SIDIZ T50 Highly Adjustable Ergonomic Office Chair (TNB500LDA): Advanced Mechanism for Customization/Extreme Comfort, Ventilated Mesh Back, Lumbar Support, 3D Arms, Seat Slide/Slope (Blue)

PRO: Comfortable! Actually, very comfortable. Better than my desk chair back in my company office and my other home office chair.PRO: Adjustable! Love the adjustable recline depth and lumbar support. I'm 6' tall and the lumbar lines up perfectly at the highest setting (goes up and down) and for the first time I can say a lumbar support is actually helping my posture!PRO: Assembled in 10 minutes. It came in 6 pieces - base, seat, back, 2 armrests and height mechanism - with 6 bolts and practically assembled itself. The wheels were even pre attached to the base!PRO: STYLE. It looks GOOD, not your normal corporate-drone black style that I def didn't want in my living room. The white, gray and blue looks excellent.CON: Seat tilt doesn't lock in place. There's a lever to lift the back of the seat so it tilts you forward, but it just goes back down under my weight (240lbs). Not a problem for me at all though, at 6' I don't need any extra height.CON: Armrests don't come up quite as high as I'd like, but again I'm very tall so probably not a concern for most people.

I love almost everything about this chair. The seat height is perfect for me as am I only 5', it has many adjustable features, and the seat is comfortable. However, the back is way too hard due to the lumbar support bar, which cannot be removed. I almost returned it because of this but kept it due to to limited options for short people. I keep a blanket over the back for padding.

I'm so glad I purchased this beautiful chair. My previous desk chair was expensive enough that I thought it would hold up, but it didn't. This chair is very adjustable to your specific needs. Seat forward, back, back stable, loose enough to recline easily, heighth, even the arm rests are adjustable. The lumbar support is adjustable and very nice indeed.I can sit in it all day without pain and suffering, which is rather nice.I did add a set of roller blade casters for better mobility although the ones that came with the chair are absolutely gorgeous. We're saving them for my wife's chair. as she doesn't use it as much as I. The traditional rollers that came with my old chair scratched my vinyl floor and wrecked havoc with my oxygen tubing. The roller blades have solved that nicely.

I bought this chair to replace a 10+ year old sub $100 chair that was starting to fall apart. Since the COVID-19 pandemic I'm working from home full time and needed something that was customizable and supportive. I have lower back issues and currently have two bulging discs in my lower back. I had back surgery 25 years ago to repair a ruptured disc so support and comfort while sitting are a very high priority for me.First things first - let's talk about assembly. It couldn't be easier! There are 6 bolts you have to install - 2 for the arm rests and 4 for installing the back to the seat. That's it! It's unbelievably simple.It took me about 10 minutes to adjust the chair to my liking but that's because it's so customizable. I sat in it for a while, working on my laptop at my desk, and immediately noticed how much better it was coming from my old chair. I sat in my old chair and couldn't believe I sat that way for 10 years. It's a night and day comfort and support difference sitting in this chair.The Sidiz T50 chair is a bargain for what it offers and my only regret is that I didn't find and buy this chair sooner.

The chair is great in an ergonomic sense and assembly is quite easy. Shipping was on time and the chair was packaged very well. The only gripe I have is that when I recline and return to upright, there is an annoying spring sounding click in the mechanism below the chair. It is quite loud and pretty consistent. This is not the highest end chair but it's not low end either so I'm a bit disappointed.

I bought this a half year ago, and the seat fabric has ragged out already. So, I contacted the seller, SIDIZ USA to buy a new seat but no feedback from them. Also, the chair back moves a little, and can't be secured firmly although it's in locked. This is different from most of other chairs, so it can be annoying.

I spent a month looking for the right chair. When this finally came, I knew I made the right choice. It’s more comfortable than many Hermann Miller chairs I’ve used at the office, and immediately fixed my back problems developed while sitting on dining room chairs to work.By far the best value for money in the task chair department that I’ve seen. Of course I’d love the higher end Steelcase version, but for a home office this does the same thing just as well. I can’t speak to longevity, but in 6 months its held up extremely well and is just as supportive as the day I got it. The only downside is the lumbar support tends to shift on its own, so it’s less supportive right there than I might prefer.
