Layer Details
Central pocket springs
A core of 2000 pocket springs, each housed in its own cloth sleeve. This gives the mattress its firm, supportive base, with each spring working on its own rather than moving as one.
Pocket spring tablet comfort layers
Three layers of 1500 pocket spring tablets sit on either side of the core. Because both sides are built the same way, you can flip and rotate the mattress to help it wear evenly.

Key benefits
- Full support in one-person width: The pocket-sprung build supports independently across the 90cm width, which means a solo sleeper gets proper spinal alignment without paying for space they will never use.
- Fits compact rooms: At 3ft wide it suits a loft conversion with a narrow footprint or a spare room that spends its weekdays as an office.
- A firm feel for adults, too: Firm pocket springs suit heavier solo sleepers and back sleepers, so this single works for a grown-up bedroom rather than only a child's.
- Wool where it counts: Wool in the mix helps regulate temperature, which means a hot sleeper in a small, warm room should stay a little more comfortable.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and both are the most widely stocked bedding of any UK size.
This size suits you if...
You're a single adult who wants a firm, supportive mattress and is happy to pay for pocket springs and natural wool, you're furnishing a guest room where visitors deserve better than a budget spare bed, or you're buying for a teenager who needs firmer support and will use the bed for years rather than months.
Consider another size if...
You're an adult who spreads out in the night, or two of you will ever share it. The UK double gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m of floor space and we'd recommend it instead.

FAQ's
Is the Millbrook Wool Sublime Firm Pocket 11000 UK single big enough for an adult?
For most adults, yes. At 90 x 190cm it's the standard UK one-person size, and the firm pocket-sprung feel suits adult weights better than many children's mattresses. Taller sleepers should note the 190cm length; if you're over 6ft, the UK king adds 10cm of length as well as width.
Will the UK single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames. Millbrook doesn't publish a depth for this mattress, though, and raised frames usually set a maximum mattress depth for the safety rail, so check the measurement with the retailer against your frame's guidance before buying.
Is this a good single mattress for a child's room?
It fits: the single leaves floor space free for a wardrobe, desk and toy storage in even a small bedroom, and firm support suits growing bodies. That said, this is a premium pocket-sprung mattress, and a child may outgrow the room before they outgrow it, so weigh the spend against how long they'll use it.
How much floor space does the UK single need?
We suggest allowing at least 2.1m x 2.8m, which leaves room to walk alongside the bed and open drawers or a wardrobe. That makes it a practical fit for box rooms, lofts with a narrow usable footprint, and guest rooms where you want two beds with a walkway between them rather than one larger bed.
