Why should you choose this mattress?
This is a medium-feel pocket spring mattress built around natural fibres, and it suits sleepers who want a balanced, supportive feel. The cover and fillings include Hampshire wool, Cashgora wool, silk and English spun cotton, and air vents help airflow. The springs sit in individual cloth sleeves, so couples should notice less disturbance when one of you moves. It's double sided and can be flipped and rotated, with turning handles on the border, which helps you spread wear over time. The hand tufted finish and hand side-stitched border point to careful making. The downside is that a medium feel may not satisfy anyone who likes a very firm or very plush bed.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
Side sleepers
A medium firmness, as the name says, gives a balance of cushioning and support that suits resting on your side.
Back sleepers
Medium firmness is a middle-of-the-road feel, which means your back gets support without the mattress feeling too hard or too soft.
Combination sleepers
The medium feel sits between soft and firm, so it should be comfortable whether you start on your side or roll onto your back.
Couples
Pocket springs, as the name indicates, move independently, so one person turning over is less likely to disturb the other.
