2000 Zoned Mirapocket spring system
- Real space for two: At 75cm each for two people sharing, you can both settle into the box top's cushioning without negotiating over the middle.
- Fewer wake-ups on different schedules: The 2,000-spring Mirapocket unit responds to each sleeper separately, which matters when one of you gets up hours before the other.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, so anyone approaching six foot stops sleeping diagonally.
- Softness that suits sharing: The medium soft, hand-tufted box top lets side sleepers sink in a little on their own side, with the springs keeping weight spread evenly.
- Room for the extras: A dog who claims the foot of the bed, or a stack of pillows in pregnancy, fits far more comfortably at 5ft x 6ft 6in.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially with a soft mattress you both sink into. One of you keeps different hours and the other feels every exit. Or one of you is approaching six foot and needs the 200cm length as much as the width.
Consider another size if...
Your bedroom falls below our suggested 2.7m x 2.9m minimum, or the bed is mostly slept in alone. We'd recommend the UK double instead; it's 15cm narrower and 10cm shorter, and we suggest at least 2.6m x 2.8m for it.

Is a UK king Mirapocket 2000 Deluxe Box Top good for couples?
Yes, and it's arguably the size this mattress makes most sense in. You get 75cm each for two people sharing, and the 2,000 pocket springs in this size absorb movement locally rather than sending it across the bed. The medium soft box top is forgiving for side sleepers, though heavier couples may find it a little too yielding.
How many springs does the UK king size have?
The Mirapocket support unit holds 2,000 springs in the UK king. Spring counts are usually quoted for this size, and the zoned layout spreads two sleepers' weight evenly, which is part of why one person turning over is less noticeable on the other side.
Will this mattress suit a tall sleeper in a king size?
The UK king is 200cm long, which is 10cm longer than the UK double, so sleepers approaching six foot get their feet on the mattress rather than at its edge. The plush box top means taller side sleepers can stretch out and still feel cushioned at the shoulder and hip.
What room size do I need for this king mattress?
We suggest at least 2.7m x 2.9m, with more feeling comfortable once wardrobes and bedside tables go in. New build master bedrooms can be tighter than they first appear, so measure with furniture in mind. If your room is smaller, the UK double needs at least 2.6m x 2.8m by our guidance.
Should I size up to the super king instead?
The UK super king is 30cm wider than the UK king, though the two are the same length, so it's a width upgrade only. If a pet routinely shares the bed or you both spread out, that width helps; we suggest at least 3m x 2.9m of room for it. Compare the retailers listed on each page before deciding.
