Layer Details
- Cover. A fine English cotton cover, spun and crafted in the North West of England. Cotton is soft against bedding and breathable, which helps keep the sleep surface fresh.
- Comfort Layer. Sustainably sourced Hampshire wool provides the cushioning here, and it's known for durability and elasticity. That means a comfort layer that should keep its feel over time rather than flattening quickly.
- Support System. A 7-zone ergonomic pocket spring system with 1000 individually responsive springs. Each zone is tailored to a specific area of the body, so you get softer comfort at the shoulders and firmer support at the hips and lower back.

- Fits compact rooms: 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.
- Firm support for growing sleepers: The 7-zone pocket spring system gives firmer support under the hips and lower back, which suits teenagers moving up from a childhood bed.
- Wool keeps the surface fresh: Hampshire wool under a cotton cover regulates temperature naturally, useful in a guest room where you can't predict whether visitors run warm.
- Suits raised frames: At 25cm deep, this single sits sensibly within the guard rails of most bunk and mid-sleeper frames, though check your frame's maximum mattress depth first.
- Cheap, easy bedding: Standard single sheets and duvets are the most widely stocked of any size, which keeps a spare room or student flat simple to kit out.
This size suits you if...
You're buying for a child or teenager and want a firm, natural-fill mattress that will hold its shape through years of growing, or you're furnishing a guest room or a spare room that doubles as an office and need a bed that doesn't dominate the floor. It also suits a student room or first flat where the frame is provided and only the mattress is yours to choose.
Consider another size if...
You're an adult who shares the bed regularly, or you simply want more room to stretch out. We'd recommend the UK double instead, which is 45cm wider, gives 67.5cm each for two sharing, and needs at least 2.6m x 2.8m of floor space.

What size is the Millbrook Regent Wool Ortho UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits standard single bed frames, bunk beds and mid sleepers without any adjustment, and standard single bedding fits it straight away.
Will the Millbrook Regent Wool Ortho single fit a bunk or mid sleeper?
The UK single is the standard size for bunk and mid-sleeper frames, so the footprint will fit. The one thing to check is depth: this mattress is 25cm deep, and raised frames set a maximum so the guard rail still does its job. Check your frame's limit before ordering.
What room size do I need for a single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk round the bed and open drawers or wardrobe doors, which matters in a child's room competing with toys and a desk, or a loft room where the slope narrows the usable floor.
Is the Millbrook Regent Wool Ortho single a good choice for a child?
For most children and teens, yes. The firm 7-zone support suits growing backs, and the wool and cotton layers breathe better than synthetic foams. One caveat: it's a genuinely firm mattress, so a very light child who sleeps on their side may find it slightly unyielding at the shoulder.
Where can I buy the Millbrook Regent Wool Ortho in a UK single?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them. One practical point: this mattress arrives flat rather than rolled, so if it's heading up a narrow staircase to a loft room or top bunk, measure the route first.
