5 Things to consider before buying an Ergonomic Chair! 

1. Adjustability: The Height of the Seat and Arms should be adjustable for all Ergonomic Chairs as a standard feature. In addition, an Adjustable Lumbar Support to promote good sitting posture is also valuable. Being able to adjust the Angle of the Seat, as well as the length of the seat, are preferred adjustments to ensure a correct fit. The width and Height of the arms will offer complete ergonomics and comfort. 

2. Lumbar Support: Lower back support in an ergonomic chair is very important. The lumbar spine has an inward curve, and sitting for long periods without support for this curve tends to lead to slouching (which flattens the natural curve) and strains the structures in the lower spine. An ergonomic chair should have a lumbar adjustment (both height and depth) so each user can get the proper fit to support the inward curve of the lower back. 

3. Seat Material: The materials on the office chair seat and back should have enough padding to be comfortable to sit on for extended periods of time. Choosing a chair with Extra Padding & a Moulded Seat, provide extra comfort. 

4. Weight Rating: The Weight Rating is particularly important to ensure the chair is robust and built specifically for the user. A chair that is rated below a user's weight will void warranty and be potentially unsafe for the user.  

5. Warranty: 3 Year Warranty on an Ergonomic Chair is a must, however 5-10 Year warranties are preferred to ensure the advertised features of the chair have gone through rigorous testing to ensure longevity.
