Vispring Imperial Pocket Sprung King Size Mattress

Ticking
The outer cover is a soft to the touch, finest quality ticking. This is the surface you'll actually feel through your sheet, and it's made to be gentle against skin.
Fillings
All-natural fillings of British fleece wool, horsehair, bamboo and cotton, which means the mattress breathes and manages moisture naturally through the night. Horsehair in particular adds resilience, so the comfort layers spring back rather than compacting quickly.
Springs
1720 vanadium steel springs in the 5-foot size, each with 6 coils, hand-nested in calico pockets with a wool protector pad. Because each spring works independently, support follows your shape closely and movement on one side is less likely to disturb the other.
Borders
Wool-upholstered borders include air vents and handles. The vents let air circulate through the mattress, and the handles make rotating it far easier than wrestling an unhandled one.

Key benefits
- More width each than a UK double: You each get 7.5cm more than a UK double gives, a small figure on paper that you notice when one of you rolls over in the night.
- 1720 springs across this size: The UK king is the 5-foot size, with 1720 individually pocketed springs, so each of you is supported separately and a partner's movement travels less across the bed.
- Length for taller sleepers: At 200cm (6ft 6in), the UK king lets someone over six foot lie flat without their heels hanging off the end, which a UK double's shorter length can't always manage.
- Quieter mornings on different schedules: If one of you gets up hours before the other, the extra width and independent springs mean climbing out is less likely to wake the partner still asleep.
- Space without the super king's footprint: You get proper room for two while needing a smaller bedroom than the UK super king, where we suggest at least 3m x 2.9m.
This size suits you if...
You share the bed every night and have started to feel cramped on a UK double, one of you is close to six foot or taller, or your working hours differ and you'd like to get up without waking the other person.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 2.7m x 2.9m. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
Is the Vispring Imperial UK king long enough if you're over six foot?
Yes, for most tall sleepers. The UK king is 200cm long (6ft 6in), which is 10cm longer than a UK double. If one of you is over six foot, that extra length is often the bigger improvement, because it lets you stretch out fully rather than sleeping slightly curled up.
Will I feel my partner moving on a Vispring Imperial king size?
Less than on a smaller bed. You each get 75cm of width, and the 1720 springs in this size sit in separate calico pockets, so movement on one side stays mostly local. A restless partner may still register a little, but the UK king gives the springs more room to keep you apart than a UK double does.
Vispring Imperial UK king or UK super king for a couple?
The UK king gives you 75cm each, while the UK super king gives 90cm each, so 15cm more per person. Both are the same length. Choose the UK super king if you both sprawl or share with a dog, but check your room first: we suggest at least 3m x 2.9m, against 2.7m x 2.9m for the UK king.
Is it worth upgrading from a double to a Vispring Imperial king?
If you share every night, usually yes. The UK king is 15cm wider and 10cm longer than a UK double, giving you 7.5cm more width each. On a mattress designed to last decades, those nightly centimetres add up, although a solo sleeper would get less from the extra width.
Will a Vispring Imperial king fit in a new build master bedroom?
Measure after the wardrobes and bedside tables are in, because new build rooms often feel smaller once furnished. We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m giving comfortable space to walk around it. If you fall short, the UK double needs at least 2.6m x 2.8m.
