Layer Details

Comfort Layer
A layer of 100% Hampshire fleece wool, locally sourced from Hampshire. Wool is naturally breathable and temperature-regulating, so it helps keep you comfortable through the seasons.

Comfort Layer
Natural English cotton fibres that regulate body temperature and wick away moisture. This means less of that clammy feeling on warmer nights.

Support System
1000 individually hand-nested pocket springs, each encased in its own cloth pocket. Because every spring moves independently, you get tailor-made support and less disturbance from a partner shifting position.

Key benefits

Key Benefits of the Millbrook Wool Ortho 1000 Pocket Small Double Mattress

  • Real stretching room for one: At 120cm wide you get 30cm more width than a UK single, which means you can spread out without stepping up to a full double footprint.
  • Fits rooms a double cannot: The UK small double is 15cm narrower than a UK double, useful in a box room, studio or loft conversion where every centimetre of walkway matters.
  • Firm support across the full width: The 1000 hand-nested pocket springs respond individually, so a solo sleeper using the whole surface gets consistent support wherever they settle.
  • Natural fibres in a small room: Hampshire fleece wool and English cotton wick moisture and regulate temperature, helpful in compact bedrooms that can run warm at night.
  • Manageable to turn at this size: This mattress is double-sided and needs regular flipping, and the 120 x 190cm size is easier for one person to turn than a UK king would be.

Who should buy the Millbrook Wool Ortho 1000 Pocket Small Double Mattress?

This size suits you if...

You sleep alone and have outgrown a UK single but your room cannot take a full double, you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, or you're downsizing and the bed has to suit the new room. The firm feel adds a condition: it works best if you sleep on your back or prefer a properly supportive surface.

Consider another size if...

You share the bed every night, because 120cm is a squeeze for two on a firm surface with little give. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m of room.

FAQ's

Frequently Asked Questions About the UK Small Double

Is the Millbrook Wool Ortho 1000 in a UK small double big enough for a couple?

For occasional nights, yes. The UK small double is fine for guests sharing now and then, and the individually pocketed springs limit disturbance when one person moves. For every night, 120cm is tight, especially on a firm mattress you can't sink into. Couples sharing regularly would be better served by the UK double, which gives 67.5cm each.

What room size do I need for a small double Millbrook Wool Ortho 1000?

We suggest at least 2.4m x 2.8m. That allows walking space around the bed and, importantly for this mattress, room to turn it. It's double-sided and needs regular flipping, so a bedroom where the mattress only just fits will make that routine maintenance awkward.

Is the UK small double a good size for a teenager?

Often, yes. It gives a teenager who has outgrown a UK single an extra 30cm of width without losing much floor space, since both sizes are the same length. One caveat with this particular mattress: it's genuinely firm, so a lightweight teenager who sleeps on their side may find it too hard on the shoulders and hips.

How much smaller is the small double than a standard double?

The UK small double is 15cm narrower than the UK double, and both are 190cm long. That 15cm sounds modest but often decides whether a door still clears the bed or whether there's room for a chest of drawers. If your room comfortably meets 2.6m x 2.8m, the UK double is the safer choice for two.

Where can I buy the Millbrook Wool Ortho 1000 in a small double?
