Assessed from the specification published by Furniture Village, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is breathability at a firm support level. The ActiveBreathe layer is described as feeling like memory foam but ten times more breathable, which means less of that sink-and-swelter sensation hot sleepers dread. Underneath, the Mirapocket® springs respond to each sleeper independently, so a restless partner is less likely to disturb you. An Eternity layer adds stability and long lasting resilience, which should help the mattress keep its shape over time. There's a green angle too: 60% recycled materials, a 100% recyclable design, and Silentnight is a carbon-neutral company committed to net zero by 2040. Furniture Village lists a 20-year guarantee with this mattress, a reassuringly long span as its retailer offer.
Key Features & what's inside
- ActiveBreathe layer. This comfort layer feels like memory foam but is ten times more breathable, which means contouring comfort without the overheating foam is known for. If you tend to sleep warm, this is the feature to pay attention to.
- Mirapocket® spring system. Silentnight's Mirapocket® system uses 800 pocket springs in the king size. Each spring moves independently, so the mattress responds to your shape and reduces the ripple effect when a partner shifts position.
- Eternity layer. The base Eternity layer gives the mattress extra stability and long lasting resilience. In practice, that means the firm feel should hold up rather than softening quickly.

Who's it NOT for?
This is a genuinely firm mattress, so lightweight side sleepers may find it a little too unyielding on the shoulder and hip. If you prefer a plush, sink-in feel, look elsewhere. And if you need your mattress quickly, note that Furniture Village estimates delivery within 21 days, with a £39 charge.
Silentnight Revitalise Refresh 800 Mattress
Is the Silentnight Revitalise Refresh 800 firm or soft?
It's rated Firm. That suits back and front sleepers who want plenty of support, although lighter side sleepers may find it slightly too solid for comfortable pressure relief at the shoulder.
How many springs does the Silentnight Revitalise Refresh 800 have?
The Mirapocket® system contains 800 pocket springs in the king size. The count for other sizes, including super king, isn't specified on the listing we've seen.
Does the Silentnight Revitalise Refresh 800 sleep hot?
It's designed not to. The ActiveBreathe layer feels like memory foam but is described as ten times more breathable, so hot sleepers should find it noticeably airier than a traditional foam-topped mattress.
What guarantee comes with the Silentnight Revitalise Refresh 800?
Furniture Village lists a 20-year guarantee with this mattress. That's the retailer's own offer, so check the terms with whichever shop you buy from, as guarantees can differ between sellers.
How deep is the Silentnight Revitalise Refresh 800?
It's 27.5cm deep, a fairly substantial profile. Standard fitted sheets should still work, but if yours are shallow it's sensible to check before buying.
