The workpro chair range is manufactured by Office Depot, founded in 1986 in Fort Lauderdale, Florida. 

This company has received recognition for its outstanding quality and service within the office furniture market.

In this article, we will be looking at two of the models of the Workpro Quantum, namely the 9000 and the Workpro 12000 to compare them head to head, giving you the facts to make your decision easier when you want to buy the best office chair.

Breaking it down

The following features of the Workpro Quantum 9000 and the Workpro 12000 are exactly the same:

  • The maximum weight capacity
  • Suitable to use for 8 to 10 hours
  • Both chairs have lumbar support, seat glide function, swivel, a waterfall seat design and rollers
  • Adjustable arm height and pivot functions 
  • Limited lifetime warranty
  • No massage options
  • Eco-conscious choice 
  • Both require assembly

For purposes of this comparison, we will be looking at the maximum weight capacity of the chair, the seat height adjustment, the specs of the seat itself as well as the specs of the back and its adjustability. 

Comparison will also be drawn between the materials used, ergonomics and adjustability.

Lastly, the price, warranty and customer satisfaction rating will come into play.

Maximum Weight Capacity

For any person buying an office chair, one of the most important aspects to consider is that it should support their weight comfortably. 

Buying an office chair is an investment that you want to last, therefore, you are looking for durability and strength.

The Workpro Quantum 9000 is designed to comfortably support the weight of a 275 lbs person.

This is the same for the Workpro 12000, resulting in a tie when it comes to maximum weight capacity.

Seat height adjustment

Seat height adjustment comes into play for comfort because you should be able to place your feet next to one another and then find the perfect height for your legs to form a 90-degree angle with the floor. 

Chairs without the feature to set seat height adjustment to your required needs, is a poor option.

The Workpro Quantum 9000 seat height can be adjusted between 37.5 and 43.75  inches.

This allows for about a 6 inch adjustability range.

For the Workpro 12000 the seat height adjustment range between 19.29 inches and 22.8 inches, allowing only for about 3 inches of adjustability.

As the Workpro Quantum 900 has a bigger adjustability range, it is the winner.

Seat dimensions

The seat dimensions of a chair are one of the basic selling points. 

Even if you are a larger person, the size of the seat will determine your comfort when sitting for long hours. 

A smaller person can sit in a larger chair while a larger person will be uncomfortable in a smaller chair.

The Workpro Quantum 9000 has a seat length of 20.5 inches and a width of 19.25 inches. 

It is made from mesh with a waterfall design edge, so as not to cut off blood circulation.

The 12000 has a standard padded seat that may be more ideal for sitting for longer hours. 

It also has the same waterfall design. 

However, the seat length is 15.5 inches while the width is 20.06 inches.

A larger seat dimension makes provision for a bigger variety of workers, making the Workpro Quantum 9000 the winner.

Back height and backrest adjustment

In any office chair, the back height adjustment is a very important feature. 

A chair back above your shoulders will be extremely uncomfortable. Both chairs are described as mid-back chairs.

The Workpro Quantum 9000 has a back height of 20.67 inches and the back height is adjustable to fit your specific body type and height.

The Workpro 12000 back height is not specified, but it is higher than its rival.

You have to sit in this chair and see if it is a perfect fit before you buy it.

The higher level of adjustability of the backrest, makes the Workpro Quantum 9000 the preferred option.

Materials

The materials a chair is made of, will determine the look, feel and quality of the chair. 

Mesh is a breathable material while fabric may have a softer feel.

The Workpro Quantum 9000 is made from mesh material for both the back and the seat. 

This durable material has medium firmness that offers just enough support without resulting in a sinking feeling.

The cooling effect of the mesh is usually preferred by larger people.

For the Workpro 1200, the material is a combination of mesh for the back and fabric for the seat. 

This results in the padded seating feeling softer, especially for the larger people and for people that sit for long hours. 

The choice of material is usually influenced by personal taste, but the Workpro 1200 wins by a small margin.

Ergonomics and adjustability

Adjustability and ergonomics are all about comfort and customising the chair for the individual’s personal preferences.

The adjustability of the Workpro Quantum 9000 is one of its main strengths.

The arm height and width, back angle, seat back depth, seat height, synchro tilt and tilt angle with tilt lock as well as the tilt tension can be adjusted.

This chair is very comfortable, especially if you suffer from spinal or tailbone pain. 

The Workpro 12000 is an ergonomic chair where the arm height, back angle, seat back depth, tilt angle and lock can be adjusted and is also very comfortable.

The Workpro Quantum 9000 wins this category.

Price

Budget and price will always play a role when buying a product. 

When you buy multiple units, the price difference comes into play even more profoundly.  

The Workpro Quantum 9000 sells at $550 while the Workpro 12000 is sold for only $80 more at $630.

Both chairs are affordable, but the Workpro Quantum 9000 is the cheapest.

Customers reviews

On Amazon.com, the rating for the Workpro Quantum 9000 is 4.6 out of 5, rated by 590 customers and 78% gave it a 5-star.

The Workpro 12000 rated an average of 3.6 out of 5 from 8 reviews where only 61% of participants gave it a 5-star.

The Workpro Quantum 9000 is the more popular chair and the clear winner.

The Workpro Quantum 9000 is a durable, heavy 60-pound chair and very popular with the S-shape backrest with lumbar support.

It has no backrest, but comes at a very affordable price.

The Workpro 12000 is highly adjustable with excellent lumbar support and is also still reasonably priced, although a little more expensive.

The headrest is a nice addition to the chair.

Final Verdict

Both products are excellent buys, but in terms of popularity and price and also taking into account the more comfortable seat size, the best office chair to buy between the two will be the Workpro Quantum 9000.
