Layer Details
Cover
A breathable Belgian damask fabric cover. It lets air move through the sleep surface rather than trapping heat against you.
Comfort Fillings
Generous layers of British Cheviot wool, prized for its fine, soft properties. Wool breathes naturally, which means it helps keep you at a comfortable temperature year round.
Support System
2000 zoned pocket springs, each mounted in its own separate fabric pocket so they work completely independently. This gives targeted pressure relief and means one sleeper's movement is less likely to disturb the other.

Key benefits
- Leaves room for everything else: At 90cm wide, the UK single fits beside a wardrobe and a desk, so a child's room can still have space for play and storage.
- Wool that suits warm bedrooms: The Cheviot wool fillings breathe naturally, which means a teenager in a small, stuffy box room is less likely to wake up overheated.
- Firmer support for growing bodies: Rest Assured markets this as its firmer version, which suits heavier-built teens and back sleepers better than lighter children who prefer something to sink into.
- Works as a spare room bed: In a study that becomes a guest room a few nights a year, the UK single keeps the desk usable and still gives visitors a substantial, well-filled mattress.
- Pairs well for twin guest rooms: Two UK singles side by side let guests who aren't couples sleep separately, and each sleeper's movement stays on their own mattress.
This size suits you if...
You're buying for one sleeper, perhaps a child or teenager who has outgrown something softer, or you're furnishing a compact spare room or study where a double would crowd the desk. It also suits a first flat or student room with a single frame already in place.
Consider another size if...
You share the bed with a partner, or already find a 90cm width cramped on your own. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

FAQ's
Is the Rest Assured British Wool 2000 single too deep for a cabin bed or mid sleeper?
It may be. The mattress is 36cm deep, and many cabin beds, bunks and mid sleepers set a maximum mattress depth so the guard rail stays high enough to be safe. Check the frame maker's stated limit before ordering. If the rail would end up too low, a slimmer mattress for that frame is the safer choice.
What room size do I need for a UK single Rest Assured British Wool 2000?
We suggest allowing at least 2.1m x 2.8m. That leaves space to walk around the bed and open a wardrobe. In a box room or a loft conversion with a sloping ceiling, measure where you'll actually stand to get in and out, as the flat floor area can be a little smaller than it looks.
Is the Rest Assured British Wool 2000 in a UK single a good choice for a guest room?
It suits guests who like a firmer feel, and the wool helps in spare rooms that get warm. The catch is firmness: a lightweight guest who prefers a soft bed may find it a little solid. If you often host couples, a UK double of the same mattress would serve them better.
Should I get the UK single or UK double Rest Assured British Wool 2000 for a teenager?
The UK single is 45cm narrower than the UK double, and both are the same length. If the room is small and the teen sleeps alone, the UK single keeps floor space free. The UK double needs at least 2.6m x 2.8m, so only choose it if the room can take that comfortably.
How much bigger is the UK king Rest Assured British Wool 2000 than the single?
The UK single is 60cm narrower and 10cm shorter than the UK king. That extra length matters for tall adults, as the UK single's 190cm can feel short for someone well over six foot. The UK king needs at least 2.7m x 2.9m, so it's a very different room commitment.
