Assessed from mattress data provided by our UK retail partners, captured September 2026, and from regular price comparison across those retailers.
Price is the clearest reason to shortlist this one. Starting at £435.76 and topping out at £768, it sits at a fairly accessible point for a pocket sprung mattress, and the spread across sizes is modest rather than steep. The six-size range, including the less common Small Single and Small Double, is helpful if you have an awkward bed frame to fit. We can't tell you how it feels to sleep on or what's inside beyond the pocket springs, so this is a shortlist candidate rather than a confident recommendation until fuller details are confirmed.

How much does the Millbrook Wool Sublime Pocket 3000 cost?
Prices run from £435 to £768 depending on the size you choose, with the cheapest option starting at £435.76. It's currently listed with one retailer, so it's worth comparing sizes there to see where your budget lands.
What sizes does the Millbrook Wool Sublime Pocket 3000 come in?
It's available in six UK sizes: Small Single, Single, Small Double, Double, King and Super King. That includes the two smaller in-between sizes many brands skip, which is handy for guest rooms or compact frames.
Is the Millbrook Wool Sublime Pocket 3000 a pocket sprung mattress?
Yes, it uses pocket springs, which move independently of one another, meaning less disturbance when a partner shifts in the night. We don't currently hold a confirmed spring count or details of the comfort layers, so check the retailer listing for the full specification.
