Layer Details
- Memory Foam. Memory foam moulds to your body as it warms, which means pressure points like hips and shoulders get cushioned rather than pushed against. It's the layer that gives this mattress its soft, cradling character.
- Tencel® Fibres. Tencel is a soft, eco-friendly fibre with a silky-smooth feel. It's naturally breathable, helping the sleep surface stay fresher through the night than foam alone would.
- 1400 Pocket Springs. Each spring sits in its own fabric pocket and compresses independently, which means support adjusts to your shape rather than the whole bed dipping. It also helps limit disturbance when a partner turns over.

- 90cm each, every night: Two people sharing get 90cm of width apiece, which means you can both stretch out fully without ever meeting in the middle.
- Distance plus pocket springs: The 1400 pocket springs compress independently to limit motion transfer, and at this width there is simply more mattress between you and a fidgeting partner.
- Space for company: When a child or a large dog treats your bed as their own, the super king absorbs the extra body without anyone losing their patch.
- Soft without the squeeze: Sealy describes the feel as soft and cradling, and having room to spread out means you sink in where you lie rather than rolling towards each other.
- Fills a large master properly: In a period property or a big new build main bedroom, a smaller bed can look lost; the super king matches the scale of the room.
This size suits you if...
You share the bed every night and want space to be a non-issue, your partner turns over often and you feel every movement at smaller widths, or children and pets regularly join you and you'd rather everyone kept their own patch. You'll also need the room for it: allow at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable.
Consider another size if...
Your bedroom falls short of our suggested 3m x 2.9m minimum, or the bed would dominate the space. We'd recommend the UK king instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

Is the Sealy Soothe Hybrid super king good for restless partners?
It's one of the better cases for going this big. The 1400 pocket springs compress independently, so movement doesn't travel far across the surface, and with 90cm of width each there's real distance between you as well. On a soft mattress where you settle into the surface, that extra separation matters more, since you're less likely to feel a partner shifting nearby.
Should I choose the Sealy Soothe Hybrid in a UK king or super king?
The UK super king is 30cm wider than the UK king; both are the same 200cm length. If children or pets join you regularly, or one of you is a light sleeper, the extra width is the difference between coping and sleeping well. If your room is under 3m x 2.9m, take the UK king, which we suggest needs at least 2.7m x 2.9m.
What room size does the Sealy Soothe Hybrid super king need?
We suggest at least 3m x 2.9m, and around 3.5m x 3.2m feels right, leaving space for bedside tables on both sides and a clear walkway. Check door swing and any tight landing turns before ordering too, because a 180 x 200cm mattress is an awkward shape to manoeuvre upstairs, particularly at 32cm deep.
Is the super king big enough for a family sharing the bed?
Yes, this is the size we'd point families towards. At 180cm across, two adults keep 90cm each, so a child climbing in during the night takes up slack rather than forcing anyone to the edge. The soft, cradling surface suits lighter bodies well, and the pocket springs keep one person's wriggling from waking everyone else.
Is a super king soft mattress too much sink for two people?
Not with this construction. The memory foam gives each of you your own cradled spot, while the 1400 pocket springs underneath respond to your individual weights, so you don't both roll into a shared dip. Heavier sleepers who need a firmer surface may still find it too soft, but that's true of this mattress at any size.
