Why should you choose this mattress?
Price is the clearest reason to shortlist this one. 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.

Best suited for?
Budget buyers
The copy describes it as fairly accessible for a pocket sprung mattress, with only a modest price spread across sizes, so it is worth shortlisting on cost.
Guest rooms
A pocket sprung build at an accessible price point makes it a sensible shortlist option for a spare room, though fuller details are still to be confirmed.
Couples
The size range includes Small Double alongside larger sizes, and the modest price gap between them helps when you are comparing options for a shared bed.
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.

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.
