Ticking
The outer cover is made from soft to the touch, finest quality ticking. It is the surface you'll actually feel through your sheet, so the softness matters more than it might seem.
Hand tufting and side-stitching
The mattress is hand tufted with felt washers, which holds the fillings in place so they settle evenly rather than shifting into lumps. Two rows of hand side-stitching strengthen the border, giving you firmer support right to the edge.
Natural fillings
The fillings are all natural: British fleece wool, bamboo and cotton. Wool in particular regulates temperature well, drawing moisture away so you stay drier through the night.
Pocket springs
Each spring has 6 coils and is hand-nested in its own calico pocket. That means the springs respond to your body individually, so you get support where you press down without disturbing your partner.
Wool protector pad
The 5-foot size contains 1,326 vanadium steel springs, topped with a wool protector pad. The pad cushions the transition between springs and fillings, so you feel support rather than individual coils.
Wool-upholstered borders
The borders are upholstered in wool and include air vents and handles. The vents let the mattress breathe, while the handles make turning it a slightly less awkward job.

Key benefits
- More room each than a double: Each sleeper gets 7.5cm more than on a UK double, which sounds modest on paper but means knees and elbows stop colliding in the middle of the night.
- Quieter mornings on different schedules: The 1,326 springs in the UK king each sit in their own calico pocket, so when one of you gets up hours earlier, the other should feel far less of it.
- Length for a partner near six foot: At 6ft 6in long, the UK king is 10cm longer than a UK double, so a tall sleeper can stretch out with their feet on the mattress.
- Supportive edges where you each sleep: Two rows of hand side-stitching firm up the border, useful on a shared bed where each of you tends to settle towards your own side.
- Space without super king room demands: We suggest at least 2.7m x 2.9m for the UK king, a smaller footprint than the 3m x 2.9m we suggest for the UK super king.
This size suits you if...
You share the bed and keep waking when your partner shifts or leaves early for work, one of you is close to six foot and has run out of length on a double, and your bedroom comfortably clears 2.7m x 2.9m.
Consider another size if...
Your bedroom falls short of 2.7m x 2.9m once wardrobes and bedside tables are in. We'd recommend the UK double instead; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
How many springs are in the Vispring Realm UK king?
The 5-foot UK king contains 1,326 vanadium steel springs. Each one is hand-nested in its own calico pocket, which means the springs respond to your body individually rather than moving as a single sheet, and a wool protector pad sits on top so you feel support rather than coils.
Is the Vispring Realm king size long enough for someone over six foot?
The UK king measures 200cm, or 6ft 6in, which is 10cm longer than a UK double. For a partner approaching or just over six foot, that extra length is often the bigger improvement, giving room to lie straight without feet reaching the end of the mattress.
Will I feel my partner moving on a Vispring Realm UK king?
You should feel a lot less than on a smaller bed. The UK king gives you 75cm each, and the pocket springs move independently, so a partner turning over or getting up early disturbs your side far less. Very light sleepers may still notice someone climbing in or out.
Vispring Realm UK king or UK super king for a couple?
The UK super king gives 90cm each, so the UK king gives 15cm less each. Both are 200cm long. If you regularly share with a child or a dog, the UK super king may suit better, but we suggest at least 3m x 2.9m for it, against 2.7m x 2.9m for the UK king.
Is upgrading from a double to the Vispring Realm king worth it?
If space and disturbance are your main complaints, yes. The UK king is 15cm wider and 10cm longer than a UK double, giving 7.5cm more each. The catch is room: we suggest at least 2.7m x 2.9m, so measure after furniture is in, as a new build master bedroom can be tighter than it looks.
