The Stamina InLine Inversion System looks like a padded, upholstered chair, but converts to a flat table as you invert for easy on and off. It adjusts to fit most heights with a height-adjustment beam, and inversion uses your body weight and gravity to stretch and strengthen your back. It has a heavy-duty steel frame construction, leg support adjustment to fit thigh length, quick-adjust footrest for correct positioning to invert, foam-padded ankle support for added comfort and stability while inverted, cushioned, comfortable upholstery, a leg-lock system with a push-button lever release to hold your ankles securely, and padded handlebar assists for easier inversion and return. Skid-resistant rubber floor protectors provide maximum stability and security while you work out.
