Mesh is a woven material that adheres to a frame, so you sit on the center and the sides of the mesh that are attached to the frame create unwanted pressure and pain. This is known as the hammock effect, and over time you will move around to take pressure off of your pain receptors.

If longevity is your concern—"Are mesh chairs good for sitting all day?" - the answer is affirmative. Mesh chairs, characteristic of their breathability, maintain a cooler seating environment, thereby enhancing comfort during prolonged use.

However, the mesh can stretch and contract more over time, eventually sagging, which can force you to have to replace your seat or the whole chair. Another problem with soft mesh is that it expands and contracts more than hard mesh, thus it doesn't distribute your weight evenly over the entire seat.

Particularly, chairs made from robust mesh tend to last upwards of five years. However, it's important to remember that the durability of the mesh can impact comfort levels. A sturdier mesh might mean a less forgiving sitting experience, but it could extend the lifespan of your chair beyond the five-year mark.
