Layers of Platinum Certified Shetland wool and cotton, and a hand-teased horsehair, Platinum Certified Shetland wool and Mulberry silk blend make up the luxurious Stowe Superb mattress. Providing you with sumptuous comfort and support, its upholstered fillings are complemented by two layers of Vi-Spring's durable calico-pocketed Vanadium steel springs, which help to maintain the structure and integrity of the mattress. Each mattress is hand-crafted, finished with three rows of genuine hand side-stitching and covered with the finest Belgian ticking with hand-tied silk tufts. It partners Vi-Spring's Sovereign 1344 divan base perfectly.
