Comfort fillings
A blend of wool, silk, cashgora and cotton, which means a breathable, temperature-regulating sleep surface. Natural fibres like these tend to wick moisture better than foam.
Mini Pocket Springs
4000 mini pocket springs sit near the surface for added comfort and pressure relief. They also decrease motion transfer, so you feel less of a partner's movement.
Pocket Springs
1000 traditional pocket springs, each enclosed in its own cloth pocket. They respond independently to movement, which means support that follows your shape rather than pushing back as one unit.
Border reinforcement
The edge is reinforced with butterfly springs and secured with a rod frame. That means firmer edge support, useful for sitting on the bed or sleeping close to the side.
