Layer Details
Memory Foam Top Layer
A top layer of memory foam that moulds to your shape, which means the surface cradles your body rather than pushing back against it. Expect that slow, sinking-in feel memory foam is known for.
Octaspring Technology with Body Zones
Hundreds of Octasprings adapt three-dimensionally to ease pressure at the back, hips and shoulders, so support shifts as you move rather than staying rigid. Three Body Zones mean each area of your body gets a comfort point tuned to it.

Key benefits
- Fits where other beds won't: At 90cm wide it needs a room of just 2.1m x 2.8m by our guidance, leaving space for a wardrobe, desk and toy storage in a child's bedroom.
- A gentle feel for lighter bodies: The Medium/Soft memory foam surface responds to lighter sleepers, so a child or teen sinks in and gets cushioning rather than lying on top of an unyielding slab.
- Octasprings that adapt to one sleeper: The foam Octasprings adjust three-dimensionally beneath a single body, which means pressure relief at the shoulders and hips without a partner's movement to work around.
- Guest room friendly: In a spare room that doubles as an office, or one holding two beds, the 90cm width keeps a walkway clear on at least one side.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked and least expensive bedding of any UK size.
This size suits you if...
You're buying for a child's room or a teenager and need the bed to share floor space with a desk and storage, you're a solo adult in a compact bedroom or first flat where a wider mattress simply won't go, or you're kitting out a spare room and want a bed that leaves the room usable for other things.
Consider another size if...
You share the bed, or you're a solo adult who likes to spread out. We'd recommend the UK double instead: it's 45cm wider than the UK single, the same length, and we suggest a room of at least 2.6m x 2.8m for it.

FAQ's
Is the UK single Octasmart Premium Deluxe a good choice for a child's bedroom?
Yes, with one caveat. The 90 x 190cm footprint suits a child's room well, needing only 2.1m x 2.8m of floor space by our guidance, so there's room left for a desk and toy storage. The Medium/Soft feel works nicely for lighter bodies, although a child who prefers a firm, flat surface may find it a little soft.
Will this mattress fit a bunk bed or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames, so width and length are fine. Raised frames also limit mattress depth for guardrail safety, and Dormeo doesn't publish a depth figure in the details we have, so check the measurement against your frame's guidance before buying.
Should I buy the UK single or size up to the UK double?
For a child, teen or a compact room, the UK single is the practical pick. If you're an adult who wants room to spread out and the bedroom can take it, the UK double is 45cm wider, the same length, and we suggest allowing at least 2.6m x 2.8m of floor space for it.
Is the UK single long enough for a tall teenager?
At 190cm (6ft 3in) long, the UK single suits most teens and adults comfortably. If they're already approaching six feet with growing left to do, the UK king runs 10cm longer, though it's also 60cm wider and needs a room of at least 2.7m x 2.9m, which is a big jump for most bedrooms.
