3150 Task Features

Seven Leg Base

Seven legs means a 20% improved 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.

Safety Casters

The 2-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 brake 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.

A spring shock absorber prolongs the life of the caster as well as the chair. The closed construction reduces the amount of dirt and hair getting into the caster, prolonging the life of the caster.

Five Position Lock Tilt

Recline to one of five desired positions and keep it there with the push of a button.

Seat Height & Depth Adjustment

Our goal is to provide proper ergonomic support for most body types, starting with the 4th-percentile female size (approximately 5’ 0”) up to the 97th-percentile male (approximately 6’ 5”).

Height adjustment is at your fingertips.


You may not notice it in the first 10 minutes, but you may after the first shift. You will certainly notice it after weeks, months, and years of prolonged seating in a Concept Seating chair. You’ll just feel better.

The chair in which you've been sitting, with its Ergo Air Suspension System (EAS2) has kept the blood and oxygen flowing through your body, especially through the lower extremities, improving blood flow and increasing oxygen levels to tissues.

Adjustable Armrests

Easily adjust the width of the armrests to accommodate a larger person or a person with a duty belt just by sliding out the arms.

Adjustment is made by loosening the thumb screw and adjusting to the desired width. Adjustable to 2.5” on both sides.

Adjustable Lumbar Support

Infinitely adjustable lumbar support puts back pressure relief at your fingertips. Adjustable back insures lumbar is exactly where you want it.

Adjustable Backrest Height

This model also features a height-adjustable backrest. Raise or lower it to one of 6 positions to fit your body type and fine-tune the lumbar support.

2:1 Recline Ratio

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.

Tilt Limiter

Limit recline range while maintaining freedom of movement.

Replaceable Covers

Extend the life of your 24/7 chair within a matter of minutes - make your chair new again by replacing the cover.

The 3142r1 coverset is all-in-one, with a single cover fitting the headrest, backrest, and seat. Industrial strength hook-and-loop attaches the cover to the chair.

3150 Task Options


Easy to put on and take off, and made with a breathable, stretchy athletic fabric which is machine washable.

These Slipcovers thrive in multi-shift environments by preventing the sharing of mess and bacteria between employees. Workers can each use their own Slipcover and take it home at the end of the day.

Partial Footring Base

Provides a ledge on which shorter users can rest their feet without alienating taller users, who can simply rotate the ledge out of the way.

This additional accommodation means nearly all body types can use the same chair.

Swing Armrest

Swing Arms provide a large, comfortable arm pad and increased adjustability.

In addition to the standard height and width adjustments, the arm pads themselves also adjust fore and aft, as well as in and out. Moreover, the arms will fold completely out of the way at the touch of a button.
