Layer Details
Pillow top
An additional layer of comfort sitting at the very top of the mattress. It adds extra cushioning, which means a softer first feel as you lie down.
Comfort layer
A fine blend of wool, cotton, silk and cashgora. These natural fibres give the surface its soft, cushioned feel.
Support core
Durable ergonomic pocket springs together with Comfonomic micro springs. This is the part that holds you up beneath the softer layers above.

Key benefits
- Leaves floor space free: At 90 x 190cm, or 3ft x 6ft 3in, it fits comfortably in a compact bedroom, and we suggest allowing at least 2.1m x 2.8m of floor space.
- A soft feel that suits lighter bodies: The medium soft rating and pillow top suit children, teens and lighter adults, who should sink in comfortably at the shoulder rather than feel pushed back.
- Steadier sides on a narrow bed: The triple secured border means the edges should feel steadier, which helps on a 90cm wide bed where you spend more of the night near the side.
- Easy to pair in a guest room: Two UK singles side by side let friends or siblings stay over without sharing, and each bed takes standard single bedding.
- Room for a desk alongside: In a spare room used as a study, a UK single leaves space for a desk and chair, so the room can still work as an office between visits.
This size suits you if...
You sleep alone and want a cushioned, softer bed in a small room, or you're furnishing a child's or teenager's bedroom where storage and a desk need space too. It also suits a guest room where you'd like two separate beds rather than one shared one.
Consider another size if...
You share the bed with a partner, or you'd like more room to spread out on your own. We'd recommend the UK small double instead, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Will the Millbrook Smooth Tech 5000 Pillowtop single fit a bunk bed or mid sleeper?
The 90 x 190cm size matches standard UK single frames, but the mattress is 32cm deep, which is deep for a raised bed. Check the frame maker's maximum mattress depth before buying, because a deep mattress can sit too high against the guard rail on a bunk, cabin or mid sleeper.
What room size do I need for a UK single Millbrook Smooth Tech 5000 Pillowtop?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open a wardrobe door, which matters in a child's room or a box room that also holds a desk.
Is the UK single Smooth Tech 5000 Pillowtop long enough for a tall teenager?
The UK single is 190cm long. A teenager who is still growing and already close to that length may find their feet near the end. If length matters more than width, the UK king is 10cm longer, though it needs a much bigger room: we suggest at least 2.7m x 2.9m for it.
Can two people sleep on a single Millbrook Smooth Tech 5000 Pillowtop?
No, a UK single is a one-person size. For two people sharing, the UK double gives 67.5cm each and is the same length as the UK single. We suggest at least 2.6m x 2.8m for a UK double.
Should I choose a UK single or UK small double for a spare room?
A UK single is the better fit if the room also works as an office or you want two beds for separate guests. The UK single is 30cm narrower than the UK small double, which gives one guest more room to spread out but needs more floor: we suggest at least 2.4m x 2.8m.
