Boss Square Back Diamond Stacking Chair W/Arm In Black Fabric offers a modern-style chair for the home or office. These Boss Office Chairs measure 23.5" W x 23" D x 30.5" H and stack up to four chairs high, which will save space when the seats aren't in use. The powder coated steel frames are extremely durable, and even though the chair is only 18 pounds, it is capable of holding up to 250 pounds. The waterfall seat and tapered legs are designed to reduce stress and the molded arm caps add comfort. The upholstery is made of vinyl, which makes cleaning a breeze.
