Layer Details
- Fillings. High-density polyester layers sit at the top, which means a resilient comfort surface that resists dipping over time. It won't feel plush, but on a firm mattress that's rather the point.
- Springs. Beneath the fillings sit 1,400 individually pocketed springs in the king size, each responding independently to your body shape and weight. In practice that means targeted support and less motion carrying across the bed to a partner.
Layer details from furniturevillage.co.uk product page, September 2026.
- Room to lie apart: You each get 75cm of width, which is 7.5cm more per person than the UK double and enough to stop elbows meeting in the night.
- Quieter early starts: The 1,400 pocketed springs in the UK king respond on their own, which means a partner leaving at dawn is less likely to jolt you awake.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, a change you'll feel straight away if one of you is over six foot.
- Firm across the full width: Back and front sleepers get the same firm, even feel from edge to edge, so neither side of the bed ends up as the softer one.
- Space without a super king room: You gain proper sharing space while needing less floor than the UK super king, which asks for at least 3m x 2.9m.
This size suits you if...
You share with a partner who keeps different hours and you want fewer disturbances when they get up, or one of you is over six foot and keeps running out of mattress on a UK double. It also suits back and front sleepers who both like a firm surface.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once furniture is in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Is the Sleepeezee Ortho Legacy 1400 king size good for couples on different schedules?
It's a sensible choice. The 1,400 springs in the UK king are individually pocketed, which means movement on one side travels less to the other. Add 75cm each and an early riser has room to get out without rolling across you. It won't be completely motion-free, but it's a clear step up from a cramped UK double.
Is the Ortho Legacy 1400 UK king long enough if you're over 6ft?
At 200cm, which is 6ft 6in, the UK king gives a tall sleeper noticeably more room than a UK double, with 10cm of extra length. If height rather than width is your reason for upgrading, the UK king and UK super king share the same length, so you don't need the bigger size just to stretch out.
Sleepeezee Ortho Legacy 1400 UK king or super king for two people?
The UK super king gives 90cm each, so the UK king gives you 15cm less per person. For most couples, 75cm each is comfortable. Size up if you regularly share with a child or a dog, and only if your room clears our suggested 3m x 2.9m for the UK super king.
Can one person turn a UK king Ortho Legacy 1400 on their own?
It's hard work. The mattress is double-sided and 30cm deep, and at 150 x 200cm the UK king is a large, awkward thing to lift and flip. Plan on two people for each turn. Sleepeezee doesn't publish a weight for the king size, so check the brand's own guidance if handling is a concern.
Will a UK king Ortho Legacy 1400 fit a new build master bedroom?
Measure after the wardrobes go in, as fitted units take more floor than a bare plan suggests. We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable. If your room is tighter, you'll likely end up squeezing past the foot of the bed every morning.
