Pillow top
A pillow top filled with Woolkeepers wool and polycotton. It sits above the firm core, so you get a softer first feel on the surface without losing the firm support underneath.
Pocket spring core
1,200 ReActive 7-turn pocket springs in the king size. Each spring works on its own, so you should feel less disturbance when a partner moves, and the core gives its firm, supportive feel.

- Room to sleep apart, together: At 75cm each for two people sharing, you can both settle into your own space, useful when one of you is up hours before the other.
- Less disturbance across the width: Pocket springs move independently, and the extra width of a UK king means a partner's movements start further away from you in the first place.
- Length for taller sleepers: At 200cm long, the UK king suits anyone approaching six foot who finds their feet at the edge of a standard-length bed.
- Firm support with a softer surface: The firm tension holds you level while the pillowtop softens first contact, which two sharers of different weights often find easier to agree on.
- A substantial bed for the space: The 31cm depth on a 150cm-wide frame makes a genuinely imposing bed, so measure up and allow at least 2.7m x 2.9m of floor space.
This size suits you if...
You share every night and a double has started to feel tight, especially if one of you keeps different hours and you'd rather not feel every early alarm. It also suits a couple where one partner is tall, since the 200cm length gives feet somewhere to go, or where a dog has quietly claimed a corner and you need the width back.
Consider another size if...
You sleep alone in a modest room, or you're a lightweight side sleeper who needs give at the shoulder, as the firm tension may feel unyielding. The UK king is currently the only size listed for this mattress.

Is the Hypnos Bespoke Opal Pillowtop available in sizes other than UK king?
Not at the moment. The UK king, at 150 x 200cm, is the only size currently listed for this model. If you need a double or super king, you'd be looking at a different Hypnos mattress. Compare the retailers listed on this page for the UK king, as the prices shown here are updated as retailers change them.
Is a UK king big enough for a couple on a firm mattress?
Yes, and arguably more so than on a softer bed. You get 75cm each for two people sharing, and because the firm tension keeps you on your own side rather than rolling towards a dip in the middle, that width stays usable. Add the independent pocket springs and a restless partner should bother you less.
What room size do you need for the Hypnos Bespoke Opal Pillowtop in a UK king?
We suggest at least 2.7m x 2.9m, with around 3.2m x 3.2m feeling comfortable. New build master bedrooms can be tighter than they first appear once wardrobes go in, so measure the clear floor space rather than the room itself. Remember the bed will sit tall too, given the 31cm mattress depth.
What bedding fits the UK king version of this mattress?
Standard UK king sheets fit the 150 x 200cm footprint, but the depth is the thing to check. At 31cm, this mattress needs deep or extra-deep fitted sheets, as regular ones will ping off the corners. A 230 x 220cm king duvet is the usual pairing.
Is the UK king long enough for someone over six foot?
At 200cm, or 6ft 6in, it gives most tall sleepers comfortable clearance, and it's 10cm longer than a UK double. If one of you has been sleeping diagonally or hanging feet off the end, the length is often the upgrade you'll notice most, rather than the width.
