Designed to engage your leg, back and core muscles, the VARIChair Pro gives you the freedom to move throughout your day, letting you stay active even while sitting or leaning. Its low back encourages good posture while seated, and it has a wide, cushioned seat supported by a bent plywood seat base. The articulating pedestal offers a wide range of motion, so you can rock or stretch while sitting. If you choose to raise the adjustable-height stool and lean while standing, you can still work your legs, back, and core.
