Layer Details
- Fits compact rooms: At 90cm wide it slots into small bedrooms and loft conversions with narrow footprints, and we suggest allowing at least 2.1m x 2.8m of floor space.
- Firm support for growing sleepers: The Miracoil spring system gives sturdy, consistent support across the full 90cm width, which suits children and teens who need a stable surface rather than a soft one.
- A practical guest bed: Two UK singles fit where one larger bed dominates, so a spare room can sleep two visitors without giving up the whole floor.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding of any UK size.
- Usable edge to edge: The Miracoil system spreads support across the mattress width, which matters more at 90cm wide, where you tend to use every inch of the sleeping surface.
This size suits you if...
You're buying for a child's or teenager's room where the bed shares space with a wardrobe and desk, you need a supportive guest bed for a spare room that doubles as an office, or you're a solo adult in a compact room who prefers a firm feel. It also suits student rooms and first flats where a single frame is already provided.
Consider another size if...
You're an adult who shares the bed, or you find 90cm restrictive as a solo sleeper who spreads out. We'd recommend the UK small double instead: it's 30cm wider, the same length, and we suggest at least 2.4m x 2.8m of room for it.

Is the Silentnight Seoul Miracoil Memory available in a UK single?
Yes, the UK single is one of the sizes this mattress currently comes in, measuring 90 x 190cm. The lineup is limited, though: it's listed in UK single, small double and super king only, so there's no standard double or king. Compare the retailers listed on this page for live pricing on the single.
Is a UK single Seoul Miracoil good for a child's bedroom?
It's a strong fit. At 90cm wide it leaves floor space for toy storage, a wardrobe and a desk in a typical child's room, and the firm Miracoil support suits growing sleepers who need a stable surface. The memory foam layer softens the top slightly, so it doesn't feel harsh. Allow at least 2.1m x 2.8m of floor space.
Will this mattress work on a bunk or mid sleeper frame?
The UK single is the standard bunk and mid sleeper size, so the 90 x 190cm footprint should fit most frames. Raised beds often have a maximum mattress depth for safety rails, and Silentnight's published details don't confirm this for every frame, so check your frame's guidance before buying. The firm feel works well on slatted bunk bases.
How much smaller is the UK single than the small double?
The UK single is 30cm narrower than the UK small double, and the two are the same length at 190cm. That extra width buys a solo sleeper noticeably more room to move, but it needs a bigger bedroom: we suggest at least 2.4m x 2.8m for the UK small double, against 2.1m x 2.8m for the single.
Can two singles replace a double in a guest room?
Yes, and it's often the more flexible arrangement. Two UK singles let you host two guests who aren't a couple, and each bed is 90 x 190cm, so you'll need a walkway between them plus clearance around the room. The firm feel of this mattress suits occasional guest use, where a mattress gets slept on by all sorts of sleepers.
