WorkPro® Quantum 9000 Series Ergonomic Mid-Back Mesh/Mesh Chair, Black

This is basically the entry level to luxury office chairs. Like a Longines or a Seiko. It is absolutely functional in all of the most important ways that a herman miller is - the mesh is comfy and reliable (I've been using it WFH for six years), the back support is excellent and sturdy, the rollers are smooth and the adjustment tools are still in good order six years into daily use. I have basically no complaints about any of the above (as a 5'9" man, 200 pounds). The only noticeable wear on the entire chair is the armrest cushions (not the armrests themselves). The cushion has worn somewhat, but in my opinion that is to be expected. It's just foam and easily the least important part of the overall experience to the chair. The armrest wear only began to show about four or five years in. I'd recommend buying a cheap seat cover, made of cloth to help retain the durability of the seat mesh, but otherwise I only have good things to say about it. It's in the same ballpark as the herman miller aeron in terms of overall feel, but definitely a half-step down. That said, it's also nearly a third of the normal price and absolutely good enough for a daily driver for a WFH professional like myself.

We had 2 of these chairs for over 6 years and they held up amazing. During that time, our two teenagers went through various cheaper brands of chairs... on average they would wear out 1 chair a year. We finally decided to give them our workpro chairs and get new ones for us. These new chairs have a few improved features from the original ones (additional lumbar support and improved arm rests). I love the adjustability for the seat and back position and it is the most comfortable chair I have ever owned. And the old chairs? The kids have had them for over 6 months now and they are still good as new. I know I wouldn't have wanted to spend that much on chairs for kids, but it would have been cheaper in the long run.

**Updated review*** post tirelessly searching for a chair I finally decided on this one because of reviews. I would have preferred the cushioned seat model but not for the price! Shipping-I received the day after I ordered! Chair hugs my body nice. Two things I am really disappointed by 1) is the slight give in the back rest in lock position which prevents your back from being straight which is a feature I prefer. 2) the mesh on the back, towards lumbar is not taut. I feel it should not look like that and that this could be taking away from Back support. Any feedback on that would be appreciated but it is definitely going to be a call to the manufacturer. Overall decent chair however, I did not get the immediate relief or that ah ha moment that I was looking for with this chair. 3/5/23 updated review-- this chair is by far worth the money I paid for it! 1) slight give in the back support took some getting use to but studies show it takes pressure off of your spine. 2) mesh on the back of chair seriously not a big deal that I wrote about previously. The chair is sturdy and the mesh on this chair is top of the line and offers a lot of support.m and comfort. I work from home and sit in this chair 8-9hours a day. I have a Hx of tailbone pain from sitting in desk chairs but not with this chair. The only thing is my bottom gets a little cold but a $5 chair cover solved that problem but it's better than swap butt. I am very very happy with this chair. Only feature I wish it had is if the arm rests slid forward and backward. Everything else about I love and most important it is comfortable for a long day of tasking! Give it a try you will not be disappointed

I'm just nearing the 1-month mark of owning this chair and I have to say that this is a pretty comfortable chair. What really attracted me to it were the number of adjustments it had as well as its discrete design. I am at my desk for pretty much all day up until late at night, going from working at home to gaming; so having something that allows to me sit comfortably was really important to me. This chair has satisfied all my needs but there are a couple of caveats that ought to be considered. 1) During the first couple weeks of using this chair, I found that the front pad that supports underneath your knee was actually too stiff to where it would actually be uncomfortable to sit after a few hours. Keep in mind that I'm 5'7" and even with my chair height properly adjusted, the pad was still too firm and uncomfortable. At first, I thought I was going to have to return it but I decided to give it a bit more time for it to "break in". By the third week, the pad finally "broke in" and now the chair is much more comfortable to sit in. If you are considering to get this chair, do keep this in mind as everyone has a different preferences and body types. 2) By pure preference, I opted to remove the armrests as I like to have my forearms resting on my desk. I found that the length of the armrests allowed me to only get so close to my desk that only my wrists could reach the edge of the desk. However, if you prefer to use the armrests, they are pretty comfort and provide good support. They have a rather soft padding and they don't cut off any circulation. While they do have a pivoting adjustment, I found that they were actually a bit too easy to move at times and there is no locking mechanism to keep them in place. Also, if you are like me and like to sit cross-legged, having the armrests installed still allowed me to do that with ease (again, it should be noted that I'm 5'7"). 3) The build process was pretty easy to follow and rather standard with most office chairs. As far as the build quality is concerned, it's really nice. For the price, you get a nice nylon mesh that supports the back and the seat. While most of the chair is made from plastic, there are metal components for the adjustment points that also add a nice color accent.

I've been working from home for almost 2 years now. I was WAY over due for chair upgrade. I went to Office Depot to get a new chair mat and started looking at chairs while I was there. When I sat in this one I got a nice warm fuzzy. I'm not a fan of gigantic overstuffed chairs (leather or other). Nor was I too happy with the stool with a back rest type chair that I'd been using. But then I looked at the price and immediately lost interest. Still, I took one of the extra description tickets out of the plastic pouch on my way out. When I got home I looked it up online. Turns out it was on sale at Office Depot, though it wasn't marked as such. Better, it turns out they were offering the chair here on Amazon at the sale price, one that wasn't making me choke. I read the reviews, looked at the specs, perused a few other options and decided to order it. UPS delivered it a few days later. As others have noted, it looked a little haphazardly packed in the box. Still, everything was there and nothing was damaged. Assembly was pretty easy, that stool w/a back rest chair made a great assembly platform. Everything worked as advertised and the chair is comfy. The controls are easy to use. I particularly like being able to adjust the seat depth and the height of the seat back. I'm able to position the two relative to each other such that my legs are well supported and the lumbar support section is just where it's useful. Once I cranked down on the tension knob for the reclining backrest the setup was perfect. Time will tell, so far I'm very satisfied.

Very Sturdy. Adjustable to fit all body styles. Total quality built. Super easy assembly with 7 screws (allen wrench included) and slide the wheels onto the base. Set the shock into the base and the chair onto the shock. 10mins assembly. I'm 6ft 260 and I have had this same chair at my desk 5 days a week since Nov 2019. Looks/feels new. The mesh bottom does not stretch, sag, mis-shapen. It actually looks and works like new. I added roller blade wheels when new because I'm on a concrete surface and the plastic wheels were noisy on hard surface. I have purchased this chair for 6 people of different sizes and body types and all of them can adjust the chair to have proper support.

I sit on some really nice chairs at work. Usually a Herman Miller Aeron or a Nightingale IC2. These chairs made it very apparent just how inadequate my home office chair was. Even though the typical 100 dollar chair is terrible, i still dont want to pay 800+ dollars for a chair. That's where the Quantum 9000 fits so nicely. It offers a lot of the comfort and customizability of the more expensive chairs for less than half of the price. I find it to be perfectly comfortable and provides enough settings to get it to feel just right. I am 6', 220lbs and this chair is comfortable to sit on for hours on end when working or gaming. It is not quite as good as some of the more expensive chairs in in that it lacks a head rest, lumbar support, and you can't tension the mesh, but for the price point, it is most certainly a 5 star chair. You are definitely going to make tradeoffs between a 300 dollar chair and a 1000 dollar chair. This chair minimizes the tradeoffs and offers excellent comfort. It is fairly new so, if the durability is less than stellar, i will provide an update. At this time, I say this is a definite purchase.

I can’t say enough about this chair. I own one for my office and also my home office. My husband’s back felt better after we switched his chair to this as well! Worth every penny.
