SIDIZ T50 Ergonomic Office Chair : High Performance Home Office Chair with Adjustable Headrest, Lumbar Support, 3D Armrest, Seat Depth, Mesh Back Computer Chair, Alternative Gaming Chair (Black)

This is by far the best chair I have purchased. I am 5'4 and the seat depth on the shortest setting is perfect. The lower lumbar support is also at a good height at the highest setting, but if my torso was taller, the lumbar support would be too low, so I would caution a taller person in buying this chair that needs sufficient back support. The headrest is at a comfortable position, although it is on the higher side so when it is moved forward to help what is advertised as fixing "text neck", it does not fall into the right spot and is rather uncomfortable. The seat is extremely comfortable and good for at-home work where I sit for the majority of the working day. The only complaint that I have, which is not related to the capabilities of the chair, is the support from Amazon home service. I originally purchased Amazon's service team to come assemble the chair for me because it looked like a quite complex setup with all the adjustments. After waiting at home during the four-hour time slot allocated for assembly, the tech never arrived. I tried to contact Amazon support and could not get through to a real person, and the only options were to check shipping, reschedule, or cancel. I finally sent a message to the seller and told them the tech never arrived. I got a response 15 minutes later that said they would contact my local repreatatives. An hour later after hearing no response, I contacted them again and asked if any progress had been made. They said I could reschedule for a later date. I ended up cancelling the Home Service Support and assembled the chair myself, which took less than 10 minutes. The chair is 7 peices with a 6 screw assembly and comes with a heavy-duty Allen key to screw everything together. They even ship the chair in a box that is the perfect size to rest the bottom of the chair on in order to attach the back. All of the ergonomic adjustments are shipped pre-installed so they cannot be messed up during assembly. The only semi-difficult task was to flip the chair upright once assembled because it is such a sturdy chair and is a little heavier than it looks. I have assembled furniture from places like IKEA and Wayfair (including office chairs) and this is by far the easiest assembly I have completed. If you are to purchase this chair, I would strongly discourage you to purchase the $60 Amazon home service assembly. You can just as easily assemble it yourself for much less hassle.

UPDATE 6/5/2020 I was so happy with this chair that I immediately gave it 5 stars and all the accolades that it deserves. Well, a few days into using the chair, I noticed that the seat cushion was defective. It was defective in a way that the foam gave out way too soon. I am 6' tall, 195lbs, and I don't think I weigh enough to wear out a seat cushion that quickly. So, I reached out to Sidiz and they were very helpful with my concern. They took time to figure out what could be wrong with the product that I received and sent me a replacement cushion. I received the replacement cushion just an hour ago. I inspected it and compared it to the original seat. They sent me a seat that's about an inch or so thicker. I also noticed that they used a different foam material. Or maybe it's just the color. Anyway, I installed the new seat and I have to say that it is so much better! Yes, it is much more firm than the original seat, but there is enough give to it that my butt settles into it quite nicely. I also experience pain on my coccyx due to a snowboarding accident years ago, and I don't have that problem with the new seat. This is the first time I experienced that an Amazon vendor has given this much attention to a customer's concern on their product. And for that, I give them 5 stars! As for the squeaking sound you hear, it's coming from the lumbar support section. It's a sound produced when 2 plastic parts exert pressure against each other. I imagine that this can be alleviated by adding a thin layer of padding. Unfortunately, there is no way to access the screws on the lumbar support unless you peel away the mesh back. The sound only comes out if you're moving too much on your chair. If you are very restless, then, you'll hear more of that sound. It doesn't bother me at all because I sit pretty steady. So, that's that. I am a happy camper! I recommend this product, not only because it's a good one, but because the company has a very good customer service! _______________________________________ ORIGINAL REVIEW: I just got this chair delivered minutes ago and I was so excited and assembled it immediately. It took less than 10 minutes! Lay down the feet, put the spring, attach the back onto the seat. Attach the arm rests. Position the chair onto the spring. Voila! All of the chairs that I have bought, returned, or given away, have all been short in height. I was skeptical about this one. But the fact that it has a seat height adjustment on top of the spring mechanism, is amazing. I am actually seated perfectly now, with both feet flat on the floor with my knees bent at 90 degrees! The other amazing thing about this chair is that it comes with adjustable armrest height. This enables me to position my arms properly, and straight reach to the keyboard and mouse. Again, that angle is critical and I am definitely glad that this chair allows me to have that. The adjustable lumbar support is also a welcome change. Gaming chairs just give you that pad, which does nothing, really. With the T50, the lumbar support can be adjusted to what your body needs! I did wish that the horizontal adjustment added another inch. Even the headrest is adjustable! They really thought of everything! One thing I wished it included was a selectable tilt angle/height. There is just normal and the high level. Nothing in between. Well, almost. They didn't add a leg rest. Then again, if they did, I'd be sleeping on this chair! And we don't want that now, do we? =)

Excellent quality and a well thought out design. Made in Korea...not China

Love their customer service, quality and design of the chair. No regrets, this is definitely one of the best purchase I’ve ever done.

Initially, this chair seemed like a good buy, but the seat padding has proven to be of poor quality. After only six months of use, it's practically as if you're sitting on the hard plastic below, offering little to no comfort or support. Dealing with the supplier for a resolution has been frustrating. They've asked me to jump through numerous hoops, demanding multiple photos and insisting on direct contact rather than handling it through Amazon's platform, which is inconvenient and time-consuming. Overall, I do not recommend this chair. The comfort level drops significantly after a short period, and customer service has been less than satisfactory. Look for a better quality option for your seating needs.

This chair is alright, once I added in a footstool and some arm rest pads. As it is the chair lacks the range of adjustments found in other chairs like the ones in my WeWork office. The arm rests don’t go high enough and the chair itself doesn’t go low enough. Wish I hadn’t bought it but not sufficiently displeased to return it :)
