Layer Details
Cover/Fabric
A deep-quilted knitted fabric that's OEKO-TEX certified, which means it has been tested and shown to be free from harmful chemicals. The quilting adds a soft, cushioned surface feel from the moment you lie down.
Comfort Layer
Extra-soft Advance e-Fibre with an open-cell structure that encourages airflow and helps moisture evaporate, so heat is less likely to build up around you. It's made from recycled PET bottles, with a minimum of 70% recycled content.
Support Core
A deep sprung core that provides evenly distributed support across the mattress. Springs respond to pressure more quickly than foam, giving a slightly bouncier, more traditional feel.

Key benefits
- The classic shared size: At 135 x 190cm, the UK double gives two sleepers 67.5cm each, enough for most couples without the bed dominating the room.
- Cooler for two: Two bodies generate more heat than one, and the open-cell e-Fibre comfort layer helps that warmth and moisture escape rather than build up between you.
- Fits typical rooms: We suggest a room of at least 2.6m x 2.8m, which most UK doubles bedrooms meet with space for bedside tables on both sides.
- Easier to get upstairs: Because it arrives rolled in a box, a 4ft 6in mattress can turn the awkward stairs of an older terrace far more easily than a flat-packed sprung double.
- Springy, not sinking: The deep sprung core responds quickly to pressure, so if one of you turns over the other feels a light bounce rather than a slow foam wallow.
- Simple to dress: Standard double sheets and a 200 x 200cm duvet fit, both stocked everywhere at every price point.
This size suits you if...
You share the bed every night and want the traditional couples' size that leaves room for wardrobes and drawers, or you sleep alone and like space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since the medium feel and cooler fibre fillings please most sleepers passing through.
Consider another size if...
You and your partner both like space and your room measures well beyond the minimum, or one of you sleeps hot and restless. We'd recommend the UK king instead, which is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m for it.

FAQ's
Is the Jay-Be Ryze in a UK double big enough for a couple?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, and the sprung core spreads support evenly across the full 135cm width. If either of you is broad-shouldered or a restless sleeper, 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 Jay-Be Ryze 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 plus bedside tables, which matters if you're squeezing a bed, wardrobe and drawers into a first flat or second bedroom. Measure with the door swing and any radiators in mind.
Will the UK double Jay-Be Ryze fit up narrow stairs?
It should manage better than most. It arrives compressed and rolled in a box, so the tight turns of an older terrace or a narrow new build landing are far less of a problem than with a traditional flat sprung double. Once unrolled it expands to its full 135 x 190cm.
Is the Jay-Be Ryze double good for a guest room?
It's a sensible fit. A UK double comfortably sleeps visiting couples, the medium firmness suits a wide range of guests, and the hypoallergenic, foam-free fillings avoid complaints from anyone who dislikes the sink of memory foam. Heavier guests who prefer a firm feel may find it slightly soft.
What bedding fits the Jay-Be Ryze double?
Standard UK double sheets, sized for 135 x 190cm, and a 200 x 200cm double duvet. Because the mattress is a slimmer 21cm deep, you won't need extra-deep fitted sheets, so ordinary ones stay put and cost less. That makes it easy to dress on a budget when you're furnishing a whole home at once.
