Why should you choose this mattress?
This is a firm, traditional pocket spring mattress with natural fillings, so it suits people who want a flat, supportive feel rather than a soft sink. Each spring sits in its own cloth sleeve, and the comfort layers on either side of the central springs are also pocket spring. The fillings include Hampshire and Cashgora wool, silk and English spun cotton, which are natural materials. Air vents allow airflow. It's double sided, so you can flip and rotate it to help it wear evenly. It will probably suit back sleepers best, although lighter side sleepers may find a firm feel a little unforgiving.
Key features & layer details
Central pocket springs
A core of 2000 pocket springs, each housed in its own cloth sleeve. This gives the mattress its firm, supportive base, with each spring working on its own rather than moving as one.
Pocket spring tablet comfort layers
Three layers of 1500 pocket spring tablets sit on either side of the core. Because both sides are built the same way, you can flip and rotate the mattress to help it wear evenly.

Back sleepers
