Layer Details
- Cover. A breathable Belgian damask fabric cover, which means air can move through the surface rather than getting trapped against you. That helps keep things a little cooler overnight.
- Comfort Fillings. Soft white fibre fillings made from 100% polyester. These give a simple, even comfort layer over the springs rather than a deep, plush feel.
- Support System. Pocket springs mounted in their own separate fabric pockets, so each spring works completely independently of the others. You feel this as support that follows your body's shape, relieving pressure where you need it.

- More room each: At 75cm per sleeper, you each get 7.5cm more than on a UK double, which means fewer elbows and knees when one of you sprawls.
- Length for taller sleepers: The UK king runs to 200cm, 10cm longer than a UK double, so a partner over six foot can stretch out rather than curling up to keep their feet on.
- Calmer mornings on different schedules: Independently pocketed springs, plus the extra width, mean an early riser climbing out is a little less likely to wake the partner who is still asleep.
- Space for pillows and repositioning: If you are pregnant or recovering from surgery, the wider surface leaves room for supporting pillows while the medium firm feel gives you something steady to move on.
- Measure before you commit: We suggest a bedroom of at least 2.7m x 2.9m for the UK king, so measure a new build master bedroom once the wardrobes are in.
This size suits you if...
You share the bed every night and keep drifting into each other on a UK double, one of you is over six foot and wants the extra 10cm of length, or you get up at different times and want a partner's movements to reach you less.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m minimum. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Is the Spring King Pocket Backcare 1500 UK king big enough for two people?
For most couples, yes. The UK king measures 150 x 200cm, giving 75cm each, which is 7.5cm more per person than the UK double. If you are both broad-shouldered or a dog joins you most nights, it can still feel a little snug, although the pocket springs help keep one person's movement on their own side.
Spring King Pocket Backcare 1500 UK king size in feet?
The UK king is 5ft x 6ft 6in, or 150 x 200cm. The mattress is 25cm deep, so check your fitted sheets have deep enough pockets. If you are keeping an existing 5ft bed frame, measure inside the frame before ordering so the mattress sits snugly.
Is the UK king Spring King Pocket Backcare 1500 long enough for tall people?
It is 200cm long, which is 10cm longer than both the UK double and the UK single versions of this mattress. That extra length makes a real difference for anyone approaching six foot. Someone considerably taller may still find their feet close to the end, as this model does not come in a longer size.
Will I feel my partner move on a king size pocket spring mattress?
Less than you would on a traditional open coil. The springs here sit in separate fabric pockets, so pressure on one side does not drag the other down, and the UK king adds 15cm of width over the UK double to keep you further apart. Light sleepers with a restless partner may still notice some movement.
Should I get the Spring King Backcare 1500 in a double or king?
Choose the UK king if you share every night and your room is at least 2.7m x 2.9m, our suggested minimum. If space is tighter, the UK double needs at least 2.6m x 2.8m and gives 67.5cm each. Compare the retailers listed on this page, as the prices shown here update as retailers change them.
