Layer Details
Pillowtop
A sumptuous tufted pillowtop with layers of British wool. This is what gives the mattress its soft, sink-in first impression.
Silk, wool, cashmere and alpaca layer
An additional layer of silk, wool, cashmere and alpaca, which means the comfort layers breathe well and regulate temperature rather than trapping heat.
Sustainable fresh fibres
British wool layered with sustainable fresh fibres. This adds cushioning depth between the natural fillings and the springs.
Pocket springs
2000 zoned pocket springs with an additional 1000 mini springs. The zoning means firmer support under heavier areas like your hips, while the mini springs fine-tune the surface response.

Key benefits
- Fits almost any room: At 90cm wide it needs only 2.1m x 2.8m of floor space by our guidance, leaving room for a desk, wardrobe and toy storage around it.
- Soft feel suits lighter sleepers: The Softer build works best for lighter bodies, which means the UK single's typical occupants, children, teens and smaller adults, actually get the cushioning as intended.
- Breathable in a small space: Wool, silk, cashmere and alpaca fillings regulate temperature well, useful in box rooms and loft spaces that run warm in summer.
- Reassuring for children's rooms: The fillings are Allergy UK approved as naturally hypoallergenic, a genuine comfort if dust or dander tends to set your child off.
- No compromise on length: At 190cm it's the same length as the UK double, so a taller teenager isn't losing legroom by staying in a single.
- Easy, cheap bedding: Standard single sheets and a 135 x 200cm duvet fit, the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child or teenager whose bedroom has to fit a desk, wardrobe and the bed itself, you sleep alone in a compact room and want something plusher than a typical single, or you're kitting out a spare room and want guests to sleep on a soft, hotel-style surface rather than an afterthought.
Consider another size if...
You're an adult who finds 90cm restrictive, especially as a soft pillowtop encourages you to settle into one spot. We'd recommend the UK double instead: it's 45cm wider, the same length, and needs at least 2.6m x 2.8m of floor space.

FAQ's
Will the Milldale 3000 UK single fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard bunk and mid sleeper frames, but the depth is the issue: at 32.5cm, the mattress is likely to sit above the guard rail on many raised frames. Check your frame's maximum mattress depth before buying, as most bunks specify something far shallower.
Is the UK single Milldale 3000 a good choice for a child's room?
In many ways, yes. The soft feel suits lighter bodies, the natural fillings breathe well, and the Allergy UK approval is reassuring if dust or dander is a concern. The single footprint leaves floor space free for storage and a desk. It is a premium spend for a child's bed, though the 190cm length means it lasts through the teenage years.
How much floor space does a UK single mattress need?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you a walkway and room to make the bed. That makes it a comfortable fit in box rooms, loft conversions with a narrow usable footprint, and spare rooms that double as an office.
Is a UK single big enough for an adult on this mattress?
For lighter adults who sleep alone, yes, and the Softer build suits that profile well. At 90cm wide you have less room to sprawl, and the plush pillowtop tends to cradle you in one position. If you like to spread out, the UK double is 45cm wider and the same length, so it's the natural step up.
Does the Milldale 3000 in a single work for a guest room?
It's a strong guest room option, particularly where you're fitting two single beds rather than one double. The soft, tufted pillowtop gives visitors a hotel-style feel, and single bedding is cheap and easy to keep spare. Compare the retailers listed on this page, as single sizes are often the least expensive way into this mattress.
