top gives some initial give, which means you get pressure relief at the shoulders and hips without losing the solid support underneath. The Eco Comfort layer uses fibres partially made from recycled plastic, including bottles, and is breathable, so it helps regulate temperature and reduce moisture build-up, useful if you tend to sleep warm. The Miracoil springs offer zoned support and let you sleep right to the edge without feeling like you'll roll off, handy for couples sharing a smaller bed. Priced between £300 and £535 across sizes, it's basic, but sensible value for what's inside.
Key Features & what's inside
- Cushion Top. A deep-filled cushion top stuffed with extra soft fillings, which means a gentler first impression when you lie down. It softens the surface without changing the firm support beneath.
- Eco Comfort Layer. Silentnight's Eco Comfort layer uses fibres partially made from recycled plastic, including bottles. It's breathable and helps regulate temperature and reduce moisture build-up, so you should feel a little less clammy on warm nights.
- Miracoil Spring System. Silentnight's exclusive Miracoil spring system provides zoned support, which means firmer reinforcement where your body carries more weight. It also supports you right to the edge of the mattress, so you can use the full sleep surface without feeling you'll fall off.

Who's it NOT for?
Silentnight labels this mattress Extra Firm, so lightweight sleepers and dedicated side sleepers may find it too unyielding, even with the cushion top. If you want a soft, enveloping memory foam feel, this firm, springy build isn't it. Anyone after a deep luxury mattress may also find 24cm on the shallow side.

Is the Silentnight Miracoil Memory Cushion Top firm or soft?
Silentnight's own product page lists it as Extra Firm, so treat it as a properly firm mattress. The deep-filled cushion top softens the surface a little, but the overall feel is supportive rather than plush. Some retailer listings describe it as Medium Firm, but the brand's own label is the safer guide.
How deep is the Silentnight Miracoil Memory Cushion Top mattress?
It's 24cm deep. That's enough for the cushion top, Eco Comfort layer and Miracoil springs, though it's shallower than some luxury hybrids, so standard fitted sheets should fit without any trouble.
Does the Silentnight Miracoil Memory Cushion Top come with a trial?
Yes, when bought from Silentnight directly it comes with a 60-night trial and a 5-year guarantee. Silentnight also offers delivery within 48 hours (Monday to Friday, excluding Bank Holidays) or within 14 days. Terms may differ if you buy through another retailer.
What sizes does the Silentnight Miracoil Memory Cushion Top come in?
Five UK sizes: Single, Small Double, Double, King and Super King. Prices run from £300.38 up to around £535 depending on the size you choose.
Is the Silentnight Miracoil Memory Cushion Top good for hot sleepers?
It should cope reasonably well. The Eco Comfort layer is breathable and designed to regulate temperature and reduce moisture build-up, and the sprung core allows more airflow than an all-foam design. If you sleep very hot, that combination is a sensible choice at this price.
