Key benefits
- Fits where bigger beds won't: At 3ft x 6ft 3in, the UK single leaves room for a desk and wardrobe in a child's bedroom, so the bed isn't eating the whole floor.
- Cooling for one warm sleeper: The cool-to-touch cover and airflow layers are aimed at hot sleepers, which suits a teenager or solo adult who kicks the duvet off most nights.
- Pick the feel per bed: Soft, Medium and Firm are all offered, so if two siblings sleep in separate UK singles, each mattress can be chosen to suit the child using it.
- Simple, easy bedding: Standard single sheets and a single duvet at 135 x 200cm fit the UK single, and these are the most widely stocked bedding sizes in the UK.
- Room for a walkway: Two UK singles side by side in a shared children's room still leave a gap between them, where one double would push the beds hard against the walls.
This size suits you if...
You sleep alone in a small bedroom and run hot at night, or you're furnishing a teenager's room where the bed has to share space with a desk and storage, and you'd rather spend on how the mattress sleeps than on extra width.
Consider another size if...
You share the bed with a partner most nights, as 90cm leaves no real room for two. We'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m.

FAQ's
Will the Brook + Wilde Ultima single fit a bunk bed or mid sleeper?
The width and length match a standard UK single frame, but Brook + Wilde doesn't publish a depth for this mattress. Raised frames usually set a maximum mattress depth so the guard rail stays effective, so check your frame's limit and ask the retailer for the depth before you buy for a bunk, cabin or mid sleeper.
How much bedroom space do I need for a single Ultima mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That gives room to walk round the bed and open a wardrobe, which matters most in a child's room or a spare room that also holds a desk.
Is a UK single Ultima long enough for a tall adult?
The UK single is 190cm long, which is 10cm shorter than the UK king and UK super king. If you're tall and your feet already reach the end of a standard bed, a single may feel cramped lengthways as well as across. A shorter adult sleeping alone will usually find the length fine.
What size sheets and duvet fit the Ultima single?
Standard single sheets fit the 90 x 190cm surface, and a single duvet measures 135 x 200cm. Because Brook + Wilde doesn't publish a depth here, check the fitted sheet's pocket depth against the mattress once it arrives, as a thick mattress can pull shallow sheets off the corners.
Is the Brook + Wilde Ultima single a good choice for a guest room?
It can be, especially in a guest room that sleeps two friends in a pair of singles. Bear in mind that this is a premium, cooling-focused mattress, so it suits a well-used guest room better than one that sees occasional visitors.
