Layer Details
Pillow top
A luxuriously plump pillow top sits on the surface, which means a softer, more cushioned first feel before you reach the supportive layers beneath.
Damask fabric
The mattress is wrapped in soft-touch damask fabric. It gives the sleeping surface a smooth, gentle finish against bedding.
Silk and mohair blend
A silk and mohair blend brings sumptuous softness and helps regulate temperature. In practice that means the mattress should feel less clammy if you run warm at night.
Platinum 3D polyester
This Platinum 3D polyester layer is fully recyclable at the end of its life, a small but genuine environmental plus for a mattress in this bracket.
Pocket springs
Individually wrapped pocket springs distribute body weight evenly for head-to-toe support. Because each spring moves independently, you should feel less disturbance when a partner shifts position.

- Fits where space is tight: At 90cm wide it leaves room for a desk, wardrobe and walkway, which matters in a loft conversion or a bedroom already competing with storage.
- Guest rooms done properly: A pillow-top single with natural fillings gives visitors a genuinely comfortable night, rather than the thin, springy mattress spare rooms usually get.
- Grows with a teenager: The medium-firm tension suits side, front and back sleepers, so it works as a teenager's sleeping style settles rather than needing replacing in a couple of years.
- Cooler for warm sleepers: The silk and mohair blend helps regulate temperature, useful in a small room that heats up quickly on summer nights.
- Easy, cheap bedding: Standard single sheets and a single duvet fit, and they are the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for one sleeper: a teenager ready for a proper adult-quality mattress, a student room or first flat where the frame came with the tenancy but the mattress didn't, or a spare room you'd like guests to actually enjoy. Your room offers at least 2.1m x 2.8m, and you want natural fillings and a deep, cushioned feel rather than foam.
Consider another size if...
You're an adult who sleeps starfished, or two of you will ever share the bed. The UK double would suit you better: it's 45cm wider and the same length, and we suggest a room of at least 2.6m x 2.8m for it.

How big is the Feather & Black Boulton in a UK single?
The UK single Boulton measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits any regular single bed frame and takes standard single sheets and a 135 x 200cm single duvet.
Will the UK single Boulton fit a bunk or mid sleeper?
The width fits, but the depth is the problem: at 30cm this is a deep mattress, and most bunks and mid sleepers specify a much shallower maximum so the guard rail still does its job. Check your frame's stated maximum mattress depth before buying. For a cabin or bunk bed, a slimmer mattress is usually the safer choice.
What room size do I need for a UK single Boulton?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk round the bed and open drawers or a wardrobe. That's our own guidance rather than the manufacturer's. In a loft room with sloping ceilings, position the 90cm width under the lowest part and you'll still have usable standing space.
Is a UK single Boulton big enough for an adult?
Yes for most solo adults, though it's snug if you move around a lot in the night. At 90cm wide it's comfortable for one person sleeping fairly still; a restless sleeper may prefer the UK small double, which is 30cm wider and the same length, with a suggested room of at least 2.4m x 2.8m.
Is the Boulton single a good choice for a child's room?
For an older child or teenager, yes: the medium-firm support and 10,000 pocket springs will last through years of growing, and the 90cm footprint leaves space for a desk and toy storage. For younger children it's a premium spend, and the 30cm depth makes the sleeping surface sit quite high on some frames.
