Comfort fillings
Wool, cotton, hemp and soft white fibres, finished with tufted layers, give natural insulation and help regulate temperature. For you, that means a breathable, foam-free top that should feel less clammy than a dense synthetic surface.
Support system
3750 individual pocket springs sit in cloth pockets, so each spring works on its own. This gives more tailored support to each part of your body, with the firm, no-sink feel the mattress is known for.
