Layer Details
- Quilted Cover. The cover is stitched together with the fillings beneath it, creating a patterned comfort quilt layer. In practice, that means the soft surface feel is built in rather than sitting loose on top.
- Wool. Deep layers of plush wool cushion your body at every point of contact. Wool insulates well, keeping you warm and snug, while its breathable structure helps prevent overheating.
- Pocket Springs. Each spring sits in its own fabric pocket and moves independently, a little like piano keys. This targets pressure relief precisely, adjusting to your movements and how your weight is distributed.

- Room to spread out: Each of you gets 75cm of width, so curling onto your side no longer means edging into your partner's half of the bed.
- Fewer wake-ups from a partner: Independent pocket springs soak up movement near where it happens, which means an early riser can slip out without jolting the person still asleep.
- Extra length for tall sleepers: At 200cm long, the UK king adds 10cm over a UK double, so a partner well over six foot can stretch out with their feet on the mattress.
- Soft enough for side sleeping: Deep wool fillings let shoulders and hips sink in gently, and the wider surface gives you space to shift position without disturbing anyone.
- Space for pillows and props: During pregnancy or recovery, a body pillow or wedge fits beside you on the UK king without pushing your partner towards the edge.
This size suits you if...
You share the bed every night and have outgrown a UK double, or one of you is tall enough that length matters as much as width. It also suits couples on different schedules, where one of you gets up hours earlier and you'd both like a calmer night.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Will I feel my partner moving on the Spring King Wool Luxury Soft 3000 UK king?
Less than on a smaller bed. The pocket springs move independently, so a partner turning over sends little motion across the surface, and on the UK king you have 75cm each rather than 67.5cm on a UK double. That extra gap between you means fewer accidental nudges, although a soft mattress will always show a little more sink where someone lies.
Is a UK king mattress long enough for someone over six foot?
For most tall sleepers, yes. The UK king is 200cm long, 10cm longer than a UK double, and that is the same length as the UK super king. So if length is your main reason for upgrading, sizing up to the UK super king would not add anything more at the feet, only width.
Should I get the Spring King Wool Luxury Soft 3000 in a UK king or UK super king?
The UK super king gives 90cm each, 15cm more than the UK king, but we suggest at least 3m x 2.9m of floor for it, against 2.7m x 2.9m for the UK king. If your room comfortably takes the larger footprint and you still bump into each other, go bigger; otherwise the UK king is the sensible choice.
Is a king size soft mattress good for sharing during pregnancy?
It can help a lot. The wool layers cushion hips and shoulders for side sleeping, and 75cm each on the UK king leaves room for a pregnancy pillow without crowding your partner. Getting in and out of a soft mattress can take a little more effort, so if that becomes difficult later on, keep the bed height in mind too.
How much bigger is the UK king than the UK double Spring King Wool Luxury Soft 3000?
The UK king is 15cm wider and 10cm longer than the UK double. Shared between two, that works out as 7.5cm more each, which sounds modest but is the difference between touching all night and having your own space. Allow at least 2.7m x 2.9m for the UK king, compared with 2.6m x 2.8m for the UK double.
