Layer Details
- British fleece wool. A layer of British fleece wool sits at the surface, which means added warmth and a soft, breathable feel against the sleeping surface. Wool also wicks moisture, helping the mattress stay fresh.
- Hand-teased horsetail and Devonshire wool. Hand-teased horsetail blended with Devonshire wool gives a soft yet supportive surface. Horsetail is a traditional upholstery fibre prized for resilience, so this layer keeps its shape over time rather than compressing flat.
- British fleece wool. A second layer of British fleece wool cushions the transition between the upholstery and the springs. It adds a little extra softness and insulation above the spring unit.
- Pocket springs. A two-layer, hand-nested calico pocket spring construction with 2,030 vanadium steel springs in the 150 x 200cm size. Hand-nesting lets the springs work independently, which means support that follows your shape and less motion transfer to a partner.
Layer details from vispring.com product page, September 2026.
- Room to settle apart: At 75cm each, you can lie on your back without shoulders touching, which suits the firm tension because it rewards sleepers who stay put in one position.
- Quieter early starts: The 2,030 hand-nested pocket springs in the UK king respond individually, which means one of you leaving at dawn should cause less movement on the other side.
- Length for taller partners: The UK king is 10cm longer than a UK double, so a partner over six foot can stretch out without heels resting on the edge.
- A step up that still fits: The UK king needs less floor space than the UK super king, which matters in a new build master bedroom once fitted wardrobes are in.
- Firm support across the full width: Yes, a firm mattress feels less forgiving, but on a UK king both of you get the same steady spring support from edge to centre.
This size suits you if...
You share the bed every night and a UK double now feels crowded, one of you gets up hours before the other and you want less disturbance, or one partner is over six foot and the extra length matters more to you than extra width.
Consider another size if...
You both sprawl and still feel crowded with 75cm each. The UK super king would suit you better, giving 90cm each; we suggest at least 3m x 2.9m for the UK super king.

How many springs are in the Vispring Kingsbridge UK king?
Vispring quotes 2,030 hand-nested vanadium steel pocket springs for the 150 x 200cm size, which is the UK king. The springs sit in two layers of calico pockets, so each one can respond to the weight above it without dragging its neighbours down.
Is the Vispring Kingsbridge UK king long enough for someone over 6ft?
At 200cm, the UK king is 10cm longer than a UK double, which gives a tall sleeper noticeably more room at the foot end. The UK super king is the same length, so if length is your only concern, sizing up to the UK super king adds width but no extra length.
Will I feel my partner move on a Kingsbridge UK king?
You should feel less than on a UK double. Each of you has 75cm of width, and the hand-nested springs work independently, so movement stays closer to the person making it. A partner with a very different schedule may still be noticed getting in or out, though usually far less than before.
Vispring Kingsbridge UK king or UK super king: which should couples choose?
The UK king gives 75cm each, 15cm less each than the UK super king's 90cm. If you both lie still and simply want more room than a UK double, the UK king will usually be enough. Choose the UK super king if you need that extra width and your room allows at least 3m x 2.9m.
Will a Vispring Kingsbridge UK king fit a new build master bedroom?
We suggest allowing at least 2.7m x 2.9m for the UK king, with 3.2m x 3.2m comfortable. Measure after wardrobes and radiators are accounted for, as new build rooms often lose more floor space than the plans suggest. Also leave room to walk around both sides of the bed.
