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.
Layer details from mattressnextday.co.uk product page, September 2026.
- Room to sink in separately: The soft, cradling feel is nicer when you're not sharing it shoulder to shoulder, and 75cm each for two people sharing gives that surface space.
- Less disturbance at width: The 1400 pocket springs compress independently, and the extra width of a UK king puts more distance between you, so a partner leaving early is easier to sleep through.
- Length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, welcome relief if your feet currently hang near the edge.
- A comfortable fit for most bedrooms: We suggest allowing at least 2.7m x 2.9m, which most UK master bedrooms manage without the squeeze a UK super king can bring.
- Certified for shared, allergy-prone households: The Allergy UK Seal of Approval matters more when two of you breathe next to this mattress all night.
This size suits you if...
You share the bed every night and want more space than a UK double gives, especially with a soft mattress you both sink into. Or one of you is tall and keeps running out of length. It also suits couples on different schedules who want the pocket springs and extra width to soften the disturbance of one person getting up hours before the other.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king. In that case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m and gives up 15cm of width.

Is a UK king big enough for a couple on the Sealy Soothe Hybrid?
Yes, for most couples. You get 75cm each for two people sharing, and because Sealy describes this mattress as soft, that extra width matters: you can each sink into the memory foam without rolling towards one another. Restless partners are also better served here, since the 1400 pocket springs move independently and the added distance helps too.
How much space do two people get on this mattress in a UK king?
The UK king measures 150 x 200cm, which works out at 75cm each for two people sharing. That's 15cm more width overall than the UK double, a difference you notice every night on a soft mattress like this one, where you settle into the surface rather than lying on top of it.
Is the UK king Sealy Soothe Hybrid long enough for tall sleepers?
At 200cm, the UK king is 10cm longer than the UK double, so anyone approaching six foot gets proper clearance for their feet. If length is your main reason for upgrading, the UK king delivers it without the wider footprint of the UK super king, which is 30cm wider but the same length.
What room size does a UK king need?
We suggest allowing at least 2.7m x 2.9m. That leaves walking space on both sides for bedside tables and getting in and out. In a new build master bedroom, measure with the wardrobes in place, as the usable floor shrinks quickly. If the room can't manage it, the UK double needs at least 2.6m x 2.8m.
Where can I buy the Sealy Soothe Hybrid in a UK king?
Compare the retailers listed on this page. The prices shown here are updated as retailers change them, so it's worth checking back rather than assuming the first price you saw still stands. Availability varies by size, so a deal on the UK double won't necessarily apply to the UK king.
