Abstract: A lawn chair leveling block includes a portable rigid, flat ground-engaging pad designed to support the lawn chair in a level position on a sloped ground surface. The pad is provided with an upstanding elevation block having a deep groove along a top surface, and the groove is designed to cradle a U-shaped leg of the chair. Blind holes positioned in the pad at opposite ends of the elevation block are designed to support individual tubular, vertical chair legs. In addition to being utilized for leveling a lawn chair on a sloped surface, the block prevents a chair leg from sinking into soft soil so as to eliminate the risk of the chair tipping over.
