Ticking
The outer cover is made from soft to the touch, finest quality ticking. It's the surface you'll feel through your sheets, so the quality matters more than you might think.
Hand tufting and side-stitching
Hand tufting with felt washers holds the fillings in place, which means they won't shift or bunch over time. Three rows of hand side-stitching firm up the edges, so you get support right across the sleeping surface.
Springs and pockets
The 5 foot size contains 1720 vanadium steel springs, each with 6 coils, hand-nested in calico pockets beneath a wool protector pad. Individual pockets mean each spring moves independently, so you feel less disturbance from a partner turning over.
Fillings
The fillings are all natural: British fleece wool, horsehair, bamboo and cotton. Wool and horsehair are excellent at wicking moisture and regulating temperature, which means a cooler, drier sleep than synthetic foams tend to give.
Borders
The borders are upholstered in wool and include air vents and handles. Vents let the mattress breathe, and the handles make rotating it far less of a struggle.

Key benefits
- 90cm each for two: Each sleeper gets 90cm of width, which is 15cm more each than the UK king, so a partner who fidgets all night is far easier to sleep through.
- Distance plus independent springs: Individually pocketed springs limit movement travel, and the extra width of the UK super king adds physical distance on top, which helps light sleepers most.
- Space for small visitors: When a child climbs in at 3am, a 6ft x 6ft 6in surface usually leaves room for everyone rather than pushing one adult to the edge.
- Usable edges across a wide bed: Three rows of hand side-stitching keep the borders supportive, so the outer strips of this wide surface stay usable when a dog or child takes the middle.
- Same length as the UK king: The UK super king and the UK king are both 200cm long, so taller sleepers lose nothing by choosing the wider size.
This size suits you if...
You share the bed with someone who turns, kicks or gets up in the night and you want real distance between you, or children and pets regularly end up in your bed, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or you sleep alone most nights. We'd recommend the UK king instead, which is 30cm narrower and suits rooms of at least 2.7m x 2.9m.

FAQ's
Is the Vispring Imperial UK super king good if my partner is a restless sleeper?
It is one of the better set-ups for it. The UK super king gives 90cm each, 15cm more each than the UK king, and the springs sit in separate calico pockets so they move independently. The Medium tension suits most sleepers, although if you prefer a very soft surface Vispring also makes a soft version.
Vispring Imperial UK super king or UK king: which should I choose?
The UK super king is 30cm wider and the same length. Choose it if you share with a restless partner, children or a dog and your room allows at least 3m x 2.9m. If space is tighter, or two adults sleep quietly, the UK king needs at least 2.7m x 2.9m.
Can two adults, a child and a dog share a Vispring Imperial super king?
Occasionally, yes, and far more comfortably than on a smaller size. At 180cm wide there is space for a child between two adults. The hand side-stitched edges stay supportive, so whoever ends up near the border still has a usable sleeping surface rather than a soft, sloping edge.
Will a UK super king Vispring Imperial fit in a loft conversion bedroom?
Only if the room has enough full-height floor. The mattress measures 180 x 200cm (6ft x 6ft 6in), and we suggest at least 3m x 2.9m. In a loft conversion the slope usually decides which wall the headboard goes against, so measure the headroom at the sides where you'll get in and out.
