Breathable mesh on the mid back and seat helps air circulate so you stay cooler while you work, while the wear-resistant surface holds up to daily use. A high-density sponge cushion distributes weight to reduce pressure during long drafting or computer sessions. The gas-lift seat adjusts from 21-28.5-in high to match taller tables, and the footrest height also adjusts so your legs remain supported. A 25 x 25 x 37.5-45 in frame with ergonomic lumbar support helps your waist stay aligned. A 330-lb capacity, 360-degree swivel seat and universal wheels let you move smoothly between tasks and positions around your workspace.
