Key benefits
- More room each: At 75cm per sleeper, you each get 7.5cm more than on the UK double, which means turning over without nudging your partner awake.
- Length for taller sleepers: The UK king runs to 200cm, 10cm longer than the UK double, so a partner over six foot is far less likely to have their feet off the end.
- Quieter early starts: Each spring sits in its own pocket and moves independently, so an early riser climbing out disturbs less of the mattress under the person still asleep.
- A steadier edge: The reinforced mattress edge gives you a firmer place to sit while dressing or easing yourself in and out, a help during recovery from an injury or surgery.
- Kinder to smaller rooms: We suggest a room of at least 2.7m x 2.9m, which asks a little less of a new build master bedroom than the UK super king's 3m x 2.9m.
This size suits you if...
You share the bed and keep waking each other on a UK double, or one of you is tall enough that the foot of the bed has become the real problem. It also suits couples on different hours who want the early riser's exit to go unnoticed.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m once wardrobes and bedside tables are in. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

FAQ's
Is the Ikea Vatnestrom UK king long enough if you're over 6ft?
The UK king measures 200cm long, or 6ft 6in, which is 10cm longer than the UK double. For a partner over six foot, that extra length is often the bigger upgrade than the width, because it gives your feet room at the end of the mattress rather than resting on the edge.
How much space does each person get on a Vatnestrom UK king?
Two people sharing get 75cm each. On the UK double you'd each have 67.5cm, so the UK king gives you 7.5cm more apiece. That sounds small on paper, but it is the difference between lying shoulder to shoulder and having a little space to shift position at night.
Will a UK king Vatnestrom fit in a new build bedroom?
Allow at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m giving you comfortable room to move around it. New build master bedrooms can feel smaller once fitted wardrobes are in, so measure the free floor space rather than the room on the plans.
Should I get the Vatnestrom in a UK king or a UK super king?
The UK super king gives 90cm each, so the UK king gives you 15cm less per person. Both are the same length. The UK super king needs more room, and we suggest at least 3m x 2.9m for it. If your room is tight, the UK king is the more comfortable fit.
Will a Vatnestrom UK king stop my partner's early alarm waking me?
It should help, although no mattress removes movement entirely. The pocket springs respond individually, so your partner getting up moves less of the bed under you. On a UK king you also have 75cm each, so there is more distance between you and the side they climb out from.
