Layer Details
- Knitted cover. A knitted cover tops the mattress, adding a final soft layer against you.
- Microquilted layer. A micro-quilted finish gives the surface a smooth, soft feel from the first night.
- Soft White Fibres. Soft synthetic fillings sit near the top to create a cosy feel. This is where much of the plushness comes from.
- Memory Foam. Memory foam cradles your shape for a cushioned feel, which means pressure is spread rather than concentrated. It's made with graphite to help disperse body heat.
- Mini Pocket Springs. Small, individually cased springs add a responsive comfort layer with soothing pressure relief.
- Pocket Springs. The main support layer: springs encased in individual cloth pockets that adapt to movement, distributing support to each part of your body.

- Room to live around the bed: At 3ft x 6ft 3in, a single leaves space for a desk and a wardrobe in a child's room, and we suggest allowing at least 2.1m x 2.8m.
- A softer feel for lighter builds: The medium soft surface gives under lighter bodies, which means children, teens and slimmer adults are more likely to feel the cushioning than a firm platform.
- Cooler foam in a small space: The memory foam is made with graphite to help disperse body heat, which helps in a compact bedroom where warm air has less room to move.
- Two singles for flexible guest rooms: A pair of UK singles lets two guests who aren't a couple sleep separately, each on the same plush, sprung surface.
- Fits where the ceiling slopes: The narrow 90cm width can tuck beneath a sloping ceiling in a loft conversion, where a wider bed would push into the lowest headroom.
This size suits you if...
You sleep alone and want a cushioned, sink-in feel, you're furnishing a child's or teenager's room where the bed has to share floor space with storage and a desk, or you're setting up a spare room where two separate beds suit your visitors better than one.
Consider another size if...
You share the bed with a partner most nights, or 90cm feels cramped for how you sleep. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

Will the Sleepeezee Memory Ultimate 9500 single fit a bunk bed or mid sleeper?
The UK single is the right width and length for most bunk, cabin and mid sleeper frames, but this mattress is 36cm deep. Raised frames often set a maximum mattress depth so the guard rail stays high enough to be safe, so check the frame maker's limit before ordering.
What size room do I need for a UK single Memory Ultimate 9500?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open drawers, which matters in a small child's room or a box room also used as a study.
Is the Memory Ultimate 9500 UK single a good mattress for a teenager?
It can be, particularly for a lighter teen who sleeps on their side, as the medium soft feel and memory foam cushion hips and shoulders. A heavier teen or a front sleeper may sink further than is comfortable and would likely do better on something firmer.
Single or small double Memory Ultimate 9500 for a guest room?
The UK single is 30cm narrower than the UK small double and the same length. If your guests usually arrive as couples, the UK small double is the kinder choice, and we suggest at least 2.4m x 2.8m for it. For solo visitors or two separate beds, the UK single fits better.
Is a UK single mattress long enough for a tall adult?
The UK single is 190cm long, which suits most adults. If you're tall enough to find your feet near the edge, the UK king is 10cm longer, though it is also 60cm wider and we suggest at least 2.7m x 2.9m of room for it.
