Pillow top with easyflex Gel foam
A pillow top that encases a 3cm layer of breathable easyflex Gel memory foam, along with polyester fibre. It gives the surface a plush, cushioned feel and some contouring.
Dense polyester fibre layer
A 3cm layer of dense polyester fibres. It adds cushioned comfort, so the surface feels softer without losing the support beneath.
Mirapocket pocket springs

Key benefits
- More room each than a UK double: The UK king gives you 7.5cm more each than a UK double, which means a little more space to turn over without bumping your partner.
- Springs that move independently: Each of the 1000 Mirapocket springs sits in its own fabric pocket, so a restless partner on a 150cm-wide surface should travel less across to your side.
- Length for taller sleepers: At 200cm long, the UK king is 10cm longer than a UK double, which means a tall partner is less likely to have feet hanging over the end.
- Sides you can use: A reinforced rod edge border helps the sides hold their shape, so the full width is usable and sitting on the edge to get up feels steadier.
- Cushioned without feeling saggy: The pillow top and gel memory foam add a plush surface over the springs, giving both of you cushioning while the pocket springs beneath keep you supported.
This size suits you if...
You share the bed every night and keep waking when your partner turns over or gets up early, or one of you is tall and has always slept with feet near the end. It also suits couples who want a cushioned medium feel with more personal space than a UK double gives, in a bedroom of at least 2.7m x 2.9m.
Consider another size if...
Your bedroom is tight once wardrobes are in, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is a UK king big enough for two people who disturb each other at night?
For most couples, yes. A UK king gives you 75cm each, and the individually pocketed springs respond to the person lying on them rather than across the whole surface. If one of you leaves for work hours before the other, that combination should mean fewer early wake-ups. If you still want more space, the UK super king gives 90cm each.
How much bigger is a UK king than a UK double?
The UK king is 15cm wider and 10cm longer than a UK double. Shared between two, that's 7.5cm more each: a UK double gives 67.5cm each, a UK king 75cm. It sounds modest on paper, but it's the difference between brushing against a partner and having a clear gap between you.
What size bedroom do I need for a UK king mattress?
We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m giving comfortable room to walk round and fit bedside tables. New build master bedrooms can feel smaller than expected once wardrobes go in, so measure with furniture in place, not an empty room.
Is a king size mattress long enough for a tall person?
A UK king is 200cm long, or 6ft 6in, which is 10cm longer than a UK double. For a tall partner, that extra length is often a bigger improvement than the width. The UK super king is the same length, so sizing up beyond a UK king adds width only.
Will a UK king pillow top mattress fit through my doors and up the stairs?
This mattress isn't rolled and boxed, so the full 150cm width and 31cm depth have to get through your hallway and round any turns in the stairs. A pillow top can't be squashed much. Measure narrow landings and doorways first, then compare the retailers listed on this page for the UK king.
