HD foam comfort layers
Two HD foam layers sit on top and are described as breathable. That gives you a comfortable surface with less heat build-up.
1000 pocket spring system
Independent pocket springs that shape to the contours of your body. Each spring works on its own, so the mattress supports you where you need it.
Ecofoam base
A high-density foam foundation made from 100% recycled foam offcuts. It gives the springs a supportive base and uses recycled material.

Key benefits
- Leaves floor free in a small room: We suggest at least 2.1m x 2.8m for a UK single, which means a box room can still fit a desk or toy storage beside the bed.
- Medium feel for growing children: Komfi describes the feel as medium, which gives a child or teenager some give at the shoulders without the surface feeling unsupportive as they grow.
- Springs that respond to one body: The 1000 independent pocket springs react to where you press down, so a single sleeper who shifts position overnight is supported in the new spot.
- Two singles for a guest room: A pair of UK singles lets friends or siblings sleep separately, and each mattress moves on its own because nothing joins them.
- Bedding that is easy to find: Standard single sheets and a single duvet (135 x 200cm) fit, so replacing bedding for a child's room or spare bed is straightforward.
- Check the depth for raised frames: At 25cm deep it sits fairly high, so on a bunk, cabin or mid sleeper you should confirm it suits the frame's safety rail before ordering.
This size suits you if...
You're buying for a child or teenager whose bedroom also has to hold a desk and wardrobe, or you're furnishing a spare room or loft conversion where only a narrow bed will fit. It also suits you if you want two separate beds in a guest room rather than one shared one.
Consider another size if...
You share the bed, or you sprawl and find 90cm too narrow. The UK small double would suit you better: it is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Will a UK single Komfi Vitality Hybrid fit a bunk bed or mid sleeper?
The UK single is 90 x 190cm, the standard size for most bunk, cabin and mid sleeper frames. Depth is the thing to check. This mattress is 25cm deep, and raised frames usually state a maximum mattress depth so the safety rail stays high enough. Komfi doesn't publish bunk guidance, so check the frame maker's figure first.
What size bedroom do I need for a UK single mattress?
We suggest at least 2.1m x 2.8m for a UK single. That leaves room to get in and out of bed comfortably with a little furniture alongside. In a child's room, sketch the bed, desk and wardrobe on paper before buying, because doors and drawers that open outwards need space too.
Is the Komfi Vitality Hybrid UK single long enough for a tall teenager?
The UK single is 190cm long, or 6ft 3in, the same length as the UK small double and UK double. A tall teenager who already hangs over the end should go for the UK king, which is 10cm longer. If your teenager still has growing to do, decide on length before width.
Should I put one UK small double or two UK singles in a guest room?
Two UK singles suit a room that hosts friends, siblings or grandchildren who wouldn't share a bed. One UK small double gives a single guest more room to spread out. The UK single is 30cm narrower than the UK small double, and we suggest at least 2.4m x 2.8m for a UK small double, so measure before choosing either.
What sheets and duvet fit a UK single Komfi mattress?
Standard single sheets fit the 90 x 190cm surface, and a single duvet measures 135 x 200cm. With a 25cm depth, pick fitted sheets labelled deep or extra deep so the corners stay tucked under. Single bedding is widely stocked, so spares for a child's room are easy to find.
