Layer Details
- Intense™ sleep surface. The top surface, which Silentnight states is scientifically proven to reduce cortisol levels and morning stress brought on by the menopause. In practice, this is the layer aimed at calmer, less disrupted mornings.
- Breathable Sleep System. A layer designed to reduce night sweats by enhancing breathability and moving heat and moisture away from your body. If you tend to sleep hot, this is the part of the build doing the heavy lifting for you.
- Mirapocket® springs. 1600 individual pocket springs that adjust to your body weight, giving zoned, tailored support. Each spring moves independently, which means less motion transfer if you share a bed.
Layer details from silentnight.co.uk product page, September 2026.
- A shared size that suits most rooms: At 135cm wide, the UK double fits bedrooms where a UK king would leave you squeezing past the footboard, so bedside tables on both sides usually stay possible.
- 67.5cm each when you share: Two people sharing get 67.5cm each, enough for most couples, and the 1600 Mirapocket® springs move independently so a restless partner disturbs you less.
- Cooling that matters more when sharing: Two bodies generate more heat than one, and the Breathable Sleep System is designed to move heat and moisture away, which helps if night sweats already wake you.
- Room to allow at least 2.6m x 2.8m: We suggest a minimum room of 2.6m x 2.8m for this size, with around 3m x 3m the comfortable norm for walking space and a wardrobe.
- Easy, affordable bedding: Double sheets and a 200 x 200cm double duvet are sold everywhere at every price point, which keeps ongoing costs down compared with the larger sizes.
This size suits you if...
You share the bed with a partner and your bedroom is a typical UK size, where a bigger bed would crowd the room; you're dealing with menopause-related night sweats and want a shared size with a cooling build; or you sleep alone and want proper room to spread out, perhaps with a pet claiming a corner, without giving over the whole floor to the bed.
Consider another size if...
You and your partner both like space and your room measures well beyond the minimum. The UK king is 15cm wider and 10cm longer than the UK double, and we suggest at least 2.7m x 2.9m for it.

Is the Silentnight Lift Breathe UK double big enough for a couple?
For most couples, yes. Two people sharing get 67.5cm each, and the 1600 pocket springs move independently, so you feel less of your partner turning over. If either of you is broad-shouldered or a sprawler, the UK king adds 15cm of width and 10cm of length, provided your room can take it.
What room size do I need for the Silentnight Lift Breathe double?
The mattress itself is 135 x 190cm. We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows bedside tables on both sides and a clear walkway, which is usually the deciding factor between a UK double and a UK king in an average bedroom.
Should I get the Lift Breathe in a double or a king?
It mostly comes down to your room. The UK king is 15cm wider and 10cm longer, and we'd allow at least 2.7m x 2.9m for it. If you're tall, that extra length is genuinely useful. In a smaller room, the UK double keeps wardrobes and drawers workable, which matters when furnishing a first flat.
Is the Lift Breathe double a good choice for a guest room?
It's a sensible guest room size, since a UK double comfortably takes visiting couples where a UK single wouldn't. The menopause-focused cooling features may go unused by guests, so if the mattress is mainly for occasional visitors, you may be paying for a build designed for a specific problem your guests don't have.
Will a UK double Lift Breathe get up the stairs in an older house?
At 135 x 190cm, a UK double is the largest size that turns tight staircases and narrow landings fairly easily, which is one reason it remains Britain's default couples' size. The pocket spring construction means it shouldn't be folded, so measure the awkward turn in an older terrace or a tight new build landing before ordering.
