What is Max user weight?

Max user weight is the heaviest load a seat, chair or desk is designed to carry, given in kilograms. It is a structural rating rather than a comfort one: a chair rated high may still be a poor fit for long sitting, and a lower rating is worth avoiding if you sit near the stated limit. One office chair range in this group is rated at 220 kg, while COLAMY lists 136 kg for its ergonomic mesh chair. Check the figure against your own weight and anything you keep on a desk.
