Adjustable-Height Clean Room Stools


These adjustable-height stools release minimal contaminants to meet clean room requirements. Lower clean room ratings indicate fewer contaminants, with Class 1 clean rooms being the cleanest environments. Without a backrest, these stools fit under tables and workbenches when they’re not needed. Adjust the height using the lever; the air cylinder controls the movement for a quick, smooth adjustment. The seat swivels so that you can work on multiple surfaces without having to stand up.
Choose a seat height range with heights slightly lower and higher than your ideal setting. Stools up to 23" high fit most comfortably when used with standard 30" high work surfaces, such as tables and desks. Stools that are 24"-27" high are sized for use at standing-height work surfaces that are 36" high, such as workbenches. Stools 28" and higher are meant to be used at extra-high counters that are approximately 40" high.
