Adjustable-Height Swivel Stools with Backrest













These adjustable-height stools rotate so that you can work on multiple surfaces without having to stand up. A backrest provides support and promotes good posture to reduce back strain. Often used in demanding shop environments, these stools have a durable construction.
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. Stools with lever adjustment have an air cylinder for quick, smooth height adjustment. For stools with threaded rod adjustment, turn the seat to adjust the height.
Stools that tilt allow you to adjust the angle of the seat. By tilting the seat forward, you promote good circulation in your legs.
Polyurethane stools resist stains, grease, water, and chemicals better than all of these materials. Vinyl and fabric stools have padding in the seat and backrest for comfort. Vinyl is easier to clean than fabric.
