The Pillow Comfort Calm includes Solotex™, a British wool fleece and a sumptuous layer of Himalayan allo, kapok and cotton, aimed at offering maximum support. The ReActivePro™ pocket spring system here means that each spring has 6 turns, ensuring the mattress adapts to your specific contours. Edge to edge support- with higher tension springs nearing the edge of the mattress- enables you to make use of more of the sleep surface, as does the hand side stitching. This is a luxury range, aimed at the ultimate in comfort and relaxation.
