Why should you choose this mattress?
Millbrook rates this mattress firm, so it suits sleepers who want a solid, supportive feel rather than sinking in. The pillow top adds a layer of comfort on the surface, which takes the edge off the firmness without changing the rating. Wool and cotton fillings give a natural-fibre comfort layer, and the 1000 pocketed springs sit in cloth pockets beneath. The reinforced edge has a double metal rod border, so the sides should feel steadier when you sit or sleep near them. Air vents and turning handles are included. Best for back sleepers, although side sleepers who want a soft surface may find it too firm.
Key features & layer details
Pillow top
An extra layer of comfort on the surface for a more cushioned feel. It softens the first impression of the mattress without changing its firm rating.
Comfort layer
A soft blend of Hampshire wool and English spun cotton. These natural fibres add cushioning between you and the springs.
Sprung core
1000 individually pocketed springs, each encased in a cloth pocket. This gives the firm support the mattress is rated for.

Best suited for?
Back sleepers
The firm rating and 1000 pocketed springs give solid, supportive feel, while the pillow top adds a little surface cushioning so it never feels harsh.
Front sleepers
A firm feel from the pocket spring core keeps you lying on top of the mattress rather than sinking in, with the pillow top softening the surface.
Eco-conscious buyers
The comfort layer is a blend of Hampshire wool and English spun cotton, giving a natural-fibre filling, and the mattress is handcrafted in the UK.
Warm sleepers
Air vents are built in, and the wool and cotton comfort layer is a natural-fibre filling rather than foam, which suits those who run warm.
If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It's rated firm, and although the pillow top adds some surface cushioning, the overall feel stays firm. Lighter side sleepers who like to sink in may find it unforgiving. It's also single-sided, so you can't flip it, only turn it.
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.
