Layer Details
Advance e-Fibre™
An extra-soft, deep-quilted top layer of Advance e-Fibre, which means a luxurious surface feel the moment you lie down. It also wicks moisture away to help keep the mattress fresh and regulate temperature.
Breathable comfort layers
Open-cell comfort layers let air circulate freely through the mattress. In practice that means a fresher, more ambient sleep environment rather than trapped heat.
3D Mesh ventilated border
The border itself is made from ventilated 3D mesh, which gives warm air an escape route around the sides. It's a small detail that adds to the mattress's overall breathability.
Deep Pocket Sprung core
800 individual pocket springs adapt to your body's contours for tailored support. Because each spring moves independently, motion transfer is reduced, so you're less likely to be disturbed by a restless partner.

Key benefits
- Room for two, space left over: At 135cm wide the UK double leaves space for a wardrobe and bedside tables on both sides in most rooms, which a UK king often doesn't.
- 67.5cm each when sharing: Two people sharing get 67.5cm each, and the 800 independent pocket springs limit how much you feel a partner turning over on their side.
- Cool sleeping matters more in a shared bed: Two bodies produce twice the heat, so the foam-free build and 3D Mesh ventilated border give warmth somewhere to go on close nights.
- Arrives rolled, so tight stairs are less of a worry: It comes vacuum packed and rolled, which helps if you're turning the stairs in an older terrace or squeezing past a tight new build landing.
- The easiest size to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere at every price, useful if you're kitting out a whole home at once.
This size suits you if...
You share the bed most nights and want the traditional couples' size without giving a UK king the whole room, or you sleep alone and like space to stretch out. It also suits a guest room that regularly hosts visiting couples, since the medium feel and reduced motion transfer work for most sleepers without you knowing their preferences in advance.
Consider another size if...
You and your partner both like to sprawl, or one of you is a restless sleeper, and your room measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead, which is 15cm wider and 10cm longer.

FAQ's
What room size do I need for the Jay-Be Ryze in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves enough clearance to open drawers and walk round the bed, and in most rooms it still allows bedside tables on both sides, something a wider size often rules out.
Is the UK double Jay-Be Ryze big enough for a couple?
For most couples, yes. You get 67.5cm each for two people sharing, and because each of the 800 pocket springs moves independently, a restless partner disturbs you less than on a connected-spring bed. If you both spread out in your sleep, the UK king adds 15cm of width and 10cm of length.
Will the Jay-Be Ryze UK double get up narrow stairs?
It should be one of the easier deliveries. The mattress arrives vacuum packed and rolled in a box, so you're carrying a compact cylinder rather than manoeuvring a full 135 x 190cm mattress round a turning staircase or a tight landing. It expands once unrolled in the bedroom.
What bedding fits this mattress in a double?
Standard UK double sheets and a 200 x 200cm double duvet. Because the double is the most common size in Britain, bedding is stocked everywhere at every price point, which keeps costs down if you're furnishing several rooms at once or replacing a worn set on a budget.
Should a solo sleeper size down from the UK double?
Not necessarily. Sleeping alone on a UK double means the full 135cm width to yourself, welcome if a dog or cat claims a corner of the bed. If your room is genuinely tight, the UK small double is 15cm narrower and the same length, and we suggest at least 2.4m x 2.8m for it.
