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 products have a 'Warranty' tab where you can click to view the factory details.
