Layer Details
- Sleep surface. A naturally hypoallergenic fabric that's soft against the skin. A gentle starting point, particularly if allergies bother you at night.
- Comfort Breathe®. These fibres are 15x more breathable than standard memory foam, which means air moves through rather than trapping heat. If you're a hot sleeper, this is the layer doing the heavy lifting.
- 2000 Mirapocket springs. Each spring sits in its own pocket and responds independently to your movements. That gives zoned support and better spinal alignment, and it limits motion transfer between partners.
- Protective Layer. This layer disperses pressure from the spring unit across the mattress. In practice, that should help the mattress last longer before it starts to sag.
- Durable case. A soft, hardwearing outer case designed to keep the mattress comfortable for years to come.

- Fits most UK bedrooms: At 135 x 190cm, this size leaves room for a wardrobe and drawers where a UK king would crowd the walls.
- Made for sharing: You get 67.5cm each for two people sharing, and the 2000 Mirapocket springs limit motion transfer when one of you turns over.
- Cooler for two: Two bodies mean more heat, so the Comfort Breathe fibres matter more in a shared size, moving warmth away rather than trapping it between you.
- Easy to dress: Double sheets and 200 x 200cm duvets are sold everywhere at every price, useful if you're furnishing a whole home on a stretched budget.
- Room for bedside tables: In a room around 3m x 3m, a UK double usually leaves space for tables on both sides, which a wider size often doesn't.
This size suits you if...
You share the bed and your bedroom sits around the typical UK size, so a UK king would leave you squeezing past the footboard. It also suits a solo sleeper who wants space to spread out, or a pet that claims a corner, and it's the safe pick for a guest room that hosts visiting couples.
Consider another size if...
You're a couple with a bedroom of at least 2.7m x 2.9m and one of you sleeps restlessly, because 67.5cm each can feel snug. We'd recommend the UK king instead, which is 15cm wider and 10cm longer.

Is the Silentnight Comfort Breathe 2000 double big enough for two adults?
Yes, for most couples. The UK double gives 67.5cm each for two people sharing, and the 2000 Mirapocket springs respond independently, so you feel less of your partner's movement. Taller or broader couples, or anyone who sprawls, may prefer the UK king, which is 15cm wider and 10cm longer.
What room size do I need for the Comfort Breathe 2000 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most layouts, bedside tables too. This is our guidance rather than Silentnight's, so measure your own room and doorways before ordering.
Will a UK double Comfort Breathe 2000 fit up the stairs?
It's a sprung mattress rather than a rolled foam one, so it arrives full size, and at 135cm wide with a 31cm depth it needs a clear route. Turning stairs in older terraces and tight new build landings are the usual pinch points, so measure the awkward corner, and the doorframe, first.
Should I get this mattress in a double or a small double?
For two people sharing every night, the UK double is the better pick: it's 15cm wider than the UK small double, and both are the same length. The UK small double suits a solo sleeper in a compact room, where we suggest at least 2.4m x 2.8m of floor space.
What bedding fits the Comfort Breathe 2000 double?
Standard UK double bedding: double fitted sheets for the 135 x 190cm footprint and a 200 x 200cm double duvet. Because it's a deep mattress at 31cm, check the fitted sheet's stated depth before buying. Double bedding is the most widely stocked size in the UK, so choice is broad at every price.
