Layer Details
- 90cm of width each: Two people sharing get 90cm apiece, which means a partner who turns often through the night is unlikely to disturb you.
- Space for company: When a child pads in at 3am, or the dog treats the bed as routine, everyone still keeps a workable share of the mattress.
- Medium soft across a bigger surface: The gentler, cushioned feel of the Opulence has more room to work here, so side sleepers can spread out and still settle in.
- 30cm wider than the UK king: The UK super king is 30cm wider than the UK king and the same length, a difference you feel every night if you share.
- Suits a large master bedroom: In a big period room or generous new build master, a UK king can look undersized, while a super king fills the space properly.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, your children or pets regularly join you and a UK king has started to feel crowded, or your partner is genuinely restless and you've learned that distance does more for your sleep than any comfort layer could.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m minimum, or you sleep alone. We'd recommend the UK king instead, which is 30cm narrower and the same length, and needs a room of at least 2.7m x 2.9m.

What size is the Sealy Opulence super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That gives two people sharing 90cm of width each, the same as a UK single per person, and it's the largest size the Opulence comes in.
Is the Sealy Opulence super king good for couples with children?
It's the strongest choice in the range for that. With 180cm of width, a child wandering in at night still leaves everyone a reasonable share, and the medium soft feel is forgiving when three bodies settle at once. A UK king can manage the occasional visit, but a super king makes it comfortable rather than tolerated.
How much bigger is a super king than a king in the Sealy Opulence?
The UK super king is 30cm wider than the UK king; both are 200cm long. That extra 30cm is entirely about sharing space, so if you sleep alone the UK king may serve you just as well in this mattress.
What room size do I need for the Sealy Opulence super king?
We suggest at least 3m x 2.9m as a minimum, and a little more feels better in practice once you allow for wardrobes and walking space. Measure your door swing and landing turns too, because a mattress this wide is where tight corners start to bite.
Will a super king mattress get up my stairs?
At 180cm wide it's the size most likely to struggle with narrow staircases and tight landing turns, so measure both before ordering. Sealy publishes limited specification detail for the Opulence, so confirm with the retailer how it's delivered and whether it arrives rolled or flat.
