Layer Details
Viscose cover
The mattress is upholstered in a premium viscose fabric. It forms the smooth outer surface you sleep against, over the natural fillings below.
Natural fillings
Layers of Hampshire wool, cashgora wool, silk and soft English spun cotton make up the filling. They give a natural, cushioned feel without foam, and the mattress is double sided so you can flip and rotate it.
Pocket spring unit with comfort layers
The core has 2000 pocket springs in individual cloth sleeves, with a 1000 and a 2000 tablet comfort layer of pocket springs on either side. The springs move independently, so the mattress can respond to your body, and the extra spring layers add to the soft to medium feel.

Key benefits
- Made for shared bedrooms: At 135cm wide you get 67.5cm each for two people sharing, which is enough for most couples who sleep reasonably close.
- Fits rooms a king would crowd: We suggest at least 2.6m x 2.8m of floor space, which means bedside tables on both sides remain realistic in an average British bedroom.
- Easy to dress: Double sheets and 200 x 200cm double duvets are sold everywhere at every price point, so a premium mattress doesn't force premium bedding costs.
- Generous for one: If you sleep alone, or share with a cat or dog that claims a corner, 135cm gives you space to spread out.
- Works for guest rooms: A double comfortably hosts visiting couples, so this size makes sense if the mattress is destined for a spare room that earns occasional use from two.
This size suits you if...
You're a couple in a typical UK bedroom where a king would leave little walking room, you sleep alone and want space to stretch out or share with a pet, or you're furnishing a guest room that needs to sleep two comfortably. The double also suits older terraces and tight new build landings, where its 135cm width is easier to carry upstairs than larger sizes.
Consider another size if...
You and your partner both like space, or one of you is a restless sleeper, since 67.5cm each can feel snug. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, and we suggest a room of at least 2.7m x 2.9m for it.

FAQ's
Is the UK double Millbrook Wool Sublime Soft Pocket 8000 big enough for two adults?
For most couples, yes. The UK double gives 67.5cm of width each for two sharing, which has been the British standard for decades. Taller sleepers should note the 190cm length: the UK king adds 10cm of length as well as 15cm of width, so consider sizing up if either of you is over six foot.
What room size do I need for the Millbrook Wool Sublime Soft in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and room to open drawers. In a smaller second bedroom or first flat, where the bed shares space with a wardrobe and drawers, the double is usually the largest size that still works.
Should I get this Millbrook mattress in a double or a small double?
It depends on who's sleeping in it. The UK double is 15cm wider than the UK small double, and both are the same length. For a couple sleeping in it every night, that extra 15cm matters and the double is the better buy. For a solo sleeper in a compact room, the small double frees up floor space.
Will a UK double fit up narrow stairs?
Usually, yes. At 135cm wide, a double is easier to turn on the tight staircases of older terraces and narrow new build landings than a king or super king. This is a pocket sprung mattress, so don't expect it to arrive rolled in a box: measure your stairwell and any tight corners before ordering.
Where can I check the price of this mattress in a double?
Prices vary by size and by seller, so use the live comparison table on this page, which is updated as retailers change their prices. Because published specification detail for this model is limited, we'd also suggest confirming firmness and construction with the retailer before you commit, particularly at this price level.
