Workpro Quantum 9000 – Review

WorkPro Quantum 9000

With all the basic specifications of this mid-back chair out of the way, I will walk you through some of the most notable features that you need to look out for.

Build Quality and Construction

The first thing you notice after taking out the chair from the package is how heavy it is. The Workpro Quantum 9000 is extremely stable, not to mention very durable as well. The mesh seat and the bottom tilt plate of the office chair come preassembled.

The entire frame of the quantum 9000 is designed with a durable metal frame to ensure long-lasting durability and a rust-proof design. The chair’s cylinder is made of a single solid piece of metal that ensures enhanced durability and stability for the users. Despite how reasonably priced the product is, it doesn’t contain any plastic parts in this mid-back desk chair.

However, the chair’s all-metal parts make it extremely heavy-weight and difficult to move around and assemble in the beginning. The Workpro Quantum 9000 weighs around 60 pounds, which is slightly heavier than the other chairs in a similar price range, especially with that of the Herman Miller Aeron.

Heightened Adjustable Settings

Workpro has outdone themselves concerning the adjustable settings in the chair. It has a very traditional mesh backrest design, but the wide range of adjustable features makes it stand out from the rest. There are quite a few factors we need to look out from adjustable seat height to the allied lumbar support.

The Workpro Quantum 9000 series’s adjustable functions are very easy to operate, meaning that you wouldn’t have a hard time operating the settings at all.

Seat Depth

The seat depth of the quantum 9000 is extremely adjustable. All you need to do is push the second right-hand side button to recline and adjust the seat depth of the chair between 19-21″, depending on what you like. Ensure that you push forward to look at the depth in the desired position. The adjustable seat depth makes the seating experience comfortable for individuals with longer thighs.


Another feature of this mid-back desk chair that comes with adjustable settings is the backrest. The lack of adjustable lumbar support in this chair is compensated well with the adjustable backrest settings. These features make it ideal for both short and tall users and accommodate the height according to the users’ needs. For the best results, sit on the chair and adjust the backrest height to fit your comfort level.


Another adjustable feature in the quantum 9000 is the armrests with pivot function. It is integrated with the firm and comfortable cushions supporting your arms and preventing the risks of strain on the forearms and the elbows after sitting for prolonged hours. It can pivot 25-degrees inwards and then 5-degrees outwards to support your arms for more comfort.

Tilt Mechanism

While there is not much flexibility and recline to the Quantum 9000, the chair does recline up to 30-degrees using the tension knob present on the side of the chair. There is a separate lock on the left side of the chair that lets you lock the tilt and hold the chair in the position that you feel the most comfortable in.


For any good quality office chair, the one thing that everyone is very skeptical about is the material used for the upholstery of the mesh chair. The mesh material in this chair is extremely comfortable and breathable as well.

Unlike the other mesh chair I have come across, this one has a very comfortable bounce. It is not very firm and painful on the back, which means you will feel like you are sinking into the chair.

What are the Advantages and Disadvantages of the Quantum 9000?

Moving ahead from the general features, the next thing worth noting is this office chair’s pros and cons. Some of the most notable ones include:

WorkPro® Quantum 9000 Series Ergonomic Mid-Back...
  • Lumbar feature provides lower back support for all-day comfort
  • Pneumatic seat-height adjustment enables customization
  • Mesh material improves breathability to keep you cool


  • Provides significant comfort and support for individuals struggling with back pain.
  • It has an ergonomic waterfall edge design for enhanced comfort.
  • It is reasonably priced and brings in a range of amazing adjustable features.


  • The chair is not the best for extremely tall people, especially ones above 6’2″.
  • Customer support is very disappointing.
  • Armrest swivel doesn’t stay in place always.

Are There Any Notable Downsides to Buying the Workpro Quantum 9000?

Even with all the features and functions that the mesh chair comes with, a few downsides can irk the users. The adjustable settings in this chair are pretty profound, but the lack of smoother height adjustments and range is something that several users have been criticizing.

Another factor that some users have mixed opinions about is the material of the chair. The poor quality is what raises questions in the minds of the users around. Some of the fixings also need a little help, but it is pretty much negligible for the kind of price it comes with.


If you struggle with lower back pain and want an office chair that would surprise you, I would highly recommend looking out for the Workpro Quantum 9000. It fares well compared to all the competitors in the same price range. It comes with the weight capacity tested, meaning that you wouldn’t have to settle for a chair that doesn’t live up to your expectations.

For a mesh chair in the $300 range, the build quality and the adjustable features of this chair are worth considering. If you compare it with the high-end office chairs, including Herman Miller’s Aeron, the chances are that it will fall short on some aspects. It lives up to all the claims it makes, which makes it one of the bestselling products.
