Best Homycasa Office High Back Leather Office Chair Desk Computer Chair, Black 2
What to look for when purchasing an ergonomic office chair:
Seat height: Users should be able to adjust the height of the chair to their feet flat on the floor or on a footrest. Knee should be at 90 degrees, so the hamstrings are parallel to the floor. This helps prevent a toppling and keeps the pelvis in an upright position, which reduces the pressure on the thighs and the knee joints.
Height of the back and lumbar support: Lumbar adjustment device (height and depth) provides the appropriate setting for supporting the curve "S" nature of the spine, in particular the internal curve of the lower back. The user can adjust the chair height again to make sure they have the right support. In addition, a chair-shaped backrest can also provide its own lumbar support.
The depth adjustment of the seat: the seat depth (from front to rear) allow the user to keep back contact with the seat. At the same time, there should be no more than two finger space between the back of the knee and the front of the seat. This allows adequate support for the legs, which reduces the pressure on the back of the calves.recommend Homycasa Office Leather Chair Computercheck price
