Natural fillings
Deep layers of Hampshire wool, cashgora wool, silk and soft English spun cotton sit on top. These natural fibres give the firm feel a softer, more cushioned surface, though the mattress as a whole stays firm.
Pocket spring interior
The core is 2000 inner pocket springs, with a 1000 and a 2000 tablet comfort layer of pocket springs on either side. Because the springs work independently, you get steady support across the bed, and the double-sided build means it can be flipped and rotated.

Key benefits
- Fits where space is tight: At 90cm wide it leaves room for a desk, wardrobe and toy storage in a child's bedroom, or a walkway between two beds where siblings share.
- A firm feel that lasts through the teens: The firm pocket sprung build suits a growing teenager better than a soft foam bargain, which means the mattress can outlast several changes of bed frame.
- Guest room friendly: A spare room doubling as an office can take a UK single along a wall and still function as a workspace during the day.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, so replacing bedding costs little and takes no hunting.
- Room guidance you can check: We suggest at least 2.1m x 2.8m of floor space, which most UK bedrooms, including loft conversions with a narrow usable strip, can manage.
This size suits you if...
You're buying for a child or teenager and want a firmer, longer-lasting mattress rather than a budget one, you sleep alone in a compact room where a wider bed would crowd everything else out, or you're furnishing a guest room or spare-room office where the bed has to share the space.
Consider another size if...
You're an adult who moves around at night or simply wants more shoulder room. We'd recommend the UK small double instead: it's 30cm wider, the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

FAQ's
What size is the Millbrook Wool Sublime Firm Pocket 8000 UK single?
It measures 90 x 190cm, or 3ft x 6ft 3in. That's the standard UK single, so it fits ordinary single bed frames, and standard single sheets and a 135 x 200cm duvet will fit it without adjustment.
Will the UK single 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: raised frames often have a maximum mattress depth for safety rails, and Millbrook doesn't publish a depth for this mattress, so ask the retailer before ordering.
What room size do I need for a UK single mattress?
We suggest at least 2.1m x 2.8m of floor space. That allows you to open drawers and walk round the bed comfortably, and it's why the UK single works in box rooms, loft conversions and children's bedrooms where furniture competes for space.
Is the UK single big enough for an adult?
Yes, it's the standard one-person size and a solo adult sleeps on it comfortably. If you're broad shouldered or restless, though, the UK small double gives you 30cm more width at the same length, which makes a noticeable difference night to night.
Where can I buy this mattress in a UK single?
