Layer Details
Pillow top
A cloud-like pillow top with an additional layer of adaptive memory foam and mini pocket springs, which means a soft, cushioned surface the moment you lie down. It gives the mattress that plush hotel character without you sinking straight through to the springs.
Graphite memory foam
Graphite memory foam relieves pressure as you sleep while dispersing heat away from the body. If ordinary memory foam has left you overheating in the past, this layer is designed to prevent that.
Springs
Responsive springs combining mini comfort and traditional pocket springs for enhanced support. In practice that means the mattress adapts to your shape and weight rather than pushing back in one uniform way.
Cover
A breathable bamboo cover with a silky smooth knitted surface, naturally antibacterial and hypoallergenic. A sensible choice if you have allergies or simply sleep warm.

Key benefits
- Fits compact rooms: At 3ft x 6ft 3in, it leaves space for a desk or wardrobe beside it, and we suggest allowing at least 2.1m x 2.8m of floor space.
- Premium feel for one: You get all 2,740 springs' worth of the Severn's build scaled to a single sleeper, so a solo adult or teen sleeps on the same layered construction as the larger sizes.
- Cooler for warm teens: The graphite memory foam draws heat away from the body, which helps in a small bedroom where warmth tends to build up overnight.
- Twin beds for guests: Two UK singles side by side let a spare room host two friends separately, and the pillow top gives guests a soft first impression.
- Kinder to allergies: The bamboo cover is naturally hypoallergenic, a sensible choice for a child's room where dust tends to gather around toys and shelving.
This size suits you if...
You sleep alone and want a deep, plush mattress in a bedroom where every bit of floor counts, or you're furnishing a teenager's room with a mattress they can keep into adulthood. It also fits if you're setting up a guest room with two separate beds rather than one shared one.
Consider another size if...
You share the bed with a partner or like room to spread out. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for it.

FAQ's
Is the Sleepeezee Severn UK single too deep for a bunk bed or mid sleeper?
It may be. The Severn is 34cm deep, and raised frames such as bunks, cabin beds and mid sleepers usually set a maximum mattress depth so the safety rail stays effective. Check the frame maker's guidance before ordering. If the frame calls for a slimmer mattress, the Severn in a UK single is better placed on a standard divan or bedstead.
What size room do I need for a Sleepeezee Severn UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves enough room to walk around the bed and open a wardrobe or drawers, which matters in a child's bedroom where a desk and storage are often competing for the same wall.
Is a UK single Sleepeezee Severn big enough for an adult?
For one adult of average height, yes. It measures 90 x 190cm, so taller sleepers may find the length a little short: the UK king is 10cm longer. If you tend to sprawl, the UK double is 45cm wider and the same length, so it adds width without needing a longer room.
Should I get the Severn in a single or a double for a spare room?
Think about who stays. A single suits one guest or, paired with a second, two friends who won't share. For couples, the UK double gives 67.5cm each for two sharing, and we suggest at least 2.6m x 2.8m of floor space for it, compared with 2.1m x 2.8m for the UK single.
Is the Sleepeezee Severn worth buying in a single for a child?
It depends on their age. The Severn sits at the premium end, so for a young child who may outgrow a pillow top or move to a bunk, it's a lot to spend. For a teenager, yes, it makes more sense, as a UK single of this quality could follow them to a first flat.
