Layer Details
Knitted cover
A soft knitted finish that adds cosiness and warmth. Knitted covers enhance airflow, so the surface should feel comfortable without trapping too much heat.
Pillow top
An extra layer of plush wool and cotton fillings, tufted to hold them in place. It gives the surface a softer, more cushioned feel without changing the medium rating.
Mini pocket springs
Small, individually cased springs that add comfort and reduce motion transfer. You get a gentler feel and less disturbance from a restless partner.
Pocket springs
Individually cased springs in cloth pockets that adapt to your movement. They spread support to each part of your body as you shift position.

Key benefits
- Room to spread out alone: At 30cm wider than a UK single, a solo sleeper can turn over and stretch across the plush pillow top without ending up near the edge.
- Suits compact double rooms: We suggest at least 2.4m x 2.8m, so it can work in a box room or loft conversion where a UK double would leave little space to walk around it.
- Calmer for occasional sharing: The mini pocket springs reduce motion transfer, which means a visiting couple sharing for a weekend should disturb each other a little less when one of them moves.
- Support right to the sides: Millbrook adds a reinforced edge, which helps on a narrower bed because you tend to use more of the surface close to the border.
- Easy bedding: The UK small double is a standard 4ft size, so fitted sheets are simple to find and a standard double duvet covers it comfortably.
This size suits you if...
You sleep alone and have outgrown a single, perhaps as a teenager whose room can't spare more floor, or you're furnishing a compact guest room where a couple will stay now and then but nobody sleeps every night.
Consider another size if...
You share with a partner every night, as two adults find 120cm tight over the long run. We'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m.

FAQ's
Is the Millbrook Wool Luxury 1500 Pocket Pillowtop small double big enough for two?
For the odd weekend, yes. The mini pocket springs reduce motion transfer, so a guest couple should feel less of each other's movement. For nightly sharing, a UK small double is snug for two adults, and the UK double, which gives 67.5cm each, would suit you better.
What room size do I need for a UK small double Millbrook mattress?
We suggest at least 2.4m x 2.8m. In a loft conversion with a sloping ceiling, check you can still stand and get in and out of bed on the side you use, then compare the retailers listed on this page.
Small double or double: which Millbrook Wool Luxury 1500 Pocket Pillowtop should I choose?
The UK small double is 15cm narrower than the UK double and the same length. If you sleep alone in a smaller room, the UK small double gives plenty of space without crowding the floor. If two of you share nightly, the UK double gives 67.5cm each and needs at least 2.6m x 2.8m.
What bedding fits a 4ft Millbrook pillowtop mattress?
Use small double fitted sheets, and a standard double duvet covers the bed well. The mattress is 30cm deep with its pillow top, so look for deep fitted sheets that are made for that depth. A shallow sheet may pull off the corners.
Is a UK small double Millbrook mattress a good upgrade for a teenager?
It's a sensible step up from a single. It's 30cm wider than a UK single and the same length, at 4ft x 6ft 3in, so it gives a growing teenager more room to spread out without taking much extra floor. The medium rating with a cushioned pillow top suits most young sleepers.
