High-Back Ergonomic Mesh Executive Chair with an upholstered headrest providing additional support. Highly adjustable with ergonomic features tested and approved for office use by a certified physiotherapist. The synchro seating mechanism allows the user to adjust the seat height and fix or free float the angle of the seat and back rest together. An 'anti-shock' mechanism facility prevents the user from being thrown forward when the mechanism is unlocked.
I decided to buy these as I was looking for 3 chairs that were adjustable (to fit 3 very different bodies in size and weight) and the price was right. They are more solid than I expected and think they will last a long time. Easy enough to put together. Very pleased with this purchase!. Vivienne. Matfield Tonbridge, GB. Sun May 31 2020
