What is the weight rating and testing protocol of your chairs?

Nemschoff products are designed and tested to rigorous standards of ANSI/BIFMA X5.4 Lounge and Public Seating.  These standards are intended to provide manufacturers, specifiers, and users with a common basis for evaluating the durability and structural adequacy of lounge and public seating.

Our seating tests include dropping 125 pounds on the seat over 100,000 times and impacting each seat with 225 pounds, which is dropped from a height of six inches.  Additionally, each seat and back is pushed with a lateral force between 250 and 300 pounds simultaneously. Our standard chairs have a weight capacity of 350 pounds. Our Plus Seating is available in extended seat widths.
