Layer Details
Comfort Layer
Soft white fibre fillings sit at the surface, which means a cosy, slightly cushioned feel over the firmer springs beneath. It is a simple comfort layer rather than a deep plush one.
Support System
800 individual pocket springs, each sitting inside its own fabric pocket, move independently. In practice that means support tailored to your shape and less motion transferred across the bed when a partner moves.
Cover
A damask cover, a finely woven and durable fabric that feels soft to the touch. Woollen tufts pass through the mattress to keep the fillings from shifting over time.

Key benefits
- More room each than a UK double: You each get 75cm, which is 7.5cm more per person than the UK double, enough to lie flat without brushing a partner's shoulder.
- Extra length for taller partners: At 200cm long, the UK king is 10cm longer than the UK double, so a partner over six foot is less likely to have feet hanging off the end.
- Fewer wake-ups on split schedules: The 800 springs each sit in their own pocket and move independently, so an early riser climbing out disturbs the other side less.
- Space to change position: The extra width helps if one of you props up on pillows or shifts about through the night, as many people do during pregnancy.
- Firm enough for easier getting up: The medium firm tension gives a steady surface to push against, although owners mention wanting more edge support, so sitting on the edge may feel less secure.
This size suits you if...
You share the bed with a partner and wake each other when one of you turns over or gets up early, or one of you is over six foot and the UK double feels short at the foot. It also suits you if you want more room each without committing floor space to a super king.
Consider another size if...
You routinely share the bed with a dog or need a lot of space to spread out. We'd recommend the UK super king instead, which gives 90cm each; allow at least 3m x 2.9m.

FAQ's
Will a UK king Sleepeezee Classic Ortho 800 fit in a new build master bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king. New build master bedrooms can feel smaller once fitted wardrobes are in, so measure the floor you actually have left, not the room's listed size, and allow space to open doors and drawers.
Is the Classic Ortho 800 UK king long enough for someone over six foot?
The UK king is 200cm long, which is 6ft 6in, and 10cm longer than the UK double. For a partner over six foot, that extra length is often the real reason to upgrade, because it gives room for a pillow at the top and feet at the bottom.
How much space do two people get on a UK king Classic Ortho 800?
Two people sharing get 75cm each, which is 7.5cm more each than the UK double. The UK super king gives 90cm each, so if you already feel cramped on a UK double and like to sprawl, the UK super king may suit you better.
Does a UK king Classic Ortho 800 reduce partner disturbance?
The extra width puts a little more distance between you, and the individually pocketed springs move independently, so motion from one side travels less to the other. That helps partners on different schedules, although no spring mattress removes movement entirely.
Is it worth going from a UK double to a UK king in the Classic Ortho 800?
If you wake each other or one of you is tall, the UK king adds 15cm of width and 10cm of length over the UK double. You will need a room of at least 2.7m x 2.9m, compared with 2.6m x 2.8m for the UK double. Compare the retailers listed on this page for current prices.
