Seat height ranges from 18" highest to 13" lowest. Chair may have worn appearance as it is made from salvaged barrels. Supports up to 600lbs. Designed for exterior use, but wood will gray over time if left outdoors. Apply one coat of boiled linseed oil once a year to maintain and replenish original wood texture. Due to the nature of the materials and process of production, final chair may vary slightly from that pictured.
