Layer Details
Memory foam layer
A temperature-sensitive memory foam set below the cover that softens in contact with body heat. It means a gentle, contouring feel that adapts as you warm it.
Pocket spring core
Small-diameter pocket springs, each housed in its own cloth sleeve and working independently. This means support that responds to your body, with less of the whole bed moving at once.

Key benefits
- Fits small rooms comfortably: We suggest allowing at least 2.1m x 2.8m, which leaves space for a wardrobe and desk in a child's bedroom.
- A middle-ground feel for growing bodies: It's rated medium, which means a child or teenager gets some contouring from the foam without sinking in deeply.
- Steadier edges in a narrow bed: Ecofoam around the perimeter springs limits edge sag, which matters on a 90cm wide mattress where you're never far from the side.
- Sitting space in a spare room: Those firmer edges help if the bed also serves as somewhere to sit in a spare room that doubles as a study.
- Easy to keep clean: The cover unzips for machine washing, which is handy after spills in a child's room or between guests.
- Single bedding fits: Standard single sheets and a single duvet of 135 x 200cm fit, so you won't need to buy specialist bedding.
This size suits you if...
You're furnishing a child's or teenager's room where the bed has to share space with storage and a desk, or you need a guest bed for one in a spare room that also works as an office. It also suits you if you sleep alone and want a medium feel with some gentle contouring.
Consider another size if...
You share the bed with a partner most nights. In that case we'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m of floor space for it.

FAQ's
Will the Komfi Serenity Memory Pocket 1000 UK single fit a bunk bed or mid sleeper?
It measures 90 x 190cm, the standard UK single footprint most raised frames are built around. The deciding figure is depth: at 20cm, check the frame maker's maximum mattress depth so the guard rail still sits high enough above the sleeping surface. If they don't publish one, ask them before buying.
What size bedroom do I need for a UK single Komfi Serenity mattress?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That allows room to walk around the bed and open a wardrobe, which is why a single suits box rooms, children's bedrooms and loft conversions with a sloping ceiling over one side.
Is a UK single long enough for a tall teenager?
A UK single is 190cm long, the same length as the UK double. If your teenager is already close to that, the UK king adds length: the UK single is 10cm shorter than the UK king. We suggest at least 2.7m x 2.9m for the UK king, so it needs a much bigger room.
What sheets and duvet fit the Komfi Serenity in a UK single?
Standard single fitted sheets and a single duvet measuring 135 x 200cm fit. Single bedding is widely stocked, so spares for a child's room or guest bed are easy to find. With a 20cm depth, an ordinary fitted sheet should usually grip well, but check the pocket depth on the packaging.
Can I use the UK single Komfi Serenity as a daybed in a spare room?
It can work well. The ecofoam around the perimeter springs limits edge sag, so sitting along the long side of a 90cm wide bed should feel steadier. A narrow single pushed against a wall also frees up floor space for a desk when the room is mainly an office.
