Key benefits
- The standard couples' size for let rooms: At 135 x 190cm it sleeps two comfortably, which is what most rental listings and guest rooms need to advertise.
- 67.5cm of width per sleeper: Two people sharing get 67.5cm each, enough for visiting couples or tenants without demanding a larger room.
- Fits most UK bedrooms: We suggest a room of at least 2.6m x 2.8m, which covers the majority of second bedrooms, student lets and older terraced houses.
- Easy to move in: It arrives vacuum packed and rolled, and the slim 10cm profile makes the double far easier to carry up a turning staircase than a conventional mattress.
- Bedding is cheap and everywhere: Double sheets and 200 x 200cm duvets are stocked at every price point, which matters when you're dressing several rooms at once.
- Crib 5 certified in a shareable size: The double meets the fire regulations commercial premises require, so a couple's room in a rental is covered legally as well as practically.
This size suits you if...
You're furnishing a rental, guest house or student let and need rooms that can sleep two without demanding much floor space, or you're kitting out a whole property and want the size with the cheapest, most available bedding. It also suits a spare room where visiting couples stay occasionally, since 135 x 190cm shares well for short stays.
Consider another size if...
You're furnishing a room for a single tenant or a child, where the extra width is wasted. The UK single would suit better; allow at least 2.1m x 2.8m for it. For a premium let with a larger room, we'd suggest the UK king, with at least 2.7m x 2.9m.

FAQ's
Is the Contract Pro UK double big enough for two guests?
Yes, for the short stays it's designed around. Two people sharing get 67.5cm of width each, which works well for visiting couples or tenants. If you're setting up a premium room and have the space, the UK king gives 75cm each, so 7.5cm more per person, but the double is the practical default.
What size room do I need for the Contract Pro double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space and a wardrobe, and in most rooms bedside tables on both sides too. In a tighter single-occupancy room, the UK single needs only 2.1m x 2.8m and may make better use of the space.
Will the Contract Pro double get up narrow stairs in an older property?
More easily than most doubles. It arrives vacuum packed and rolled, and at 10cm deep it's slimmer and lighter to handle than a standard mattress, which helps on turning staircases in terraced houses and tight new build landings. Once unrolled it's a full 135 x 190cm, so plan the room before opening it.
What bedding fits the Contract Pro in a double?
Standard UK double bedding: double fitted sheets and a 200 x 200cm duvet. Because the mattress is only 10cm deep, ordinary fitted sheets will have plenty of spare depth, so there's no need for deep-fitted versions. Double bedding is the cheapest and most widely stocked size, useful if you're dressing several rooms.
Should I buy the Contract Pro in a double or a king for a rental?
The UK double suits most let rooms: it sleeps two and needs only 2.6m x 2.8m of floor space. The UK king is 15cm wider and 10cm longer, and needs at least 2.7m x 2.9m, so save it for larger rooms where you want to offer more space per guest.
