Layer Details
- Cover. A Belgian Damask viscose sleep surface that feels silky and soft to the touch. It's highly breathable, which helps keep the sleeping environment fresher through the night.
- Comfort fillings. A blend of sustainably sourced British wool, cotton, cashmere and silk. These natural fibres breathe and wick moisture, which means you're less likely to overheat.
- Support system. 5,000 individually pocketed springs sit beneath the fillings. Each spring moves on its own, so the mattress contours to your body and responds where you need support.

- Room for two without crowding the room: At 135 x 190cm, the UK double fits where a UK king would leave little space to walk around it, and we suggest allowing at least 2.6m x 2.8m.
- Less disturbance at closer quarters: With 67.5cm each, you sleep nearer your partner than on a UK king, so its 5,000 pocketed springs, each moving on its own, help keep their restlessness on their side.
- Fresher when two of you share: Two people give off more heat than one, and the wool, cotton, cashmere and silk fillings wick moisture, which means less of a clammy feeling on a shared bed.
- Space for a bedside table each: In a typical main bedroom, the 135cm width often leaves room for a bedside table on each side, so neither of you has to reach across the other at night.
- A sensible guest room choice: For visiting couples, the firm, supportive feel suits most back and front sleepers, although lightweight side sleepers may find it a little unyielding at the shoulder and hip.
This size suits you if...
You share the bed with a partner and want a firm, sprung feel in a bedroom of at least 2.6m x 2.8m, or you're kitting out a guest room where visiting couples will stay and you'd still like space for bedside tables on both sides.
Consider another size if...
You and your partner are both tall or broad-shouldered and already find 67.5cm each a squeeze. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

How wide is the Ortho Tranquility 5000 UK double for two people?
The UK double is 135cm wide, which gives each of you 67.5cm when sharing. That suits most couples who sleep fairly still, and the independently pocketed springs help when one of you moves. If you'd like more space, the UK king gives 75cm each, so the UK double gives 7.5cm less per person.
What size bedroom do I need for a UK double Ortho Tranquility 5000?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m feeling comfortable once bedside tables and a wardrobe are in place. If your room is smaller than our suggested minimum, measure carefully before ordering, because a bed that blocks drawers or doors quickly becomes frustrating.
What are the Ortho Tranquility 5000 double dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm. That matches the standard UK double, so it should sit properly on a UK double bed frame or divan base without gaps at the edges.
Should I size up the Ortho Tranquility 5000 from a UK double to a UK king?
Size up if your room allows it and you want more personal space. The UK king is 15cm wider and 10cm longer than the UK double, and we suggest at least 2.7m x 2.9m for the UK king. If your bedroom is nearer 2.6m x 2.8m, the UK double keeps a comfortable walkway around the bed.
Is the double Ortho Tranquility 5000 long enough if you're tall?
The UK double is 190cm long, the same length as the UK single. If you're tall and your feet tend to reach the end, the UK king and UK super king are each 10cm longer than the UK double, which gives you more room to stretch out.
