Why should you choose this mattress?
If you're set on a Millbrook and want their pocket sprung construction in a wider choice of sizes, this model covers the full spread from UK Small Single to UK Super King, which makes it easier to match an unusual bed frame. The starting price places it firmly in premium territory, so it suits buyers who've already decided to spend more for a traditionally made mattress rather than anyone shopping on price. Ask the retailer directly about delivery, returns and any guarantee before committing.
Key features & layer details
Natural fillings
Deep layers of Hampshire wool, cashgora wool, silk and soft English spun cotton sit on top. These natural fibres give the firm feel a softer, more cushioned surface, though the mattress as a whole stays firm.
Pocket spring interior
The core is 2000 inner pocket springs, with a 1000 and a 2000 tablet comfort layer of pocket springs on either side. Because the springs work independently, you get steady support across the bed, and the double-sided build means it can be flipped and rotated.

Best suited for?
Couples
Six sizes up to UK Super King give two sleepers plenty of width, so a shared bed can be matched to the room.
Combination sleepers
Pocket sprung construction in a firm model suits people who change position, since the springs give a steady, supportive feel across the bed.
Guest rooms
A range running from UK Small Single to UK Super King makes it easy to choose the right size for a spare room.
This isn't one for tighter budgets: it sits well above entry-level pocket sprung options. Buyers who want full published specs up front may prefer a better-documented model.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How much does the Millbrook Wool Sublime Firm Pocket 8000 cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It sits in the premium bracket.
What sizes does the Millbrook Wool Sublime Firm Pocket 8000 come in?
Six UK sizes are listed: Small Single, Single, Small Double, Double, King and Super King. That's a broader spread than many models offer, which helps if you have a smaller guest bed or an unusual frame to fit.
Does the Millbrook Wool Sublime Firm Pocket 8000 have 8000 springs?
Not necessarily. The 8000 in the name is part of Millbrook's model branding rather than a confirmed spring count, and we don't hold a verified figure for this mattress. If the exact count matters to you, ask the retailer to confirm the specification.
What trial and guarantee comes with the Millbrook Wool Sublime Firm Pocket 8000?
We don't hold verified trial, returns or guarantee terms for this model. Any trial or guarantee will depend on where you buy, so confirm the details with the retailer before ordering, ideally in writing.
