Our leathers may have distinct surface characteristics, natural markings, and colour variations which differ from hide to hide and from one product to another, making each leather product unique.

Injection-moulded spring clip supported by a 9-Gauge Sinuous Spring System. Plastic bumpers on all legs to prevent floor damage. All joints have been stress tested. Manufactured to meet California TB117-2013 fire safety standards without the use of flame retardant additives in the upholstery foam. CARB (California Air Resources Board) Phase II compliant.
