Premium bedroom and lifestyle retailer Feather & Black is launching the London Collection, a British themed beds range featuring what it describes as the UK’s highest spec mattress.

The collection — manufactured by Harrison Spinks — comprises The Belgravia and The Grosvenor, two mattresses with a spring count of 19,500 and 23,500 respectively.

The Belgravia has up to five rows of hand stitching and The Grosvenor six, with both mattresses stuffed with tree silk, horse hair, cashmere and Egyptian cotton.

Identical fabric used in the uniforms of the Grenadier Guards has been used to upholster The London Collection, while Feather & Black has plans to donate £100 from each bed sold to the Help for Heroes charity.
