Layer Details
- Sleep surface. A naturally hypoallergenic fabric that feels soft against the skin. A gentle starting point for sensitive or allergy-prone sleepers.
- Airloft™ comfort layer. A foam alternative made from lightweight, open non-woven fibres, which the brand says is 18x more breathable. It mimics the feel of countless tiny springs, gently contouring to your body and spreading your weight evenly.
- 1000 Mini springs. A layer of 1,000 mini springs that respond to even slight movements, which means the surface adjusts as you shift in the night. They also add airflow through the middle of the mattress.
- Comfort Breathe®. Fibres described as 15x more breathable than standard memory foam. They promote airflow and help regulate temperature, a real plus if you tend to overheat.
- 600 Mirapocket spring unit. 600 pocket springs held in individual fabric pockets, each responding independently to your body. That gives you zoned support and better spinal alignment, and less disturbance from a restless partner.
- Protective layer. Disperses pressure from the spring unit across the mattress. In practice, this helps the mattress keep its feel for longer.
- Durable case. A soft but hard-wearing outer case designed to keep the mattress comfortable for years.

- Fits the average UK bedroom: At 135 x 190cm the UK double leaves room for furniture where a UK king would dominate, and we suggest a room of at least 2.6m x 2.8m.
- Less partner disturbance in a shared size: The 600 Mirapocket springs respond independently, which means a partner turning over on their 67.5cm of the bed is less likely to wake you.
- Cool sleeping for two: Two bodies raise the temperature under one duvet, so the foam-free Airloft and Comfort Breathe layers, built for airflow, suit couples who run warm.
- Bedside tables on both sides: In a typical double bedroom this width usually still allows a table each side, worth measuring before you commit to anything wider.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere at every price, handy if you're kitting out a home on a spread budget.
This size suits you if...
You share the bed every night and want the traditional couples' size that leaves your bedroom usable, or you sleep alone and like space to spread out, perhaps with a dog or cat claiming a corner. It also makes a sensible guest room bed for visiting couples, and both of you prefer a softer, medium/soft feel to a firm surface.
Consider another size if...
You and your partner both like room to sprawl, or one of you is a restless sleeper, because 67.5cm each can feel snug. We'd recommend the UK king instead, allowing a room of at least 2.7m x 2.9m.

Is the Silentnight Comfort Breathe Plus 1600 UK double big enough for a couple?
For most couples, yes. The UK double is 135cm wide, giving two sharers 67.5cm each, and the 600 Mirapocket springs move independently so you feel less of a partner's shifting. If either of you sprawls or sleeps restlessly, the UK king adds 15cm of width and 10cm of length.
What room size do I need for the Comfort Breathe Plus 1600 in a double?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That allows walking space and, in most layouts, bedside tables on both sides. If your room is smaller, the UK small double is 15cm narrower and needs at least 2.4m x 2.8m.
How big is the Comfort Breathe Plus 1600 in a UK double?
The UK double measures 135 x 190cm, or 4ft 6in x 6ft 3in. It's Britain's standard couples' size, so nearly all double sheets, protectors and 200 x 200cm duvets fit it without hunting for special bedding.
Will a double Comfort Breathe Plus 1600 fit up narrow stairs?
A UK double at 135cm wide is easier to manoeuvre than a UK king, which helps in older terraces with turning staircases or new builds with tight landings. It's still a 28cm-deep sprung mattress though, so measure your stairwell and any awkward corners, and check the brand's own delivery guidance before ordering.
Should I get the Comfort Breathe Plus 1600 in a double or a king?
Choose the UK double if your room is close to the 2.6m x 2.8m minimum we suggest, or you want the widest bedding choice. The UK king is 15cm wider and 10cm longer, better for taller sleepers or couples who want more personal space, and needs a room of at least 2.7m x 2.9m.
