OFM Model 122 Chair

OFM 122 Chair

Although the OFM Model 122 Sliding Seat Ergonomic Task Chair doesn't meet all the guidelines we laid down for a fully compliant ergonomic office chair as it doesn't have adjustable tilt tension, it passes in all other respects.

To recap tilt tension allows you to set the chair's tilting capabilities to suit your weight. However, unless you are very light framed this may not be an issue and so the OFM 122 Ergonomic Task Chair is worthy of consideration. With that said, let's take a look at the Model 122 Sliding Seat Chair in greater detail as we run through the seat's key features.

OFM Model 122 Task Chair Key Features

Sliding Seat Adjustment

The seat pad of the OFM 122 Ergonomic Task Chair has a slide adjustment mechanism to allow you to set the seat's depth to your own leg length. You simply lift the lever under the left of the chair to adjust the depth. If you are quite tall or conversely a little under average height you will find this feature very useful for maximizing your seating comfort.

Seat Height Adjustment

The control of seat height adjustment is by a standard pneumatic gas lift mechanism and this is operated by a conventional gas lift lever control on the chair's right underside.

Back Height Adjustment

To adjust the back height there is a knob on the rear right of the chair. You simply slacken of the control and raise or lower the back to suit your own comfort level.

Lumbar Back Seat Support

The back incorporates lightly molded foam that helps gives good lumbar support. To gain the full benefit set it to support your lower back when you adjust the seat's back height.

Adjustable Seat Pitch

This enables you to set up the pitch angle between the chair's back and seat pan. You adjust this by raising a lever on the right of the chair and lean back and forth to get the ideal seating angle for your own comfort.

Height adjustable arms

The arms on the OFM Model 122 Sliding Seat Ergonomic Task Chair are height adjustable and give a choice of 7 different height positions.
