Why should you choose this mattress?
This is a natural-filled, double-sided mattress, so it suits you if you like wool and cotton rather than foam. Hampshire wool, cashgora wool, silk and English spun cotton sit over pocket springs, and the hand-tufted finish and hand side-stitched border point to careful making. You can flip and rotate it, which helps you spread the wear, and the reinforced handles make that easier. The feel is soft to medium, so it should suit side sleepers and anyone wanting a gentle, cushioned feel. Heavier sleepers or those who like a firm bed may find it too yielding. At 33cm deep it is a thick mattress, so check your bed frame and bedding before ordering.
Key features & 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.

Best suited for?
Side sleepers
The soft to medium feel and cushioned wool and cotton fillings give gentle comfort, which suits anyone who sleeps on their side.
Eco-conscious buyers
Natural fillings of Hampshire wool, cashgora wool, silk and English spun cotton are used instead of foam, giving a natural-filled mattress for those avoiding synthetic materials.
Couples
Individually sleeved pocket springs move independently, so the mattress can respond to each person's body, while the double-sided design lets you flip and rotate it to share the wear.

FAQ's
How much does the Millbrook Wool Sublime Soft 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 towards the premium end of the market, so it's sensible to confirm the full specification with the retailer before committing.
What sizes does the Millbrook Wool Sublime Soft Pocket 8000 come in?
It's available in six UK sizes: Small Single, Single, Small Double, Double, King and Super King. That covers most standard UK bed frames, although if you have a European or non-standard frame, measure carefully before ordering.
Does the Millbrook Wool Sublime Soft Pocket 8000 have 8,000 springs?
Not necessarily. The 8000 in the name is branding rather than a confirmed spring count, and we don't hold verified construction details for this model. Ask the retailer for the actual specification if the spring count matters to you.
