Layer Details
- Fits compact rooms: At 90cm wide it needs only 2.4m x 2.8m of floor space by our guidance, which leaves room for a wardrobe and desk in most children's bedrooms.
- Full adult length: The 190cm length is the same as the UK small double and UK double, so a solo adult loses nothing on legroom by choosing this width.
- Works where two beds are needed: Two UK singles with a walkway between suit siblings sharing or a guest room set up for visitors who don't share a bed.
- A step up for a child's bed: Posturepedic is Sealy's support-focused range, a more substantial choice for a growing teenager than the budget mattresses often bought for this size.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, the most widely stocked and lowest-cost bedding of any UK size.
This size suits you if...
You're buying for a child's or teenager's room where the bed shares space with storage and a desk, you're furnishing a spare room or student flat for one sleeper, or you're an adult who sleeps alone in a smaller bedroom and wants Sealy's support-led build without giving the mattress the whole floor.
Consider another size if...
You share the bed, or you sleep alone but spread out and your room can take more width. We'd recommend the UK double instead, which is 45cm wider at the same length; allow at least 2.6m x 2.8m for it.

What room size do I need for a UK single mattress?
We suggest allowing at least 2.4m x 2.8m of floor space for a UK single, which is our own guidance rather than Sealy's. The mattress itself is 90 x 190cm, so in most box rooms and loft conversions you'll still have space for a wardrobe or desk alongside it.
Will the Sealy Webber Elevate Ultra single fit a bunk or mid-sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames. Depth is the deciding factor on raised frames, and Sealy doesn't publish one for this mattress, so check the measurement with the retailer and against your frame's maximum before buying. Guard rails need to sit well above the mattress surface.
Is a UK single big enough for an adult?
For sleeping alone, yes. The 190cm length matches the UK double, so height isn't the issue; width is. At 3ft across you have room to sleep comfortably but little to sprawl. Adults who move around a lot at night, or who simply have the room space, tend to prefer the UK double, 45cm wider.
How much smaller is this single than the UK king version?
The UK single is 60cm narrower and 10cm shorter than the UK king, a substantial difference in both directions. If you're weighing the two for a master bedroom, we suggest at least 2.7m x 2.9m of floor space for the UK king, against 2.4m x 2.8m for the UK single.
Where can I compare prices on the Sealy Webber Elevate Ultra in a single?
Use the retailer table on this page, which is updated as retailers change their prices. Availability for this size can differ from the other sizes in the range, so a listing you saw for the UK double won't necessarily match what's offered on the UK single.
