Layer Details
Viscose cover
The mattress is upholstered in a premium viscose fabric. It forms the smooth outer surface you sleep against, over the natural fillings below.
Natural fillings
Layers of Hampshire wool, cashgora wool, silk and soft English spun cotton make up the filling. They give a natural, cushioned feel without foam, and the mattress is double sided so you can flip and rotate it.
Pocket spring unit with comfort layers
The core has 2000 pocket springs in individual cloth sleeves, with a 1000 and a 2000 tablet comfort layer of pocket springs on either side. The springs move independently, so the mattress can respond to your body, and the extra spring layers add to the soft to medium feel.

Key benefits
- Fits almost any bedroom: At 90cm wide it needs only 2.1m x 2.8m of floor space by our guidance, so a compact room or a loft conversion with a narrow footprint still works.
- A grown-up single: A softer pocket sprung feel in a one-person size suits a solo adult who has no reason to size up but doesn't want an entry-level mattress.
- Full adult length: At 6ft 3in long it's the same length as the UK small double and UK double, so a taller teenager or adult isn't compromising by staying narrow.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding of any UK size.
- Guest room friendly: A single this comfortable makes sense where a spare room doubles as an office, or where two guest beds fit and one double wouldn't.
This size suits you if...
You sleep alone and want a genuinely comfortable mattress rather than the cheapest thing that fits the frame, your room is compact and 90cm of width is all the space allows, or you're furnishing a guest room to a standard you'd be happy to sleep in yourself. It also suits a teenager who has outgrown a children's mattress but not a children's room.
Consider another size if...
You share the bed, or you're a solo sleeper who spreads out and finds 90cm restrictive. We'd recommend the UK double instead: it's 45cm wider, gives 67.5cm each for two sharing, and we suggest at least 2.6m x 2.8m of floor space for it.

FAQ's
What room size do I need for the Millbrook Wool Sublime Soft in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That's our own guidance rather than Millbrook's, and it leaves room to walk round the bed and open drawers. It's the smallest footprint of any standard UK size, which is why a single works in box rooms, lofts and shared children's bedrooms where two beds need a walkway between them.
Is a UK single big enough for an adult?
For one person, usually yes. At 90 x 190cm it's the standard UK one-person size, and it's the same 190cm length as the UK double, so height isn't the issue. Width is the deciding factor: if you sleep on your back with arms out, or turn a lot, you may find 90cm a little tight. Solo sleepers who want more room could consider the UK small double, which is 30cm wider.
Will this mattress fit a bunk or mid-sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames. Depth is the thing to check, though: raised frames often have a maximum mattress depth for the guard rail to work safely, and Millbrook doesn't publish full specifications for this model. Confirm the depth with the retailer and compare it against your frame's stated limit before buying.
What bedding fits the Millbrook Wool Sublime Soft in a single?
Standard UK single bedding: fitted sheets sized for 90 x 190cm and a 135 x 200cm single duvet. Both are the cheapest and most commonly stocked bedding of any UK size, which keeps the running costs of this size low even though the mattress itself sits at the premium end.
Where can I buy the UK single size of this mattress?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them. Because full specifications for this model are limited, it's worth confirming firmness and depth with the seller before you order, particularly if the mattress is going onto a bunk or mid-sleeper frame with a depth limit.
