(This does not hold true if the user is sitting in the knees-up position with only the "sitting-bones" making seat contact. The pressure will still remain on these bones no matter how deep the seat is. If the thighs do not make contact with the seat, they will not aid in an even pressure distribution.)The term Zero Gravity refers to a state or condition in which there is no (apparent) force or stress acting on a body. Ideally this would mean that the force of gravity is not acting on a body, but since that is only achievable in space, in realistic terms this means that the body is not under any stress because forces are evenly distributed across it. A detailed comparison of zero gravity chairs has been done by ComfortBro . The zero gravity massage chair took the market by storm nearly a decade ago, but do you really know how they work?

The ergonomic chair is not only unsafe, because of casters that don't lock; but the seat can also move with a swivel device. This presents another danger, as there needs to be a locking device for securing the seat, before transferring out of the chair.

Furthermore, it is a horrible experience to sit on an office chair without any back support. It is very uncomfortable to sit in a chair that does not provide rest to your neck and back. Also, such a chair is a great threat to the lower back of the employee along with his neck and spinal cord. So, office chair back support is a must for employees to ensure that they are healthy and active. With a proper back rest, employees do not feel tired easily and their efficiency at work also increases tremendously.
