Review: Outstanding chair, terrible desertcart home service support - 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 desertcart home service. I originally purchased desertcart'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 desertcart 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 desertcart home service assembly. You can just as easily assemble it yourself for much less hassle.
Review: It lives up to the hype! *UPDATED REVIEW* - 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 desertcart 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? =)

## Questions & Answers

**Q: If the seat height is set at 17.5", how many inches from the seat to the middle of the head rest? Typically, head rests way too high for short people.**
A: I am 5' 3" and the bottom of the headrest starts at the base of my neck and covers the full back of my head. It adjusts forward and backward which is very handy. When I work I usually pull it way forward so that I look straight forward but can lean back on it which relaxes my neck. When I do a full recline I usually push the headrest back a bit.

**Q: Can I buy a replacement seat cushion?**
A: As for the customer service including a replacement request or so, we can help you. Please contact us at customer@sidiz.com.

**Q: I'd like to use my own casters. What is the caster stem size for this chair?**
A: Please refer to the dimensions of the casters below. 

- Diameter of the wheel: 2 inches
- Diameter of the stem: 0.4 inches
- Height of the stem: 0.9 inches

**Q: Does this chair have a big and tall model?**
A: No.

### ⭐⭐⭐⭐ Good for the price
*by C***S on September 6, 2020*

I've owned this for just a month and I'm 5'11/190lb, so keep that in mind. After breaking two cheap (below $100) chairs and returning another two (a $150 and a $200), this looks like a good compromise between getting a good ergonomic chair to work from home but, without breaking the bank, since a Herman Miller or Steelcase both are over $ 1000 new, and I didn't want to roll the dice with a used ("refurbished") one so this seemed like a good alternative since it's backed up with the Amazon's return policy. The good: - It has very, very good adjustability. - The design is very attractive. - The cushion/cover can be removed for washing. - Materials are of good quality (not top-notch but definitely you can tell the difference against the cheaper chairs). - The base above the gas cylinder is aluminum. - Rolls very smoothly (I've used mostly on a hard floor tho) The room for improvement: - Not the best cushion, not bad either but yeah, could be better. I have to switch positions from time to time so my buttom doesn't get numb (not that often that bothers me, also I used to switch and move a lot even with Steelcase chairs back at work). - For particular situations, the headrest is somewhat useless. It will not stay in place if you lean back (all the way) and.. try to rest your head there, it starts to move back until you end up in a very uncomfortable position. It should have a locking mechanism. It's ok if you just want to rest your head from time to time when you are in a sitting position. - It started squeaking already, some noise is understandable, but there was one driving me crazy, especially at night when it's all quiet. The mechanism for tilting the seat is all plastic parts, so when I moved (myself, not the mechanism) I could hear it squeaking, I wasn't even leaning, just the movement over the seat alone, like side to side would trigger it. I ended up disassembling the chair to put some silicone grease in all moving parts, that did the trick. Mainly this is why I put 4 stars. - Speaking about the devil, that seat tilting mechanism could be the weak point for its demise, even though the base is aluminum, in the end, your weight will be supported by those plastic parts. In their defense, there IS a metal bar connecting all those parts, but still. I'll try to update in a few months since I'll be keeping this. All and all, I do like this chair, especially for the price point and what it offers in return. [Second-month update]: Wheels started to squeak as well, I applied the same silicone grease between the metal inserts and the hole, that fixed it. [Tenth-month update]: The seat foam gave up. I was getting numbness on my buttom after a few mins. Contacted support, they sent a thicker replacement foam. So all good, I'd still recommend this chair.
