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
- Room to sleep apart in the same bed: You each get 90cm, which means a partner who kicks, turns or gets up early is far less likely to wake you than on a UK double or UK king.
- Space for night-time visitors: If a small child wanders in after a bad dream, the UK super king leaves enough width that nobody ends up clinging to the edge until morning.
- Independent springs across a wide surface: The Dartington's hand-nested pocket springs move on their own, so across a UK super king a dog settling at your feet barely registers on your partner's side.
- In proportion with a large room: In a period bedroom with high ceilings or a generous master, a UK king can look a little lost, whereas the UK super king's 6ft x 6ft 6in footprint fills the space properly.
- Extra width without extra length: The UK super king is 30cm wider than the UK king but the same length, so taller sleepers get the same legroom plus noticeably more elbow room.
This size suits you if...
You share the bed with a restless sleeper and want the most distance a mainstream size allows, or a child or large dog joins you most nights and everyone still needs a proper share of the mattress. It also suits you if your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is below our suggested 3m x 2.9m, or you want space to walk around the bed. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Vispring Dartington super king big enough for two adults and a child?
For occasional night visits, yes. The UK super king gives two adults 90cm each, which leaves enough room for a small child to squeeze in without anyone being pushed to the edge. Because the Dartington's pocket springs respond independently, a wriggling child in the middle disturbs the sleepers either side less than it would on a single spring unit.
Should I get the Vispring Dartington in a UK super king or a UK king?
The UK super king is 30cm wider than the UK king and the same length, giving each of you 15cm more width. That extra space matters most with a restless partner or regular company from children or pets. The trade-off is room: we suggest at least 3m x 2.9m for the UK super king, against 2.7m x 2.9m for the UK king.
How much bigger is a Dartington super king than a UK double?
Considerably. The UK super king is 45cm wider and 10cm longer than the UK double. When two of you share, the UK double gives 67.5cm each, while the UK super king gives 22.5cm more each. If you're upgrading from a UK double, expect the bed to take up a much larger share of the floor.
What size bedroom do I need for a Vispring Dartington super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable. In a loft conversion, measure where the ceiling slopes, since that usually decides which wall the headboard can go against. Check door swing and bedside table space too, as these tend to cause problems at this size.
Does a UK super king Dartington help with a restless partner?
It's one of the most effective choices you can make. Physical distance does more than any comfort layer, and the UK super king gives you 90cm each. Pair that with the Dartington's independently moving pocket springs and a partner's tossing and turning is much less likely to travel across to your side.
