Layer Details
- Ecofoam. A layer of 100% recycled foam, which means a smaller carbon footprint during manufacturing than standard foam. It's naturally resilient and durable, so comfort and support hold up for longer.

- A safe fit for bunks and mid sleepers: At 10cm deep, this UK single sits well below the guard rail line on most bunk and cabin frames, where a thicker mattress would be a safety risk.
- Fits the smallest rooms: At 90cm wide, it leaves floor space for a desk, wardrobe and toy storage in a child's room, or two beds plus a walkway where siblings share.
- Ready for student lets: Crib 5 and BS7177: 2008 Source 5 certification makes the UK single legally suitable for houses in multiple occupation and halls-style rooms, which most household mattresses aren't.
- Washable cover for high turnover: The removable, washable cover suits guest rooms and rentals where different people sleep on the same UK single week after week.
- Light to carry upstairs: It arrives vacuum packed and rolled, and the slim single format is genuinely easy to manoeuvre into lofts, box rooms and up narrow staircases.
- Recycled foam that holds up: The Ecofoam layer is 100% recycled, which means a lower manufacturing footprint without giving up the resilience a hard-working guest bed needs.
This size suits you if...
You're furnishing a rental, student let or guest room and need a compliant one-person mattress at each bed, you're fitting out a bunk or mid sleeper where a slim profile keeps the guard rail effective, or you want two matching beds in a spare room that doubles as an office. The medium to firm feel copes well with a rotating cast of sleepers.
Consider another size if...
You're buying for a couple, or for tenants who'll share the bed. We'd recommend the UK double instead, which is 45cm wider and gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m of floor space for it.

Is the Contract Pro UK single suitable for a bunk bed?
Yes, and it's one of the better uses for it. At 10cm deep, the UK single sits low enough for guard rails on bunks, cabin beds and mid sleepers to stay effective, which many standard-depth mattresses can't manage. Check your frame takes a 90 x 190cm mattress before ordering, as some children's frames use shorter sizes.
What room size do I need for the Contract Pro in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That's our own guidance rather than the manufacturer's, and it leaves enough room to walk around the bed and open drawers. In practice the 90cm width fits box rooms, loft conversions with a narrow footprint and children's rooms that also need to hold a desk and wardrobe.
Can I put two Contract Pro UK singles in a guest room?
Yes, and it's a flexible setup: two UK singles give you separate beds for friends or grandchildren, pushed apart or together as needed. Each is 90cm wide, so measure your room with a walkway between them in mind. The washable covers help when guests come and go, and both meet the fire regulations required for paying guests.
Is the UK single Contract Pro right for a student room?
It's a strong match. Most student frames take a standard 90 x 190cm UK single, and the Crib 5 certification means it's legally suitable for HMOs and student accommodation. The 10cm depth is slimmer than a home mattress, but the medium to firm Ecofoam holds its shape well across successive tenants, and the price sits at the budget end.
How much bigger is the UK double Contract Pro than the single?
The UK single is 45cm narrower than the UK double, and the two are the same length. The UK double gives 67.5cm of width each for two sharing, and we suggest allowing at least 2.6m x 2.8m of floor space for it. For one adult who wants more sprawling room, the UK double is the size to look at.
