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.
Layer details from mattressonline.co.uk product page, September 2026.
- 75cm of space each: Two sharing get 75cm of width apiece, which means guests or tenants can settle into their own side rather than negotiating a smaller bed.
- Foam limits partner disturbance: There are no springs to transmit movement, so when one sleeper gets up early the other feels less of it, useful for couples on different schedules.
- 200cm of length: The UK king is 10cm longer than the UK double, so a guest over six foot won't find their feet hanging off the end.
- A double room that lets properly: If you advertise a rental as a couples' room, a UK king backs that up, and the Crib 5 certification means it's legally suitable for commercial premises.
- Light enough to move between rooms: At 10cm deep this is a slim, manageable mattress, so rotating it or shifting it upstairs in a rental is a one-person job.
This size suits you if...
You're furnishing a rental, guest house or student let and want the double rooms to sleep couples comfortably, with 75cm of width each and enough length for taller guests. It also fits if your visiting family stay for weeks at a time, perhaps with a new baby and a lot of pillow rearranging, and you'd rather they had space to spread out.
Consider another size if...
The room measures less than the 2.7m x 2.9m we suggest for a UK king, or the bed will mostly sleep one person. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m.

Is the Contract Pro UK king big enough for two adults?
Yes, comfortably. At 150 x 200cm it gives two sharers 75cm of width each, which is 7.5cm more per person than the UK double offers. The medium to firm foam also keeps movement on one side from travelling across, so it suits couples, or paying guests, who go to bed at different times.
What room size do I need for the Contract Pro in a UK king?
We suggest allowing at least 2.7m x 2.9m so there's walking space around the bed. Measure carefully in newer builds, where a master bedroom can feel generous empty but tight once wardrobes go in. If the room falls short, the UK double needs at least 2.6m x 2.8m and this mattress comes in that size too.
Is the Contract Pro king long enough for tall sleepers?
At 200cm, the UK king is 10cm longer than the UK single and UK double versions of this mattress. For a tenant or guest over six foot, that extra length is often the difference that matters more than width, so the UK king is the size we'd point you towards.
Is the king size Contract Pro heavy to move around a rental?
It's one of the easier king mattresses to handle. The slim 10cm foam construction keeps the weight down compared with a sprung king, and it arrives vacuum packed and rolled, so getting it up a narrow staircase in a terraced let or HMO is far less of a struggle.
