- Fits almost any room: At 90cm wide it slots into loft conversions, box rooms and student flats where a wider mattress simply wouldn't leave a walkway.
- Gentle feel for lighter bodies: The medium soft surface gives at the shoulder and hip, which suits teens and lighter adults who tend to find firmer beds unyielding.
- Room to live around it: We suggest a minimum floor space of just 2.1m x 2.8m, leaving space for a desk or wardrobe alongside the bed.
- A comfortable guest option: In a spare room that doubles as an office, this size keeps the room usable by day while still giving guests a genuinely soft night.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, so dressing this mattress costs less than any larger sibling.
This size suits you if...
You sleep alone, you like a softer surface that lets you sink in a little, and your room is compact, perhaaps a loft conversion where the bed sits under the slope, or a spare room that has to earn its space as an office too. It also suits a teenager who has complained of pressure points on a firmer bed, provided the budget stretches to a premium mattress.
Consider another size if...
You share the bed, even occasionally, or you're an adult who finds a 90cm width restrictive when you spread out. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space.

Is the Sealy Opulence UK single a good choice for a child's room?
It fits well physically: at 90 x 190cm it leaves space for toy storage, a wardrobe and a desk in most children's rooms. The medium soft feel suits lighter bodies too. The one caveat is price. This is a premium mattress, and many parents will prefer to spend less on a bed a child may outgrow.
Will the Sealy Opulence single fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames. Depth is the thing to check: raised frames often have a maximum mattress height for the safety rail, and Sealy doesn't publish full specification detail for this model, so confirm the depth with the retailer before ordering.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That's our own guidance rather than Sealy's, and it gives you room to open a door, walk down one side of the bed and fit a small piece of furniture. In a loft conversion, also check headroom where the bed will sit under the slope.
How much smaller is the UK single than the UK double?
The UK single is 45cm narrower than the UK double, and the two are the same length. That 45cm matters if you're a solo adult who sprawls, but if the room is tight the UK single keeps a walkway clear where the UK double might not. For the UK double, allow at least 2.6m x 2.8m.
Is the Sealy Opulence in a single worth it for a guest room?
If guests are occasional, a cheaper single may make more sense. Where it pays off is a spare room in regular use, or one doubling as an office where the bed gets slept in often. The medium soft feel gives visitors a genuinely comfortable night, and you can compare the retailers listed on this page for the current price.
