Upholstery
The comfort layers are made exclusively from natural fillings: bonded and blended British fleece wool with cotton, encased in high-quality ticking. It's hand-tufted with felt washers, which keeps the fillings anchored so the surface stays even over time.
Springs
Beneath the upholstery sits a single layer of 1,558 hand-nested vanadium steel pocket springs in calico pockets. Because each spring moves independently, you get support that follows your shape and less disturbance from a restless partner.

Key benefits
- More room each: At 75cm per person, the UK king gives each of you 7.5cm more than a UK double, which means fewer elbows and less edging towards the side of the mattress.
- Length for taller sleepers: The UK king is 10cm longer than a UK double, so anyone around six foot can stretch out without their feet hanging off the end.
- Quieter nights when schedules differ: Each hand-nested spring moves on its own, and the wider surface puts more distance between you, so an early riser is less likely to wake the other.
- Room to shift and prop: The extra width leaves space for a pregnancy pillow or a stack of cushions without pushing your partner towards the edge.
- A sensible middle ground: You get noticeably more space than a UK double while needing a smaller room than the UK super king, which we suggest for at least 3m x 2.9m.
This size suits you if...
You share the bed every night and wake each other more than you'd like, one of you is close to six foot and has run out of length on a double, or your bedroom comfortably clears our suggested minimum of 2.7m x 2.9m.
Consider another size if...
Your bedroom is tighter than our suggested 2.7m x 2.9m. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

FAQ's
Is the Vispring Dartington UK king big enough for two people?
For most couples, yes. The UK king gives 75cm each, which is 7.5cm more per person than the UK double. That is enough for many couples to sleep without touching. If one of you sprawls or you share with a dog, the UK super king's 90cm each may suit you better.
Is a Vispring Dartington king size long enough if you're over 6ft?
At 200cm, the UK king is 10cm longer than the UK double, and that extra length is often the reason taller couples upgrade. The UK super king is exactly the same length, so if length is your only concern, you gain nothing extra by sizing up.
Vispring Dartington UK king or UK super king: which should I choose?
The UK super king gives 90cm each, 15cm more per person than the UK king, but we suggest a room of at least 3m x 2.9m for it. For the UK king we suggest at least 2.7m x 2.9m. If your room sits between those two figures, the UK king is the safer fit.
Will I feel my partner move on a Dartington king size?
Less than on many mattresses. The springs sit in individual calico pockets, so movement stays fairly local. The 75cm each on the UK king adds some distance too. If one of you gets up hours before the other, that combination should help, although a very restless partner may still be felt a little.
Is it worth upgrading from a double to a Vispring Dartington king?
If you are cramped, usually yes. The UK king is 15cm wider and 10cm longer than the UK double. That is a modest step on paper, but you notice it every night. It does need more floor space, so check your room against our suggested 2.7m x 2.9m first.
