WorkPro(R) Quantum 9000, Silla ergonómica, color negro, para la espalda media.

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.

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.

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

I went to an office supply store and saw this chair on sale for 20% off its retail price, so I sat in it, adjusted it to fit me, and about 15 minutes later, I realized I was still siting in it because it was so comfortable. I thought I should check Amazon to see what it was going for there and it was $230 less than the retail price, or 45% off! So I ordered it on Amazon. I was concerned that maybe it would be a refurbished chair (especially after reading some reviews of this chair arriving with damage), but when I got it just a day and a half later, it was is perfect condition, well-packaged, with good instructions and everything in the box needed to assemble it. The UPS delivery guy carried the box into my house, which was nice, since it weighed over fifty pounds. I took it up to my …

I had an office chair I'd been used for years. It was an inexpensive swivel chair I got at IKEA. It was OK but not designed for all day use. When I started my new job, I began to spend around 10+ hours in my home office. Back and shoulder pain ensued.Saw this chair at a store and it seemed like it was solid construction and comfortable. Weeks later saw the same chair on Amazon so I purchased.It was fairly simple to assemble. The only difficulty is needing a way to place the seat upside down on an elevated surface to attach the arms and back. Not too big of an issue since I had a barstool with a cushion and used that. If I didn't have that, it would have been much more difficult to assemble. The seat, arms, and back are heavy so it has to be something rather sturdy to set it on for …

**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 …

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 …

I just got this chair yesterday. I knew I made a good decision when I took out the allen wrench that comes with it and the wrench is about seven inches long. I mean, you can get some real leverage with that and they didn't go cheap with a short wrench like many manufacturers! The wrench and the few bolts you need to use come in a cardboard/plastic board that is well-marked with images, words and numbers. And they give you a spare for each type of bolt used. They also give you good very easy directions to put the chair together with special clear "warnings" for one step where it would be easy to do the wrong thing. The points to note are (i) it's heavy! I knew that from the box that was delivered - that's good! Lot's of metal and solid plastic, (ii) super easy to put together - less than …
