Damask cover
A damask cover, hand side stitched with a tufted finish. It gives a smooth, finished surface and keeps the fillings held in place.

Cashmere, wool and silk layer
A natural-fibre layer of cashmere, wool and silk at the surface. It gives the mattress a soft feel under you.

Wool and cotton comfort layer
A comfort layer of wool and cotton fibres, with soft polyester fibres. It adds cushioning between the surface and the springs.

Mini pocket springs
4,000 mini pocket springs (king size count) near the surface. They add a responsive layer of give that moves with you.

Pocket springs
1,000 pocket springs in individual fabric pockets (king size count), with two wire rods in the border. The springs support each part of your body separately, and the rods help the edge hold up when you sit or sleep near it.
