Key benefits
- Sized for an ordinary bedroom: We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m giving you comfortable room to walk round both sides and make the bed.
- Space back for your furniture: The UK double is 15cm narrower and 10cm shorter than the UK king, which can decide whether a wardrobe door swings fully open or catches the bed frame.
- Simple to buy bedding for: Double sheets and a 200 x 200cm duvet are easy to find at any budget, which helps if you're kitting out a whole home in one go.
- Comfortable for visiting couples: In a spare room, the UK double lets two guests share for a few nights while leaving space for a chair or a suitcase on the floor.
- Generous for one sleeper: At 45cm wider than the UK single, a solo sleeper can spread out even with a dog or cat curled up in one corner.
This size suits you if...
You share the bed with a partner in a standard-sized UK bedroom and want to keep space for bedside tables and a wardrobe, or you sleep alone and like room to stretch out, perhaps with a pet settled at your feet.
Consider another size if...
You and your partner already feel short of space, or one of you tends to sprawl across the bed. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

FAQ's
Can I fit bedside tables either side of a UK double Rest Assured Cardigan?
In many rooms, yes. We suggest at least 2.6m x 2.8m for the UK double, although a room nearer 3m x 3m gives you a much easier fit for a small table on each side and space to get in and out without shuffling sideways.
How much room does each person get on the Rest Assured Cardigan Natural Pocket 1400 double?
The UK double gives you 67.5cm each when two of you share. Most couples find that fine, although it is 7.5cm less each than the UK king. If you tend to sleep close together, the UK double is usually enough.
Is the Rest Assured Cardigan UK double long enough if you're tall?
The UK double is 190cm long, or 6ft 3in. If either of you is close to that height, or your feet already hang over the end of the bed, the UK king is 10cm longer and would give you more room at the foot.
Is the Cardigan Natural Pocket 1400 in a UK double good for a guest room?
It suits a guest room well if you host couples. The UK double lets two adults share comfortably for a short stay, and because it takes up less floor than a UK king, a smaller spare room still has space for luggage.
How much wider is the Cardigan Natural Pocket 1400 double than the single?
The UK double is 45cm wider than the UK single, and both are the same length. That extra width makes the UK double workable for two people sharing, whereas the UK single is really a one-person bed.
