Layer Details
Comfort layer
Eco Comfort Fibre fillings sit on top of the springs. This is a simple fibre layer rather than foam, so expect a firm, fairly traditional surface rather than a deep, hugging one.
Spring system
A Miracoil open coil system with no roll-together and reinforced edges for more sleeping area. It gives you a firm, supportive base, and the stronger edges mean you can use more of the bed's width.

Key benefits
- Fits the smallest rooms: At 90cm wide, it leaves space for a desk, wardrobe and toy storage in a child's bedroom, or fits under the slope in a loft conversion.
- Firm support for growing sleepers: The Miracoil system gives a firm, stable feel, which means children and teens get consistent support rather than sinking into a soft surface.
- Sensible for guest and spare rooms: In a spare room that doubles as an office, a UK single takes up little floor space while still giving occasional guests a supportive night.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
- Works with student and rental frames: Most provided frames in student rooms and first flats take a UK single, so this mattress slots straight in without replacing the bed.
This size suits you if...
You're buying for a child or teenager and want a firm, supportive base rather than something soft, you need a guest bed for a spare room or study that does double duty, or you're kitting out a student room or first flat where the frame is already there and only the mattress is missing.
Consider another size if...
You're an adult sleeping in it every night and find 90cm restrictive when you turn over. The Silentnight Special Sleep also comes in a UK small double, which is 30cm wider and the same length; allow at least 2.4m x 2.8m for that size.

FAQ's
Is the Silentnight Special Sleep in a UK single good for a child's room?
Yes, with a caveat. Silentnight describes this mattress as supportive and firm, which suits children and teens who sleep on their back or front. The 90 x 190cm footprint is the UK standard for kids' beds, so it fits typical children's frames and leaves room for storage and a desk in a smaller bedroom.
Will the UK single Silentnight Special Sleep fit a bunk or mid-sleeper?
The width and length match standard bunk and mid-sleeper frames, which take a UK single as a matter of course. Raised frames often have a maximum mattress depth marked on the guard rail, and Silentnight doesn't publish detailed construction specs for this mattress, so check the depth against your frame's limit before buying.
What room size do I need for a UK single Silentnight Special Sleep?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open drawers or a wardrobe. Because the mattress is only 90cm wide, it also works where two beds share one room, such as siblings sharing or a guest room set up with twin singles.
Is a single big enough for an adult guest?
For occasional stays, yes. A UK single is the standard one-person size, and the firm Miracoil support holds up well for back and front sleepers. An adult using it every night may want more width to spread out, but for a spare room that spends most of its week as an office, it's a practical compromise.
