Layer Details
Knitted cover
A soft, micro-quilted cover that locks the fillings in place and adds a cosy, warm finish. It's infused with Eco Fibre and a 100% natural probiotic Bio Protect treatment.
Gel Foam
A breathable layer with 2cm of gel-infused latex, designed to sleep cooler than traditional memory foam. It provides pressure relief, which means less build-up of tension at your hips and shoulders.
Latex
A plush, adaptive material that responds to your body shape. In practice, this gives a contouring feel without the slow sink of memory foam.
Mini Pocket Springs
800 small, individually cased springs that respond to your shape and movements. They add a layer of soothing pressure relief between the comfort foams and the main support unit.
Pocket Springs
A supportive base of 1,600 Posturepocket springs, each encased in its own cloth pocket. Because they move independently, one sleeper shifting shouldn't disturb the other.

Key benefits
- Room for two in a normal bedroom: At 135 x 190cm, the UK double fits the sort of room most UK homes have, leaving space for drawers and a wardrobe alongside.
- Less disturbance from a restless partner: The 1,600 Posturepocket springs are each in their own pocket, which means one of you shifting in the night shouldn't jolt the other awake.
- A cooler surface when you share: Two bodies generate more warmth, so the 2cm gel-infused latex layer, designed to run cooler than traditional memory foam, helps where it counts.
- Support that adapts to two different bodies: The 800 mini springs react to each sleeper's shape separately, so a heavier and a lighter partner are each supported where they press.
- Easy bedding: Double sheets and a 200 x 200cm double duvet are sold almost everywhere, so dressing this bed never means a special order.
This size suits you if...
You share the bed with a partner and your bedroom is a typical UK size rather than a generous one, or you sleep alone but like to stretch out with a dog or cat at your feet. It also suits a guest room where visiting couples need a comfortable, supportive night.
Consider another size if...
You sleep alone in a compact room where every centimetre of floor counts. We'd recommend the UK single instead, and we suggest at least 2.1m x 2.8m for the UK single.

FAQ's
Is the Relyon Repose Gel Fusion 2400 UK double wide enough for two people?
The UK double gives each of you 67.5cm, which most couples find workable. The independently pocketed springs help, because a partner rolling over is less likely to disturb you. One owner reported the edge support falls a little short, so if you tend to sleep close to the side, bear that in mind.
What are the Relyon Repose Gel Fusion 2400 UK double dimensions in feet?
The UK double is 4ft 6in x 6ft 3in, or 135 x 190cm. It is 32cm deep, so check your fitted sheets have deep enough pockets before you buy, as shallower sheets can struggle to grip the corners.
How much bigger is the Relyon Gel Fusion 2400 double than the single?
The UK double is 45cm wider than the UK single, and the two are the same length. That extra width is what turns a one-person bed into one two people can share, while the length stays the same for both.
Will a UK double Relyon Repose Gel Fusion 2400 fit in a small bedroom?
We suggest allowing at least 2.6m x 2.8m for a UK double, with around 3m x 3m being the comfortable norm. Below that, you may lose room for a bedside table on each side, which couples tend to miss quickly.
Is the Relyon Repose Gel Fusion 2400 double a good choice for a guest room?
For most visiting couples, yes. The medium firm feel suits back and combination sleepers, although lightweight side sleepers may find it slightly firm. A UK double also leaves space for guests' luggage in a second bedroom, and double bedding is easy to find.
