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.

- Room left for everything else: At 3ft x 6ft 3in, the UK single leaves space for a desk, wardrobe or toy storage in a child's room, and we suggest allowing at least 2.1m x 2.8m.
- Full support for one: You get all 800 mini pocket springs and 1,600 Posturepocket springs in a one-person width, which means a single sleeper gets the same layered support as someone buying the larger size.
- Cooler for warm sleepers: The gel-infused latex near the surface is designed to run cooler than traditional memory foam, which helps in a small, warm box room or a loft conversion that holds heat.
- Suits a growing teenager: The medium firm feel gives the kind of steady back support older children and teens often need, although a very light child may find it slightly firm at first.
- Fits under a sloping ceiling: The narrow 90cm footprint can tuck under the slope of a loft conversion, although the 32cm depth raises the sleeping surface, so check your headroom before ordering.
- Works as a pair: Two UK singles side by side in a guest room let visiting friends or siblings sleep separately, each on the same supportive hybrid.
This size suits you if...
You sleep alone and want a supportive hybrid in a compact footprint, you're furnishing a child's or teenager's room where the bed shares space with a desk and storage, or you're kitting out a spare room with two separate beds for guests who won't share.
Consider another size if...
You share the bed with a partner, or your bunk or cabin frame only takes slim mattresses. For couples, we'd recommend the UK double instead, and we suggest at least 2.6m x 2.8m for the UK double.

Will the Relyon Repose Gel Fusion 2400 UK single fit a bunk bed or mid sleeper?
It will fit the 90 x 190cm base, but at 32cm deep the mattress is thicker than many raised frames are designed for. A deep mattress reduces how far the safety rail rises above the sleeping surface, so check the frame maker's maximum mattress depth before buying for a bunk, cabin or mid sleeper bed.
What size bedroom do I need for a Relyon Repose Gel Fusion 2400 UK single?
We suggest allowing at least 2.1m x 2.8m for a UK single. That leaves enough floor space for a desk or chest of drawers alongside the bed, which is useful in a child's room or a spare room that also serves as a home office.
Is the UK single Relyon Repose Gel Fusion 2400 a good choice for a child or teenager?
For teenagers and older children it suits well. The medium firm feel and two tiers of pocket springs give steady support through a growth spurt. A younger, very lightweight child may find it slightly firm, particularly if they sleep on their side, so consider who will be sleeping on it.
Can two people share a Relyon Repose Gel Fusion 2400 in a UK single?
Not comfortably. A UK single is 90cm wide, which is intended for one person. If two of you need to share, the UK double is 45cm wider and gives 67.5cm each. We suggest at least 2.6m x 2.8m of floor space for the UK double.
Relyon Repose Gel Fusion 2400 single or double for a guest room?
If your guests are usually couples, the UK double makes more sense. If they're more often friends, siblings or grandchildren sleeping separately, two UK singles give each person their own bed. Both sizes are 190cm long, so choosing between them affects width only. Compare the retailers listed on this page for current availability.
