Safco Pneumatic-Lift Lab Stool Without Back, Black/Chrome

Lift lever adjusts seat to the perfect working height with 1 touch! 1-touch seat-height adjustment for ideal positioning. With a touch of the pneumatic lift lever, you can effortlessly raise or lower your stool anywhere within a 5in range, so you are always at the perfect height for your lab counter, workbench or any other worksurface. Helps you maintain better posture, so you can work longer with less fatigue. Thick seat cushion keeps you comfortable. The generous 3 1/2in padded seat is soft yet supportive, to help ease the strain and discomfort caused by long periods of sitting. Vinyl upholstery for durability and easy cleanup! The seat and back (on stools equipped with backs) are covered with a rugged black vinyl thats tough enough to resist splits and tears and provide years of dependable service. And because it wipes clean with a damp cloth, spills are no problem. Dual-wheel casters, 360 deg. swivel provide mobility! Because these double-wheel casters offer broader contact with the floor than most single-wheel casters, they let you roll quickly and easily from 1 workstation to another. The full swivel makes it easy to pivot between worksurfaces. 5-star base for stability and styling. The 23in-diameter, polished-aluminum 5-star base provides the stability you need to maintain a steady hand at your lab counter or other workstation. Plus, it gives your stool a gleaming, high-tech look that will add flair to your surroundings. Stool with seat back adjusts for added support. On stools equipped with seat backs, the back can be manually raised or lowered with a control knob to provide added support for your upper torso, helping to relieve strain.
