Reverb is a flexible and responsive chair built for years of ergonomic comfort. Designed to offer support over both your lower and upper back regions, the adaptable mesh back and waterfall seat design help keep you alert, while effectively distributing the weight of your body. The pneumatic lever and tension control knob fine-tune the chairs height and tilt to personalize Reverb, while the armrests keep your upper-body is well-positioned. Although mesh designs have increased in popularity in recent years, Reverb offers a choice that is both stylish and works admirably well to protect your body from daily stresses. The nylon base comes equipped with five dual-wheeled hooded casters for easy gliding over carpeted surfaces, and the molded foam seat pan comes generously padded for extra comfort.Set Includes: • One - Reverb Office ChairProduct Dimensions: • Overall Product Dimensions: 29.5"L x 25.5"W x 40.5 - 44"H• Seat Dimensions: 21"L x 18.5"W x 19.5 -23.5"H• Base Dimensions: 21"L x 21"W• Armrest Height: 26-30"H• Backrest Height: 19.5"HProduct Features: • Flexible plastic nylon back• Molded padded foam seat• Pneumatic height adjustment• Tilt tension control• Five dual-caster wheels• Sturdy hooded nylon base• Chair Weight Capacity - 330 lbs
