The Core-flex task chair has everything you need to transform every minute of sitting into healthy activity.  It features a multi-density foam seat with the patented Core-flex technology, and a breathable mesh back with adjustable height lumbar support.  The soft-touch arm pads swivel 65 degrees, and the arms are fully adjustable for height and width.  The multi-function tilter mechanism has every ergonomic adjustment except seat depth, and the back angle adjustment accommodates most people in the 5'-4" to 5'-11" range.

Core-flex 30 day satisfaction guarantee: We are confident that you will notice improvements in posture and energy level, and a decrease of back discomfort, after sitting in your Core-flex chair for several weeks.  These benefits are the natural result of keeping your core muscles active throughout the day, rather than sitting motionless with a slouched posture in a normal chair.  If for any reason you are not satisfied with the performance of your Core-flex chair during your first 30 days of sitting, just return it in the original packaging for a full refund.

Chair sizes (Standard, Petite and Tall):  all of our chairs come from the factory to accommodate a sitting height of 18"-21" (floor to seating surface).  If you feel you will need a Petite (generally for those under 5'-4") or Tall (for those 6'-0" and taller) size, please indicate when ordering.

These chairs are made to order at the Lifeform factory in Canada, and shipping time is within 14-21 business days after ordering.  Chair assembly is simple, using seven screws, and takes under ten minutes.
