Layer Details
- Upholstery. Every filling is natural: British fleece wool, hand-teased horsetail blended with real Shetland wool, silk and mohair, plus blended Shetland wool and cotton, all encased in high-quality ticking. In practice that means a breathable, temperature-regulating surface that softens with body shape rather than trapping heat the way foam can.
- Springs. Two layers of hand-nested calico pocket springs made from vanadium steel, with 2,520 springs in the 150 x 200cm size. Nesting the springs by hand in calico pockets lets each one move independently, which you feel as support that follows your shape closely.
- Borders. The borders are upholstered with protective coir and wool and finished with four rows of hand side-stitching. This stiffens the edges, so the mattress holds its shape over time and supports you when you sit or sleep near the side.

- More personal space: At 75cm each for two sharing, the UK king gives you 7.5cm more per person than the UK double, so elbows and knees meet a little less often.
- Less disturbance from a restless partner: There are 2,520 springs in the UK king, each moving independently, which means a partner turning over at 5am is far less likely to rock your side.
- Length for taller sleepers: The UK king is 200cm long, 10cm longer than the UK double, so feet stay on the mattress instead of pressing against the footboard.
- Usable right to the edge: The hand side-stitched borders stay firm, so on a UK king both of you can sleep near your own edge and use the full width.
- Space without super king demands: The UK king fits a bedroom from our suggested minimum of 2.7m x 2.9m, while the UK super king needs at least 3m x 2.9m.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, particularly if one of you gets up hours before the other. It also suits you if one partner is tall enough that a 190cm mattress leaves their feet hanging off the end.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m once wardrobes and bedside tables are in. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

Will the Vispring Sublime Superb UK king stop me feeling my partner move?
It should reduce it noticeably. The UK king has 2,520 independently moving pocket springs across its 150 x 200cm surface, and 75cm of space each for two sharing. If one of you leaves early for work, the springs under the other person stay largely undisturbed. The soft tension lets you sink in a little, so you stay settled in your own spot.
Is the Vispring Sublime Superb UK king long enough for a tall partner?
The UK king is 200cm long, which is 5ft x 6ft 6in in imperial, and 10cm longer than the UK double. It is also the same length as the UK super king, so if height is your main concern, sizing up beyond the UK king gains you width but no extra length.
Vispring Sublime Superb UK king or super king for a couple?
The UK super king gives 90cm each for two sharing against 75cm each on the UK king, so it suits couples who want real separation. It needs more floor space, though: we suggest at least 3m x 2.9m, compared with 2.7m x 2.9m for the UK king. If your room sits between those two, the UK king is the sensible choice.
Is it worth upgrading from a double to the Vispring Sublime Superb in king size?
For most couples, yes. The UK king is 15cm wider and 10cm longer than the UK double, which gives each of you 7.5cm more width. Allow for a room of at least 2.7m x 2.9m, with 3.2m x 3.2m more comfortable, and budget for king sheets and a 230 x 220cm king duvet.
Does a soft Vispring Sublime Superb UK king suit pregnancy?
A UK king leaves room for a pregnancy pillow or extra pillows on one side without pushing your partner towards the edge, since you each have 75cm to work with. The soft tension cushions hips and shoulders when you lie on your side. Heavier sleepers may find the soft tension too yielding, so compare Vispring's firmer tensions too.
