Leather and mesh chairs both experience wear and tear over long periods of time and daily usage, in different ways. Mesh is durable and offers a firm support which once adjusted, ensures your preferred sitting position is locked in. Mesh chair fans rave about a floating feeling as mesh softens over time and this combined with the more easily adjustable lumbar support and air flow means you can spend your work days in total comfort.
Leather chairs, on the other hand, tend to not age well in comparison as the leather may crack and show signs of wear. Mesh on the other hand is relatively low-maintenance.
