Spider Stool

Model # NF1990

Lyon’s Spider Stool has been specifically engineered to maximize comfort! Using ergonomic seating greatly increases productivity in industrial, institutional as well as commercial use. The ergonomically designed padded seat and backrest of these industrial work chairs also helps promote good posture.

The Spider Stool features a weight capacity of 300 lbs. The contoured seat of this industrial desk chair offers maximum comfort as well as durability. Being able to adjust to your chair to match your workstation height will also provide you with increased comfort. Lyon’s industrial work chairs feature an adjustable seat. Easily adjust the seat height from 21 inches up to 31 inches high. The seat should be high enough so your arms form a 90° angle at the elbow or slightly greater. This allows better circulation in the shoulders as well as neck and reduces fatigue in the forearms and hands.

Easily adjust the backrest of the Spider Stool for proper lumbar support. Loosening the knob behind the backrest allows you to adjust the backrest until the curve fits into the small of your back and tighten in place. This reduces pressure on the spinal discs. The depth of the backrest can also be adjusted. Slide the backrest into position in the curve of your spine. Allowing the surface of the backrest to help support upper body weight further reduces pressure on the spinal discs.

The Spider Stool is a polyurethane chair. The seat as well as the backrest can be easily wiped clean in harsh environments. The included chair glides help the chair slide across the floor making it easier to align the chair with your workspace. Increase your comfort even further by adding Adjustable Armrests.
