3142r1 High Back 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.

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.

Height 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 96th-percentile male (approximately 6’ 5”).

Height adjustment is at your fingertips.

Adjustable Lumbar Support

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


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.

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.

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.

Seven-Position Tilt

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

Cut-Away Sides

Whether your duty belt is a side arm or a radio, the cut away sides allow you to sit more comfortably, allowing most equipment on the duty belt to hang free without poking into your back while seated.

3142r1 High Back Options

Neck Roll

Simply slip the easily adjustable neck roll over the top of the chair and adjust it to the height you need.

Perfect support if you need to monitor a video wall or just want some extra neck support.


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.
