Layer Details
Pillow top comfort layer
A plush pillow top packed with natural fibres and mini springs, giving a sink-in feel. It means a soft, cushioned surface that eases you into the mattress.
Pocket spring core
1,000 traditional pocket springs form the heart of the mattress, with 8,000 mini pocket springs blended into the comfort filling layers. That gives the medium feel and a supportive base under the softer top.

Key benefits
- Leaves room for the rest of the furniture: At 90 x 190cm, we suggest at least 2.1m x 2.8m of floor space, which leaves space for a wardrobe, a desk or toy storage.
- A cushioned top for one: The pillow top is filled with natural fibres and mini springs, which means a child or guest sinks gently into a soft surface rather than lying on a flat, firm one.
- Edges that hold up in a narrow bed: The reinforced edge with butterfly border springs means the sides should feel steady, which helps on a narrow bed where you sit on the edge to read or get dressed.
- Flexible guest room setup: Two UK singles side by side let you host two friends separately or push them together, a little more adaptable than a single double bed.
- Bedding that is easy to find: Single sheets and a single duvet are among the most common bedding sizes in UK shops, so replacements and spares are simple to pick up.
This size suits you if...
You sleep alone and like a soft-topped bed, or you're kitting out a child's room or a spare room that also serves as a home office and needs to keep the floor as clear as possible.
Consider another size if...
You share the bed, or you sleep alone but spread out and want more room to turn. We'd recommend the UK small double instead; we suggest at least 2.4m x 2.8m for the UK small double.

FAQ's
Will the Wentworth Mercer Premium 9000 UK single fit a bunk bed or cabin bed?
Possibly not. The mattress is 34cm deep, and raised frames such as bunks, cabin beds and mid sleepers usually state a maximum mattress depth so the guard rail stays high enough to be safe. Check the frame maker's guidance before buying, because a mattress this deep may sit too high on some raised frames.
What size is the Wentworth Mercer Premium 9000 single in feet and inches?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That is the standard UK single size, so it should fit a standard single bed frame. Measure the inside of an older or imported frame first, as these are sometimes slightly different.
How much room do I need for a UK single Premium 9000 Pocket Pillow Top?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That gives you enough room to walk around the bed and open drawers, and it suits box rooms, children's bedrooms and studies that also serve as guest rooms.
Is the UK single Premium 9000 long enough for a tall teenager?
The UK single is 190cm long, the same length as the UK small double and UK double. If your teenager is already very tall, the UK king is 10cm longer than the UK single, although it needs far more space: we suggest at least 2.7m x 2.9m for the UK king.
Should I get the Premium 9000 in a UK single or UK small double?
Choose the UK single if floor space is tight and only one person sleeps there. The UK single is 30cm narrower than the UK small double, and the two sizes are the same length. We suggest at least 2.4m x 2.8m for the UK small double, compared with 2.1m x 2.8m for the UK single.
