Layer Details
- Cotton and Polyester Comfort Layer. Two layers blending cotton and polyester give a cushioned surface feel. The cotton naturally wicks away moisture while the polyester improves airflow, which means less heat building up as you sleep.
- Soft White Fibres. Two layers of soft white fibres sit beneath the top layer. These are resilient and cushioning, which helps the comfortable feel last longer.
- Pocket Spring Core. A core of 2000 durable steel pocket springs, each encased in its own cloth pocket. Because the springs move independently, support adjusts to each part of your body rather than the mattress compressing as one block.

- Leaves room for everything else: At 90cm wide the UK single leaves floor space for a desk, wardrobe or toy storage, and we suggest a room of at least 2.1m x 2.8m.
- Firm support for one sleeper: Each of the springs moves on its own, which means a solo back or front sleeper gets steady support without a softer patch sagging under the hips.
- Suits a spare room that is also an office: A UK single keeps a guest bed in a study or home office while leaving enough floor space for a working desk and chair.
- Two can sit side by side in a guest room: Guest rooms with a pair of UK single beds can seat two visitors who would rather not share, with a walkway kept clear between the beds.
- Check depth before a raised frame: At 29cm deep this mattress sits higher than many slimline options, so confirm the maximum mattress depth on any bunk, cabin or mid sleeper frame first.
This size suits you if...
You sleep alone and like a genuinely firm surface, you're kitting out a teenager's room or a student flat where floor space is tight, or you want a supportive guest bed for a spare room that also serves as an office.
Consider another size if...
You share the bed, or you're a light child or side sleeper who needs more give. For sharing, we'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m.

Is the Natural Pocket 2000 Ortho single too deep for a bunk or cabin bed?
It may be. The mattress is 29cm deep, which is on the thick side for raised frames, where the safety rail needs to sit well above the sleeping surface. Check the frame maker's stated maximum mattress depth before you order a UK single for a bunk, cabin or mid sleeper.
Is an extra firm single mattress suitable for a child?
It depends on the child. Lighter sleepers press into a mattress less, so an extra firm UK single can feel hard on the hips and shoulders of a young side sleeper. Older children and teens who sleep on their back or front are more likely to get on with it. Some owners also describe it as closer to medium firm.
Will a Wentworth Mercer single fit in a small box room?
The UK single is 90 x 190cm, and we suggest a room of at least 2.1m x 2.8m so there's space to walk around it and open drawers or a wardrobe door. In a loft conversion, place the bed where the ceiling is highest along its full length.
Is the UK single long enough for a tall teenager?
The UK single is 190cm long, the same length as the UK double. The UK king adds 10cm of length, but it is also 60cm wider, so it needs a much larger room: we suggest at least 2.7m x 2.9m for the UK king. For most teens, 190cm is enough.
Can I fit two Natural Pocket 2000 Ortho singles in one guest room?
Often, yes, though two beds need noticeably more floor space than one. Each UK single is 90cm wide, so measure the room with a walkway between the beds. The extra firm feel may not suit every visitor, and lighter guests may find it firm.
