Ergonomic Office Chair - Adjustable Backrest & Lumbar Support, Large Mesh Computer Chair with Tilt & Lock Function

Got this for my husband since he started working from home and needed a chair more comfy than his previous ones. As soon as he sat on it, I could tell that it was love at first SIT. HAHA! He swiveled and rocked several times with his eyes only half closed because he was in the zone. I sat on it too, cool stuff. Well made, sturdy and easy to assemble. These are his exact words below which I just copied and pasted..lol. “ Very ComfortableIf working from home is the goal, then this is a very good choice for seating.It was fairly easy to set up with straightforward instructions.Its base is roomy enough and the reclining function is very smooth and relaxing.Two things I wish were better are the neck rest which isn’t customizable enough, especially seeing its lowest position is quite high for my neck, but also the chair doesn’t go up really high. So its quite close to the ground.All in all, I am happy with the chair and recommend it”

Context: I practically live in my office chair (WFH, online school, some gaming) and I'm 6'1" / 250 lbs, so I put chairs through their paces.BLUF: It fits the bill for an inexpensive, ergonomic mesh chair that fits me height and width wise. Some design issues come with this low price.Edit: upped to 5 stars after learning the chair can be fine-tuned to prevent the seat height from slipping.Comfort: Right where it should be for a place I sit while working, not so stiff that I wouldn't spend a weekend gaming in it.Ergo: My back is much happier at the end of the day.Seat height: Good for "big and tall", my 90-degree-at-the-knees height is roughly in the middle of the range of travel, so should be good for taller people too.Seat travel: Jams up sometimes, but it works. (This is my first chair with this feature)Back height: Nice that it's adjustable, but the mechanism pops out of place too easily (and quite loudly), should be redesigned to lock solidly in place after adjusting.EDIT: There are 2 small pegs along the track of this mechanism, turns out they are screws (phillips) and can be adjusted. No slips since I did this.Lumbar: Base setting is a little strong, and also pops out of place if increased.Neck rest: still a bit short and doesn't come forward enough, but a nice idea (these never work for me anyway so I had low expectations)Arm Rests: They're there and they work. Maybe a little narrow for a B&T chair.I feel like the chair is worth the price as is, but could go from OK to amazing by fixing the issues with the back and lumbar adjustability.

I'D LIKE TO KNOW WHY NEITHER AMAZON, or the SELLER, or the party responsible for MAKING thischair, riddled with issues that haven't been addressed contacted me to discuss my issues or my plead for resolution. I don't think you want buyers like me, who have long term mutual positive relations with you AMAZON, writing reviews like these without getting involved. If this company had updated their valve assembly, please make them send me (and maybe all the other buyers who repeatedly complained about this very risky issue) the updated version! If they haven't resolved the issue, I believe you will be getting many more complaints like mine. I haven't asked you to take the chair back, just make them resolve this issue!!!I went from a 4 star rating to a 1 star since the chair was delivered on 02/17/2023. See reasons below:(1 Star) Update 3: My continued aggravation causes me to drop my score all the way down to (1) star! Between the gas cylinder leaking at least once daily and the back rest and headrest slippage ongoing, if given the chance I'd return this chair in a heartbeat! Maybe someone my size (6'5" and 235lbs.) is just too big for this chair. Whatever the case I'd think twice about purchasing this chair!(2 Stars) Update 2: My aggravation causes me to lower my score even more! The gas valve issue is a daily thing and the back slippage reared its ugly head again. Unless this manufacturer corrects thes problems stay away. Not worth the money!Update: The chair is one month old and the gas cylinder that allows you to raise or lower the seat position is leaking. This means when I get up and then come back to the chair its height position seems to slip all the way down to the bottom. This is more a nuisance to me than a deal breaker, but it is clearly another issue this company needs to address!Original: I should have read the product reviews prior to purchasing this Chair. However, I was lured in by the $100 discount.The Pros:The chair is built with tall people in mind. I am 6'5" tall and always have trouble finding a chair with a headrest that can adequately provide comfort. This chair does that!The chair is extremely easy to assemble. The necessary Allen wrench and Philips screwdriver is provided.The seat area itself appears to be quite comfortable regardless of the lack of padding.The Cons:Although the chair has an adjustable back with lumbar support, and it can be positioned to accommodate your individual needs, IT DOES NOT STAY IN ITS ADJUSTED POSITION! It seems to slip out of position when you move or always when you stand up. It's a shame because it would be worthy of a higher rating if not for the adjustable back assembly slippage!
