Abstract
Abstract A lawn chair which has a wheeled attachment removably mounted thereon at the rear thereof so that the lawn chair can be rendered more mobile and can be especially used as a cart for hauling articles, such as beach equipment, ice chests, athletic gear and the like. The attachment has shaft structure with opposed ends provided with wheels for engaging the ground. The shaft structure is coupled to a lower bracket for attachment to the rear crosspiece of the lawn chair. A strap secured the lower bracket firmly to the upper crosspiece of the lawn chair by an upper bracket which fits over an upper crosspiece of the lawn chair. By cinching the strap, the strap is made taut or placed in tension, thereby removably attaching the lower bracket and the wheels to the lower crosspiece.
