Layer Details
Quilted pillowtop
A quilted pillowtop sits on top with an advanced breathable sleep system, designed to prevent overheating through the night. It gives the mattress its immediate soft, cushioned feel.
Refresh Fibres
Vertical Refresh Fibres quickly channel moisture away from your body, which means less of that clammy feeling if you tend to sleep warm. They work through the night to prevent overheating.
British wool and fresh fibres
Layers of British wool are blended with sustainable fresh fibres, arranged horizontally so moisture naturally evaporates through the breathable mesh border. Wool is a natural temperature regulator, so this layer helps in both warm and cool conditions.
Pocket spring support system
Individual pocket springs adjust to your body weight, giving support where you need it. Because each spring moves independently, you get ease of movement and an undisturbed night's sleep, useful if you share the bed.

Key benefits
- Fits compact rooms: At 3ft x 6ft 3in, this mattress needs only around 2.1m x 2.8m of floor space by our guidance, so it works in box rooms and under loft slopes.
- Soft feel suits lighter bodies: The softer build makes sense in a single, because lighter sleepers such as teens sink in enough to actually feel the pillowtop's pressure relief.
- Cooling that helps warm sleepers in small rooms: Refresh Fibres and British wool wick moisture away, useful in compact bedrooms and loft conversions that hold heat through summer.
- A comfortable guest option: The plush surface gives occasional guests a soft, cushioned night, and a UK single leaves room for a desk if the spare room doubles as an office.
- Allergy UK approved: The naturally hypoallergenic build is reassuring in a child's or teenager's room, where dust and allergens tend to gather.
This size suits you if...
You're buying for a child or teenager who sleeps on their side or simply prefers a softer bed, you're a lighter solo adult who wants plush comfort in a compact room, or you're furnishing a spare room that needs one comfortable bed without swallowing the floor space a desk or wardrobe also needs.
Consider another size if...
You share the bed, or you're an adult who finds a UK single leaves you brushing the edge when you turn over. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

FAQ's
Will the Nimbus 2000 in a UK single fit a bunk bed or mid sleeper?
Probably not, and this is worth checking carefully. At 34.5cm deep, this is a tall mattress, and most bunk beds and mid sleepers specify a much shallower maximum so the guard rail still does its job. The footprint of the UK single (90 x 190cm) fits standard frames, but the depth is the sticking point here. Check your frame's maximum mattress depth first.
What room size do I need for a UK single Nimbus 2000?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open drawers or a wardrobe. In a child's room competing with toy storage and a desk, or under the slope of a loft conversion, the 90cm width is what keeps the layout workable.
Is the softer Nimbus 2000 single a good choice for a child or teenager?
For side sleepers and lighter bodies, yes. Lighter sleepers often find firm mattresses unyielding, whereas this softer build lets them sink into the pillowtop enough to get real pressure relief. The Allergy UK approval is a further point in its favour for children's rooms. A heavier teen who sleeps on their front may need firmer support, though.
Is a UK single big enough for an adult on this mattress?
For many solo adults, yes: at 90cm wide and 190cm long it's the standard UK one-person size, and the pocket springs adjust to your body weight individually. Taller or broader adults, or restless sleepers who spread out, may feel confined. In that case the UK double, 45cm wider and the same length, is the sensible step up.
How much smaller is the UK single than the UK small double?
The UK single is 30cm narrower than the UK small double, and the two are exactly the same length. That extra width gives a solo sleeper noticeably more room to stretch out, but it costs floor space: we suggest at least 2.4m x 2.8m for the UK small double, against 2.1m x 2.8m for the UK single.
