Why should you choose this mattress?
The natural fillings are the main draw. Wool, silk and cotton sit above the springs, so you get a soft, cushioned feel without foam. Air vents help airflow too. Because it's double sided, you can flip and rotate it, which helps spread wear over time. Mini pocket tablet springs on both sides add support and comfort, and the side-stitched border increases the sleeping surface by 20%. Overall it suits side sleepers and lighter sleepers who like a gentle, medium-soft feel, although heavier sleepers may want something firmer. Millbrook gives a 5-year guarantee.

Best suited for?
Side sleepers
The medium soft feel and the cushioned wool, silk and cotton top give some give at the shoulders and hips, so side sleeping feels gentle.
Lighter sleepers
A medium soft rating with soft to medium support suits lighter bodies who want to sink in a little rather than rest on a firm surface.
Warm sleepers
Natural wool, silk and cotton fillings sit above the springs without foam, and air vents help airflow, so the bed is less likely to trap heat.
Eco-conscious buyers
The fillings are natural, using Hampshire wool, cashgora wool, silk and English spun cotton, so you get a soft top layer without any foam.
If you prefer sleeping on a firm mattress, this might not be the best choice. It's rated medium soft, with soft to medium support, so heavier sleepers and back or front sleepers who need a firmer feel may find it too yielding. It also isn't foam, so it won't give the slow, hugging contour of memory foam.
