Layer Details
- Advance e-Fibre™. These comfort layers have a breathable cell structure that improves air flow and helps moisture evaporate, which means a cooler, drier sleep surface through the night. It's a fibre-based alternative to foam, so hot sleepers tend to get on with it.
- Open coil spring core. A deep sprung core, with 325 springs in the king size, distributes support evenly across the mattress. Open coil gives a gently springy, traditional feel rather than the contouring you'd get from pocket springs.

- The classic shared size: At 135 x 190cm, the UK double gives couples a familiar amount of shared space without dominating an average bedroom.
- Room for bedside tables: Because a UK double is 15cm narrower than a UK king, most rooms can still take bedside tables on both sides.
- Cooler for two: Two bodies raise the temperature under the duvet, so the breathable Advance e-Fibre comfort layers matter more in a shared size than a single.
- Easy to get upstairs: It arrives rolled, which makes a real difference with a double in an older terrace with a turning staircase or a tight new build landing.
- Simple to dress: Double sheets and duvets are sold everywhere at every price, useful if you're kitting out a guest room on a budget.
This size suits you if...
You share the bed most nights and want the traditional couples' size rather than paying for width you don't have room for, you're furnishing a guest room that needs to sleep visiting couples comfortably, or you sleep alone and want space to spread out, perhaps with a pet claiming a corner. Your room should measure at least 2.6m x 2.8m.
Consider another size if...
You're a couple with the floor space to go bigger, especially as open coil springs carry a partner's movement across the mattress. The UK king would suit you better; allow at least 2.7m x 2.9m for it.

Is the Jay-Be Ryze Comfort double big enough for a couple?
For most couples, yes. The UK double gives you 67.5cm each for two people sharing, which has been the British standard for generations. One caveat with this particular mattress: its open coil core transfers more movement than pocket springs would, so if one of you is restless, the extra width of a UK king helps.
Will a double Jay-Be Ryze Comfort fit in my bedroom?
We suggest a room of at least 2.6m x 2.8m for a UK double, which leaves space to walk round the bed and open drawers. If you want bedside tables on both sides, a little more width is welcome. Most UK bedrooms manage this comfortably, which is a large part of the double's appeal.
Should I get the Jay-Be Ryze Comfort in a double or a king?
The UK double is 15cm narrower and 10cm shorter than the UK king, so the king suits taller sleepers and couples who value elbow room. It also asks more of your room: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double. Measure first, then decide.
Is the double Jay-Be Ryze Comfort easy to get up a narrow staircase?
Easier than most doubles. It arrives rolled and compressed, so it moves through tight turns and narrow landings far more readily than a flat traditional mattress of this size would. Once it's in the room, unroll it on the bed base and let it expand.
What bedding fits the Jay-Be Ryze Comfort in a double?
Standard UK double sheets and a 200 x 200cm double duvet. At 21cm deep, the mattress is slimmer than many, so ordinary fitted sheets will tuck under without straining, and you won't need the extra-deep versions some thicker mattresses demand.
