Layer Details
Knitted cover
A soft knitted cover with a wave pattern and embroidered label. It adds a touch of cosiness and warmth to the sleep surface.
Memory Foam
A plush layer of memory foam that cushions the hardest parts of your body, like the shoulders and hips. This is where the pressure relief comes from.
Pocket Springs
2000 pocket springs, each responding to your weight individually. This contours to your body and relieves pressure across the night.

Key benefits
- Space to share properly: At 75cm each, the UK king gives every sleeper 7.5cm more than a UK double, enough to stop elbows meeting when one of you rolls over.
- Less disturbance on early starts: If one of you is up hours before the other, the 2000 pocket springs respond individually, so the sleeper left behind feels far less of that exit across a wider surface.
- Extra length for taller sleepers: At 200cm long, which is 6ft 6in, feet are less likely to hang over the end than on any of the 190cm sizes.
- Room to prop and reposition: During pregnancy and the months after, the extra width leaves space for a wedge or bank of pillows without pushing your partner towards the edge.
- Fits more bedrooms than a super king: We suggest at least 2.7m x 2.9m for the UK king, a more modest ask than the 3m x 2.9m we suggest for the UK super king.
This size suits you if...
you share the bed every night and wake when your partner shifts or gets up early, one of you is tall enough to find a 190cm mattress a little short, or you are pregnant and need space to rearrange pillows without crowding the person beside you.
Consider another size if...
your bedroom falls short of our suggested 2.7m x 2.9m, or you both sprawl and still feel cramped at 75cm each. For a tighter room we'd recommend the UK double instead; for more space each, the UK super king.

FAQ's
Will I feel my partner move on the Memory Zone 2000 UK king?
Less than on a smaller shared size. The 2000 pocket springs each respond to the weight above them, so movement on one side travels less to the other. The UK king adds 75cm of width per person, which puts a little more distance between you as well. It won't make a restless partner invisible, but it should soften early-morning exits.
Is the Memory Zone 2000 UK king long enough for someone tall?
It is 200cm long, 10cm longer than the UK double, the UK small double and the UK single. That extra length suits anyone approaching 6ft who finds their feet near the end of a 190cm mattress. The UK super king is the same length, so sizing up beyond the UK king gains you width but no extra length.
Memory Zone 2000 UK king or UK super king for a couple?
The UK super king gives 90cm each, which is 15cm more per person than the UK king. It needs more floor space, though: we suggest at least 3m x 2.9m for the UK super king against 2.7m x 2.9m for the UK king. If your room clears the larger figure and you both spread out, go bigger.
Will a UK king Memory Zone 2000 fit a new build master bedroom?
Often, but measure after the wardrobes are fitted rather than from the floor plan, as fitted furniture eats space quickly. Allow at least 2.7m x 2.9m for the UK king, and remember the bed frame adds to the 150 x 200cm mattress. If you come up short, the UK double needs at least 2.6m x 2.8m.
Is the Memory Zone 2000 in a UK king easy to rotate on your own?
It's not advised. Across verified owner reviews, this mattress is described as heavy, and the UK king is a broad 150 x 200cm surface to turn by yourself. Mattress Online doesn't publish a weight for this size, so plan on two people for rotating it, or check the brand's own guidance before buying.
