Key benefits
- Small footprint, full support: We suggest at least 2.1m x 2.8m of floor space for a UK single, so a desk or chest of drawers can still sit beside the bed.
- Natural filling for a child's room: The Swaledale wool filling and foam-free build suit parents who would rather keep synthetic padding out of a young sleeper's bed.
- Firm support for one: The firm comfort grade keeps a single sleeper's spine well supported, although a light child who sleeps on their side may find the surface a little unyielding.
- Easy to dress: Standard single sheets and a 135 x 200cm single duvet fit, though at 33cm deep you'll want deep fitted sheets so the corners stay put.
- Two beds in a guest room: A pair of UK singles lets a spare room take two guests who'd rather not share, and each mattress stays on its own frame.
This size suits you if...
You sleep alone and like a firm, natural mattress, or you're furnishing a child's or teenager's room where the bed has to share space with a desk and wardrobe. A spare room that doubles as a study, or a guest room set up with two separate beds, also suits the UK single well.
Consider another size if...
You share the bed, or you sprawl and keep reaching the edges. We'd recommend the UK small double instead, which is 30cm wider; we suggest at least 2.4m x 2.8m for it.

FAQ's
Will the Flaxby Woolcroft 3500 UK single fit a bunk bed or cabin bed?
Possibly, but measure first. The mattress is 33cm deep, which is tall for a raised frame, and many bunk, cabin and mid sleeper beds set a maximum mattress depth so the guard rail stays high enough above the sleeper. Check the frame maker's guidance before ordering.
How much room do I need for a UK single Flaxby Woolcroft 3500?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves enough clearance to get in and out of bed comfortably and still fit a wardrobe or desk, which matters in a box room or a child's bedroom.
Is the Flaxby Woolcroft 3500 single too firm for a child?
It depends on how they sleep. The firm grade gives back sleepers solid support, but a light child who lies on their side may find it a little unyielding at the shoulders and hips. If your child curls up on their side, consider a softer mattress for their single bed.
What sheets fit a UK single Flaxby Woolcroft 3500?
Standard single sheets fit the 90 x 190cm surface, and a single duvet at 135 x 200cm covers it well. Because the mattress is 33cm deep, choose deep fitted sheets so the elastic tucks fully underneath.
Should I get the UK single or UK small double Flaxby Woolcroft 3500?
Choose the UK single if floor space is tight; we suggest at least 2.1m x 2.8m. The UK small double is 30cm wider and the same length, which gives a teenager or adult more room to turn, but we suggest at least 2.4m x 2.8m for it.
