Use your Core-Tex Sit
• in the office to improve ergonomics
• for targeted exercises to strengthen the core and pelvic floor muscles
• to keep the lower back mobile and strong
• burn calories while working at the computer
Step 1
Choose your chair. The ideal seated surface for your Core-Tex Sit is on a flat, firm chair with slight
padding or no padding at all. Sloped, contoured or very soft, deep cushioning on the chair will interfere
with motion of your Core-Tex Sit. Larger individuals will find chairs with minimal to no padding to
work best. If using with a swivel chair and/or a chair on wheels, it is recommended that you lock the
chair and wheels so that the chairs motion does not counter the motion of Core-Tex Sit.
