Layer Details
- Comfort Layer. Sustainably sourced Hampshire wool with fine cotton fibres woven through it, sitting directly beneath you. Wool insulates in winter and breathes in summer, which means a more stable temperature through the night.
- Support System. A core of 1000 steel pocket springs, each enclosed in its own fabric pocket. Because every spring compresses independently, the mattress follows your shape rather than tilting as one surface, which also helps limit partner disturbance.
- Border. Sets of butterfly springs shaped to reinforce the mattress edge, held together by a rod frame. In practice that means firmer edges, useful if you sit on the bed to dress or tend to sleep near the side.

- Fits almost any room: At 90cm wide it needs only around 2.1m x 2.8m of floor space by our guidance, leaving room for a desk, wardrobe or toy storage.
- Wool that suits growing sleepers: The Hampshire wool and cotton layer breathes and wicks moisture, which means a more stable temperature for children and teens who run hot at night.
- Firm edges in a narrow bed: Butterfly springs and a rod frame reinforce the border, so a single sleeper can use the full 90cm width without feeling they might roll off.
- Supportive through the teenage years: The medium firm feel and independently reacting pocket springs give proper spinal support, a sensible choice for a mattress a teenager will keep for years.
- Guest room sense: Springy, breathable and substantial at 28cm deep, it gives visitors a comfortable night without you paying for width a solo guest won't use.
This size suits you if...
You're buying for a child or teenager who has outgrown a starter mattress, you sleep alone and want to keep floor space free in a compact room, or you're furnishing a spare room that doubles as an office and needs one comfortable bed rather than a large one.
Consider another size if...
You're an adult sharing the bed, or a restless solo sleeper who wants room to spread out. We'd recommend the UK double instead, which is 45cm wider and gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m of floor space.

Will the Millbrook Smooth Tech Luxury 1000 UK single fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames. The one thing to check is depth: at 28cm this is a substantial mattress, and raised frames need the guard rail to sit well above the mattress surface. Measure your frame's maximum mattress depth before buying.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you room to walk around the bed and open drawers or wardrobe doors. In a box room or under a loft slope, the 90cm width is the main reason this size fits where nothing larger will.
Is the UK single Millbrook Smooth Tech Luxury 1000 suitable for a child?
Yes, with one caveat. The medium firm pocket spring support and breathable wool layer suit children and teens well, and it should last through the growing years. Very light children may find it slightly firm at first, though a firmer surface is generally better for young spines than a soft one.
Can an adult sleep comfortably on this mattress in a single?
A solo adult gets the full 90cm width to themselves, which is more than the 75cm each a couple gets on a UK king. The reinforced edges help here too, letting you use the whole surface. Broader adults or restless sleepers may still prefer sizing up to the UK small double.
Would two UK singles work better than one double in a guest room?
Often, yes. Two singles at 90cm wide each give guests more personal space than a UK double, and suit friends or siblings who'd rather not share. Each UK single is 190cm long, the same length as the UK double, so check your room can take both beds plus a walkway between them.
