Layer Details
- Microquilted cover. A micro-quilted cover gives the sleep surface a smooth, soft finish. It's the first thing you'll feel when you lie down.
- Castellated foam. This foam is cut into grid-like sections, which means each zone can move independently. In practice, that helps the mattress adapt to different parts of your body.
- TrueGel Technology. Komfi's specialised gel layer is designed for temperature regulation. If you're a hot sleeper, this is the layer doing the heavy lifting for you.
- Pocket springs. A layer of 1000 adaptive pocket springs conforms to your body's contours. Each spring works on its own, which means support where you need it rather than a uniform push-back.
- Ecofoam base. The base is made from recycled, re-engineered Ecofoam. It's a durable foundation with a lighter environmental footprint than virgin foam.

- A grown-up spec in a compact footprint: The TrueGel layer and pocket springs are usually pitched at adult beds, so a teenager or solo sleeper gets proper temperature regulation rather than a basic foam slab.
- Leaves room for everything else: At 3ft wide, this size keeps floor space free for a desk, wardrobe or toy storage in rooms where a bigger bed would dominate.
- Guest rooms and dual-purpose spaces: In a spare room that doubles as an office, a UK single gives occasional guests spring support without swallowing the workspace.
- Medium firm feel that suits growing sleepers: Komfi rates it medium, which means a balanced feel rather than a hard surface, sensible for children and teens whose preferences are still settling.
- Sensible for hot young sleepers: If your child or teen runs warm at night, the gel layer gives heat a route away from the body instead of letting it build up.
This size suits you if...
You're buying for a child or teenager's room where the bed shares space with a desk and storage, you sleep alone and your room suits a 90cm width, or you're furnishing a spare room or student flat where the frame is already a standard UK single. Allow at least 2.1m x 2.8m of floor space and it will fit without crowding.
Consider another size if...
You're an adult who shares the bed, even occasionally, or you simply want more width 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.

Will the Komfi GelMed Comfort UK single fit a bunk or mid sleeper frame?
The footprint is standard at 90 x 190cm, so it matches most UK bunk and mid-sleeper frames. The thing to check is depth: this is a 25cm mattress, which is taller than many raised frames are designed for. Measure against the guard rail height on your frame before buying, as safety guidance varies by frame.
What size room do I need for a UK single Komfi GelMed Comfort?
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 wardrobe doors. It's a comfortable fit in box rooms, loft conversions with a narrow usable strip, and children's rooms where the bed competes with a desk and storage.
Is the Komfi GelMed Comfort UK single a good choice for a child or teenager?
Yes, with one caveat. The medium firm feel and pocket springs suit growing sleepers, and the gel layer helps teens who run hot at night. The caveat is price: this is a more premium spec than a basic children's mattress, so it makes most sense as a bed that will last through the teenage years.
Is a UK single big enough for an adult on this mattress?
For a solo adult, yes. At 90cm wide and 190cm long it's the standard UK one-person size, and the 1000 pocket springs adapt to an adult's weight the same way they do in the larger sizes. Taller adults should note the 190cm length; the UK king version is 10cm longer if that matters to you.
How much wider is a small double than this UK single?
The UK small double is 30cm wider than the UK single, and the two are the same length. That extra width suits a solo adult who wants more room to spread out. For the UK small double we suggest allowing at least 2.4m x 2.8m of floor space, so check your room before sizing up.
