Layer Details
- Upholstery. Bonded and blended British fleece wool with cotton, encased in high-quality ticking, which means a breathable, temperature-regulating sleep surface with no synthetic foam. It is hand-tufted with felt washers, so the fillings stay anchored rather than migrating and lumping over time.
- Springs. A single layer of 1,558 hand-nested vanadium steel pocket springs in calico pockets, based on the king size. Each spring moves independently, which means the mattress contours to your shape and limits motion transfer between partners.
Layer details from vispring.com product page, September 2026.
- Room to stop colliding: At 75cm each for two sharing, you get 7.5cm more personal space than on the UK double, which means less drifting into each other's half by morning.
- Length for a taller partner: At 200cm, the UK king is 10cm longer than the UK double, so a tall partner is less likely to sleep with their feet pressed against the footboard.
- Springs counted on this size: Vispring quotes its 1,558 hand-nested pocket springs for the king size, and each one moves independently, which limits how far one partner's movement travels across the bed.
- Fits more bedrooms than the UK super king: We suggest at least 2.7m x 2.9m for a UK king, against 3m x 2.9m for the UK super king, which matters in a modest main bedroom.
- Breathable across the full width: The wool and cotton upholstery lets heat escape across all 150cm, which helps when two warm bodies share one duvet.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, one of you is tall enough that the extra length makes a real difference, or you keep different hours and want a little more distance between your alarm and your partner's sleep.
Consider another size if...
You both sprawl, and 75cm each still sounds tight. We'd recommend the UK super king instead, which gives 90cm each and needs a room of at least 3m x 2.9m.

Is a Vispring Dartington UK king big enough for two adults?
For most couples, yes. The UK king gives 75cm each for two sharing, which is 7.5cm more each than the UK double. If you both sleep spread out, or a child regularly joins you, the UK super king gives 15cm more each, at 90cm per person.
Is the Dartington UK king long enough for a tall partner?
The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. If height rather than width is the reason you're upgrading, that extra length is the main gain. The UK super king is the same length, so sizing up again only adds width.
Will I feel my partner getting up on a Dartington UK king?
Less than on a narrower bed. Vispring quotes 1,558 hand-nested pocket springs for the king size, and each moves on its own rather than as a linked unit. With 75cm each, you also have a little more distance between you, which helps if one of you rises hours before the other.
Dartington UK king or UK super king for a couple?
The UK king suits most couples and fits a smaller room: we suggest at least 2.7m x 2.9m. The UK super king adds 30cm of width, but we suggest at least 3m x 2.9m for it. If your room is tight once wardrobes are in, the UK king is the safer choice.
Is a king size Dartington good for pregnancy with extra pillows?
The extra 7.5cm each over a UK double gives a bump pillow or wedge somewhere to go without pushing your partner towards the edge. The gently cushioned medium tension gives a little at the hips and shoulders for side sleeping. If you need even more room for pillows, consider the UK super king.
