We bought a lafuma chair for my wife at last years Peterborough show and the elastic has snapped allready. Is she especially heavy? no. On reading lafuma website it suggests that Elastic Cords: The lifespan of elastic cords used to suspend the fabrics on many Lafuma chairs varies according to use and weather conditions. Cords should generally be replaced every two years or when they show any sign of wear. Lafuma lacing cords can be purchased from the ‘Spare Parts’ area of our site or from your Lafuma stockist. I didnt expect this! bi-annual service on a chair??? Jon btw, its also difficult to fold and quite heavy.
