Layer Details
- Cover. A sumptuously soft natural cover designed for enhanced breathability, which means heat can escape rather than build up around you. It also carries an antibacterial finish.
- Comfort layers. Deep polyester comfort layers sit beneath the cover. These provide the cushioning you feel first, softening the firm springs slightly at the surface.
- Springs. The support core uses individually wrapped pocket springs, 800 of them in the king size. Each spring moves independently, which means less disturbance when a partner turns over.

- A slim build that suits raised frames: At 21cm deep, the Harewood sits comfortably within the depth limits most bunk, cabin and mid sleeper frames impose, where a chunkier mattress would ride above the guard rail.
- Firm support for growing sleepers: The firm tension pocket springs give children and teens a stable, supportive surface, with polyester comfort layers softening the feel slightly at the top.
- Leaves room to live around it: At 3ft wide, this size leaves floor space for a desk, wardrobe and toy storage in a child's room, or a proper walkway between two beds where siblings share.
- Sensible for spare rooms: In a spare room doubling as an office, the UK single keeps the desk end usable while still giving guests a full-length 190cm bed.
- An antibacterial cover for shared use: The soft-touch damask cover carries an antibacterial finish, a reassuring detail for a guest bed or a child's mattress that gets heavy use.
This size suits you if...
You're buying for a child or teenager moving up from a cot or toddler bed, you need a mattress slim enough for a bunk or mid sleeper, or you're kitting out a guest room or student flat where the frame is already a UK single. It also suits a solo adult in a compact room, provided you get on with a firm feel.
Consider another size if...
You're an adult who sleeps diagonally or simply wants more width than 90cm allows. We'd recommend the Harewood in a UK double instead; allow at least 2.6m x 2.8m of floor space for it.

Will the Harewood UK single fit a bunk bed or mid sleeper?
In most cases, yes. At 90 x 190cm it matches the standard UK single frame size, and its 21cm depth sits below the maximum most bunk and cabin beds allow, so the guard rail still does its job. Check your frame's stated depth limit before ordering, as a few budget frames specify shallower mattresses.
Is the Harewood single a good mattress for a child?
It's a reasonable fit for children and teens. The firm pocket springs give a stable surface for growing bodies, and the antibacterial cover finish is a sensible touch. One caveat: very light children who sleep on their side may find the firm tension a little unyielding at the shoulder and hip.
What room size do I need for the Harewood in a UK single?
We suggest at least 2.1m x 2.8m of floor space. That's our guidance rather than the manufacturer's, and it allows room to walk around the bed and open drawers. In a loft conversion or box room, the 90cm width usually leaves space for a wardrobe or desk along the opposite wall.
How much smaller is the single Harewood than the double?
The UK single is 45cm narrower than the UK double, and the two are the same length at 190cm. If you're weighing them up for an adult, that extra width is significant for comfort, but the UK double needs a room of at least 2.6m x 2.8m.
Can two Harewood singles go in one guest room?
Often, yes, and it's a flexible arrangement for a guest room that hosts different combinations of visitors. Each mattress needs 90 x 190cm plus a walkway between the two beds, so measure your room with that gap in mind. The pocket springs also mean each sleeper feels their own bed, not the other's movement.
