2-Step Footrest

The 3150 features a 2-step footrest. This footrest is height adjustable to bring it to your perfect position. It's made of steel to provide solid support and stability.


Our goal is to provide proper ergonomic support for 4% female size (approximately 5’ 0”) to the 97% male (approximately 6’ 5”). Height and depth adjustments are at your fingertips. Recline to one of five desired positions and keep it there with the push of a button. This chair comes with a slight forward tilt. This position can be locked out to prevent the forward tilt. The 2:1 Syncro tilt keeps your knees and legs in an ergonomically correct position while allowing you to comfortably recline. For every 2 degrees of back recline, the seat reclines 1 degree maintaining ergonomic comfort.



Seven Leg Base

Seven legs means 20% ease of movement and more stability over five leg chairs. This is especially important for larger individuals that find moving in their chair difficult. Steel construction with metal strength ring and tested to 10,000lb dynamic load, our base is unmatched in strength and stability.

Dymetrol Suspension

Dymetrol dissipates the occupant's weight over the entire chair surface improving blood flow and increasing oxygen levels to tissues. Improved blood flow and increased oxygen levels improves concentration and productivity and decreases fatigue. Dymetrol conforms to the shape of each occupant, as it almost instantly bounces back to original shape when weight is lifted. No springs eliminates the chances of squeaky or flattened springs.

Safety Casters

Two point stem, shock absorber and special bore construction provides an extremely smooth and quiet swivel and roll not found in standard casters. Once the chair is sat in, the break is released and allows the chair to roll freely. This is important for large people that need to put weight on the arms to be able to sit. Spring shock absorber prolongs the life of the caster as well as the chair. Closed Construction reduces the amount of dirt and hair that can get into the caster, prolonging the life of the caster.


Not a better warranty in the business. 24/7 warranty that covers normal wear and tear for people up to 550lbs for 6 years. Compare to a standard warranty that only covers defects in workmanship and parts.
