Key benefits
- Leaves floor space for everything else: At 90cm wide, the UK single leaves room beside the bed for a desk or wardrobe, which matters in a child's bedroom where toys and storage all compete for the floor.
- Steadier support where the hips sit: The firmer zone through the centre gives more support under the heaviest part of the body, which means a solo sleeper is less likely to dip in the middle.
- Flexible guest rooms: Two UK singles side by side let a spare room take friends, siblings or a couple, so guests who don't share a bed at home aren't forced to here.
- Helps in rooms that run warm: Comfort Breathe fibres help regulate temperature, which helps if the bed sits in a small loft conversion or box room that can get stuffy in summer.
- A gentle cover for a child's bed: Silentnight describes the aloe vera-infused cover as naturally hypoallergenic and antibacterial, a reassuring detail if you're buying for a youngster with sensitive skin.
This size suits you if...
You sleep alone and want a balanced medium feel, you're furnishing a child's or teenager's room where the floor has to fit a desk and wardrobe too, or you're setting up a spare room with two beds so guests can sleep separately.
Consider another size if...
You regularly share the bed, or you're an adult who likes room to spread out. The UK small double would suit you better: it is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m.

FAQ's
Will the Silentnight Castleton 800 Pocket Eco UK single fit a bunk bed?
The 90 x 190cm footprint matches standard UK single frames, including bunks, cabin beds and mid sleepers. Depth is the open question: Silentnight doesn't publish one for this mattress, and raised frames usually set a maximum mattress depth. Find your frame's limit first, then confirm the mattress depth with the retailer before you order.
What size room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m. That gives you space to walk round the bed and open a wardrobe, and in many children's rooms it still leaves a wall free for a desk or shelving. Siblings sharing a room will need a good deal more, as two beds plus a walkway adds up quickly.
Is a UK single long enough for a tall teenager?
At 190cm, the UK single is the same length as the UK small double and the UK double, so sizing up to either adds width but no extra length. Only the UK king and UK super king are 10cm longer. If your teenager already hangs off the end, width alone won't fix it.
Is the single Castleton 800 Pocket Eco a good choice for a guest room?
For most guests, yes. The medium rating suits the majority of back and side sleepers, so you're unlikely to pick a feel that suits nobody. Anyone who strongly prefers a firm or very soft bed may find it a little middle of the road, but for occasional stays that balance is sensible.
What bedding fits a UK single Silentnight Aloe Vera mattress?
Standard single sheets and a single duvet at 135 x 200cm will fit, and they're easy to find in any bedding shop. As Silentnight doesn't publish a depth, measure the mattress once it arrives before buying deep fitted sheets, so the corners stay put rather than pinging off overnight.
