Key benefits
- A proper spring count for a first mattress: Children and teens often get basic open-coil beds, so 800 pocket springs at this size means real, body-shaped support through growing years.
- Fits where other sizes won't: At 90cm wide, this single leaves room for a desk, wardrobe and floor space in a compact or awkwardly shaped bedroom.
- Medium firm suits changing sleepers: A guest bed hosts all sorts, and medium firm is the safest middle ground for back and front sleepers of most weights.
- Two can fit where one double can't: In a guest room or shared children's room, two UK singles with a walkway between them often works where a single larger bed would dominate.
- Cheap, easy bedding: Single sheets and a standard 135 x 200cm single duvet are the most widely stocked bedding of any UK size.
This size suits you if...
You're buying for a child or teenager moving up from a first bed, you're kitting out a spare room or student flat where the frame is provided and the mattress isn't, or you sleep alone in a compact room where every centimetre of floor space matters. It also suits a study that doubles as guest space, since the 90cm width leaves the desk usable.
Consider another size if...
You're an adult who shares the bed, or you simply want more room to stretch out. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

FAQ's
Will the Silentnight Pocket Essentials 800 single fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames, so width and length are fine. The thing to check is depth: raised frames usually have a maximum mattress height marked on the guard rail, so measure against the frame's own guidance before buying.
Is a UK single big enough for an adult on the Pocket Essentials 800?
For one adult, yes. At 90cm wide and 190cm long it's the standard UK one-person size, and the medium firm tension with 800 pocket springs supports most back and front sleepers well. Taller adults or anyone who sprawls may prefer the UK king, which is 60cm wider and 10cm longer.
Is the Pocket Essentials 800 single a good choice for a child's room?
It's a strong fit. The 90cm width leaves floor space for toy storage, a wardrobe and a desk in a typical child's bedroom, and pocket springs give better support than the basic open-coil mattresses often sold for kids. Medium firm also suits a growing sleeper as their weight changes.
How much room do I need for this single mattress?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That allows for the 90 x 190cm mattress plus room to walk alongside and open drawers or doors. It's a comfortable fit in box rooms, loft conversions with a narrow footprint, and studies doubling as guest space.
Should I buy two singles or one double for a guest room?
Two UK singles give you flexibility: solo guests, couples, or two friends who'd rather not share. Each single is 90cm wide, and the medium firm feel of this mattress suits varied guests. A UK double is 45cm wider than one single, so measure whether your room takes two beds plus a walkway.
