Key benefits
- Leaves room for everything else: We suggest at least 2.1m x 2.8m of floor space, which means a desk and a wardrobe can share a small child's bedroom with the bed.
- Two beds for guests who don't share: A pair of UK singles in a spare room gives friends or siblings visiting at Christmas their own extra firm surface and their own bedding.
- Level support for back sleepers: Eco ComfortCore foam holds up the hips and lower back, which means a teenager who sleeps on their back stays level instead of dipping at the middle.
- Cool start in a snug room: The graphite foam top feels cool to the touch, a small comfort in a compact bedroom or study that warms up quickly on summer evenings.
- Edges you can use: On a 90cm-wide bed you spend more of the night near the sides, so the UniCased edge support system, designed to keep the edges supportive, matters a little more here.
This size suits you if...
You sleep alone, mostly on your back, and want a flat surface that doesn't let you sink in, or you're fitting out a compact child's or teenager's room where a desk has to fit too, or you want two beds in a spare room for guests who sleep separately.
Consider another size if...
You share the bed most nights, or you'd like more length than 190cm. We'd recommend the UK king instead: it gives 75cm each for two sharing, is 10cm longer, and we suggest at least 2.7m x 2.9m.

FAQ's
Will the Sealy Denison UK single fit a bunk bed or mid sleeper?
Possibly, though it's a deep mattress at 28cm. Raised frames usually set a maximum mattress depth so the guard rail stays high enough above the sleeper, so look up that figure from the frame maker before ordering. If 28cm is within the limit, compare the retailers listed on this page.
Is a UK single Sealy Denison suitable for a child?
It can suit an older child or teenager who sleeps on their back and likes a solid, flat feel. It's rated extra firm, though, and lighter side sleepers may find it too unyielding at the shoulders and hips. A young child who curls up on their side may be more comfortable on something gentler.
How big a room do I need for a Sealy Denison single?
We suggest at least 2.1m x 2.8m. That's enough for the bed plus space to walk around it and open a wardrobe door, which is why a UK single works in box rooms, studies and children's bedrooms where a UK double would crowd everything else out.
What sheets and duvet fit the Sealy Denison UK single?
Standard single sheets and a single duvet (135 x 200cm) fit the 90 x 190cm surface. The 28cm depth is the part to watch: choose a fitted sheet that states it suits mattresses of at least that depth, or the corners may keep pinging off.
UK single or UK double Sealy Denison for a spare room?
If your guests are usually couples, the UK double is the better choice, giving 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for it. If your visitors are more often children, friends or relatives who sleep separately, two UK singles give everyone their own bed.
