The 24/7 seating category includes all of our heavy duty chairs and big and tall chairs that also have an added rating that warranties them for 24/7 use (more than the 40-hour work week). These heavy duty chairs are suited for multi-shift environments like hospitals, dispatch or anywhere that work is performed on a 24-hour basis. Chairs from the 24/7 seating category are extremely durable and are also weight rated for at least 300 lbs, some even 500-750 lbs.
Our advice here is to shop for 24 hour chairs that are properly weight rated for the users. Then pick your design. All of our heavy duty seating products have a 'Warranty' tab where you can click to view the factory details.
