The Woolacombe Superb is upholstered exclusively in Platinum Certified British fleece wool, including hand-teased local Devonshire fleeces. The combination of these fillings creates a unique, indulgently cosy and supple feel. The use of British wool – with its unique strength, resilience and ability to regain and maintain its form – delivers a sensation of comfort and luxury. Natural materials inherently wick moisture away during sleep to keep you cool and comfortable through out the night, while ensuring your sleep space stays fresh feeling and hygienic throughout its lifetime. Pocketed vanadium steel springs help to maintain the structure and integrity of the mattress, while offering responsive and effective support for your entire body. Each mattress is finished with three rows of genuine hand side-stitching and hand-tufted felt washers. Alternative mattress tensions are available in store.
