Key benefits
- Leaves floor space free: At 3ft x 6ft 3in, the UK single fits comfortably in a room of 2.1m x 2.8m, so a desk or chest of drawers can still go in.
- Two can fit in one guest room: A pair of UK singles lets a spare room sleep two friends or siblings separately, with a walkway between the beds.
- Medium feel for growing bodies: The medium grade gives some contouring without a sunk-in feeling, which suits most children and teens as they move between sleeping positions.
- Edges that hold up on a narrow bed: On a 90cm wide mattress you spend more time near the sides, and the UniCased XT edge support helps them keep their shape when you sit or roll close.
- Allergy UK endorsed for a child's room: ProShield allergen protection is built in, which means parents of children with allergies have one less thing to add.
This size suits you if...
You sleep alone, or you're furnishing a child's or teenager's bedroom where the bed has to share the floor with a wardrobe and desk. It also suits a spare room that doubles as an office, or a loft conversion where only a narrow bed fits under the slope.
Consider another size if...
You share the bed with a partner, or you have outgrown sleeping solo on 90cm. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for it.

FAQ's
Will the Sealy Antuco UK single fit a bunk bed or mid sleeper?
Check carefully first. The mattress is 34cm deep, which is tall for many raised frames. Look up your frame's maximum recommended mattress depth, and make sure the guard rail still sits well above the sleeping surface once the mattress is on. If the frame's guidance is lower than 34cm, choose a different mattress for that bed.
What are the Sealy Antuco UK single dimensions in feet?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. It's the same length as the UK double, so a tall teenager gains no extra length by moving up to the UK double, only extra width.
How big does a room need to be for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves enough space to walk around the bed and open drawers, and it's why the UK single is a practical choice for box rooms, students' rooms and children's bedrooms.
Is a UK single long enough for a tall adult?
For most adults, yes, but very tall sleepers may find their feet near the end. The UK single is 10cm shorter than the UK king, so if length matters more than room size, the UK king is the size to look at. We suggest at least 2.7m x 2.9m for it.
What bedding fits a 34cm deep UK single mattress?
A standard single duvet (135 x 200cm) fits. For the fitted sheet, look for one described as deep or extra deep, because a standard single sheet may struggle to tuck under a mattress that is 34cm deep.
