Layer Details
Knitted cover
A soft, micro-quilted knitted cover infused with Eco Fibre and a 100% natural probiotic Bio Protect treatment, which means the fillings stay secure and the surface feels cosy rather than crunchy. It adds a touch of warmth to the sleep surface.
Gel Foam
A gel foam layer that is more breathable and cooler than traditional memory foam, which means you get the pressure relief without the heat build-up. It cushions aches and pains as you settle in.
Latex
A 2cm layer of gel-infused latex that adapts to your body shape, which means comfort that feels tailored rather than one-size-fits-all. Latex is naturally responsive, so it springs back quickly when you change position.
Pocket Springs
1600 Posturepocket springs, each encased in its own cloth pocket, which means every spring moves independently and support is distributed to each part of your body. This also helps limit motion transfer across the bed.

Key benefits
- Built for sharing in a modest room: At 135 x 190cm it gives two people space to share while leaving floor space that a wider bed would take up in a typical bedroom.
- Less disturbance at close quarters: With 67.5cm each you sleep near your partner, so the 1600 independently moving springs matter more here, limiting how much of their tossing and turning reaches you.
- Cooler when you're sharing body heat: Two people on a UK double warm the bed faster, and the gel foam and gel-infused latex are designed to draw that heat away rather than trap it.
- Room for bedside tables: We suggest at least 2.6m x 2.8m, with around 3m x 3m comfortable, which in many rooms leaves space for a bedside table on each side.
- Easy to dress: Double sheets and a 200 x 200cm double duvet are stocked almost everywhere, so you won't need to hunt for bedding.
This size suits you if...
You share the bed every night in a room of average size and want a proper couples' bed without the frame crowding out your wardrobe, or you sleep alone and like room to stretch out, even with a cat or dog settled in one corner.
Consider another size if...
You and your partner both sprawl, or one of you is broad-shouldered and already feels cramped at 67.5cm each. This mattress is currently listed in UK double only, so a wider bed would mean looking at a different model.

FAQ's
Is the Relyon Gel Fusion 1600 UK double big enough for two people?
For most couples, yes. It gives 67.5cm each, which is close but comfortable for two average-sized adults who don't sprawl. The pocket springs move independently, so you should feel less of your partner's movement than on an open-coil mattress of the same width. A UK king would give 7.5cm more each, although this model isn't currently listed in that size.
What size room do I need for a Relyon Gel Fusion UK double?
We suggest at least 2.6m x 2.8m. That fits the bed with space to walk around it. If you want a bedside table on each side and a wardrobe you can open fully, around 3m x 3m is more comfortable. In a smaller second bedroom, measure the wall where the headboard will go before you order.
How big is the Relyon Repose Gel Fusion 1600 double in feet and inches?
The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. That is the standard British double, so it will fit a standard double bed frame or divan base without gaps at the sides or foot.
Will standard double fitted sheets fit the Relyon Gel Fusion 1600?
Double fitted sheets are the right size for its 135 x 190cm footprint. The mattress is 27.5cm deep, so check the sheet's pocket depth before buying, because some shallow budget sheets can pull tight at the corners. A 200 x 200cm double duvet covers two sleepers comfortably.
Is the Relyon Gel Fusion 1600 double a good choice for a guest room?
It suits a guest room that has to host visiting couples, because a UK double sleeps two without taking over a small spare room. The medium firm feel will suit most back and combination sleepers. Lightweight guests who sleep on their side may find it a little firm at the shoulder.
