The Delta three lever chair is a standrad issue Australian made chair with manual back height, seat tilt and back angle adjustment. The standard chair rating is 120kg. A number of upgrade options are available for this chair including weight rating, back adjustment mechanism and seat size versatility with a seat slide.

For any number of reasons, if you are uncomfortable and finding it difficult to sit for prolonged periods, we would recommend that you do not consider the Delta chair in your selection, alternatively we recommend that to consider a chair from one of our premium task chair range.

The Delta Three Lever Chair is a good allrounder for general office use. A three lever mechanism allows the user to adjust the back angle, seat tilt  and height of the chair. 

The Delta office chair has been a 'go to' product for the corporate and government sector for generic office seating. Generally these requirements have been for the three lever version of this chair.

Please Note: The Delta chair does not have the same level of support and comfort as our premium task chair range. If you are sitting for long periods or are having any problems with sitting, we would recommend that you redirect your selection process to a premium task chair similar to the Taquile, Targa, Theta or Ergo+ range.

If you are looking for a general purpose ‘no frills’ chair either in small or large volume, the Delta may fit your requirements.

Mix and Match to deliver your staff the best outcome

If budget allows, we would always recommend that the best option for any office would be our premium range of task chairs, but if budget is tight you could consider an option of providing a generic chair like the Delta in conjunction with providing a premium chair (with a similar aesthetics) to those who really need it. To the trained eye, the differences in the chairs are noticeable, to the untrained eye, not so much. Please call us on 1800 886 150 if you would like to explore this option further.
