Has anyone bought one of these black leather chairs, with a chromed, rather stiff, side-mounted release handle. Made abroad for Argos group, but not found on the thick Argos catalogue. The price and 5-mile delivery charge seem reasonable. Are they really up to regular activation and closing? - as the catch of the single one of the two models on display in our Orpington store has already become faulty, in only a few days, and handle won't activate. Thanx Jim
