The Fellowes Professional Series Ultimate Back Support has been ergonomically designed to help reduce overall back tension and discomfort, by maintaining the stress free lumbar curve of the lower back. The three Memory Foam sections conform comfortably to the body’s curvature, whilst the mid spinal support promotes good posture. The Fellowes Professional Series Ultimate Back Support features a patented Tri Tachment system, which allows the back support to easily attach to any office chair, and to be quickly adjusted to suit the individual user’s needs. Having undergone extensive ergonomic testing the Professional Series Ultimate Back Support has been accredited in line with EU health and Safety legislation, in addition to FIRA an independent international ergonomic consultancy body. Sitting in a chair without proper support can cause poor circulation, back discomfort, and overall fatigue. If your chair does not adjust to provide proper lumbar support use a back support with a foot rest to maintain correct posture. Fellowes Professional Series offers functional and superior ergonomic products which encompasses status, functionality and design.
