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? =)
Review: Most comfortable chair I've owned, great Hermon Miller Aeron alternative - After buying three chairs for $250 or less I realize I needed to spend some money for all-day comfort. I was sold on the Herman Miller Aeron, but it was easily crossing a thousand dollars with the add-on options I wanted. I did some solid research on Aeron alternatives and I selected this one based on price (excellent), reviews, how it looks, and the ability to return it if I didn't like it. The chair was easy to set up, super comfy, and at first, my body was like, "this is different, it's a new chair, do you like it?" Within an hour I had stopped thinking about the chair and just worked the rest of that Friday. The following Monday I played around with all the adjustments and got it dialed in. It adjusts in so many ways, you can easily set it up to your needs. In the days after that, I never thought about the chair again. I can work all day in the most comfort I've ever had in a chair. For me, the adjustability and comfort alone are worth it. It happens to be affordable and looks great too. #### Here's my take after 1.5 weeks and 40 hours of sitting: Pros: The back tension is amazing. I leave it unlocked so I can lean back as far as I want and yet sit upright without locking the chair. I can easily rotate the handle to adjust the tension while sitting. When I want to lean way back, I turn it one rotation looser. ... The seat chair is plenty "long" and you can move it forward and back. I can sit with one leg Indian style and this is helpful. The seat cushion is just right. Soft enough to stay comfortable all day, thin enough so it feels appropriate for an office chair. The armrests are super cozy and go up/down and rotate inward/outward. It's easy to assemble. It's very stable. Feels great. Cons: It sits high, even in the lowest setting. I'm 5'10'' with slightly shorter than normal legs. But I didn't have any problems. Usually, chairs go lower. The forward seat tilt feature is an on/off thing. You cannot choose how much forward tilt you want. You can just turn it on. With that said, forward tilt felt great, but normal felt even better. So I keep it off. The headrest is useless. I find this true in all headrest chairs. The lumbar thing is cool, but I just tried to make it as if it didn't exist. I'm not a fan of these. I was able to get to where I don't notice it is there. ##### In conclusion, I did a lot of research, purchased three other chairs in the last four months, and this one is leaps and bounds better than those $200 - $250 chairs. I highly recommend it. This is the most comfortable chair I've ever owned.

## 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.

### ⭐⭐⭐⭐ Plenty of features for the price with few flaws
*by S***E on December 15, 2023*

This is a great ergonomic office chair for the price considering it has many of the same features and adjustments as the Steelcase and Herman Miller chairs that cost 2-4x more. I came from a refurbished 10-year old Steelcase Leap V2 and found the Sidiz to be the better purchase for the money, but with two minor exceptions being the lumbar support and headrest. First, the way the lumbar is adjusted is intuitive, but it does not stay at the angle you set it to if you push on it too hard with your back. Isn’t that a little ironic as a support? If there was a way to lock it down, this wouldn’t be a problem. The lumbar support cushion itself could also be improved as it’s a little hard on my back. Luckily you can reduce the amount the lumbar support protrudes into your back to almost nothing so if you are concerned about it being uncomfortable, know it is essentially an optional feature. The other issue is the headrest. While it’s an amazing feature to include at this price point, it only works well in one position and that’s when your head is, well, resting on it and pushing it all the way backwards. You’re supposed to be able to adjust its angle forwards, almost to the point where it is pointing downwards towards the seat cushion (not that you would want this, but it has plenty of adjustment range) but the headrest doesn’t stay in the position you set it to as soon as you press your head into it, almost as if there is a loose screw somewhere. You can try to tighten it down more but I wasn’t able to. The headrest still functions just fine when pushed all the way back, but I only find it useful when I’m reclined and relaxing, not when sitting upright. Oh, and the complaints I’ve seen on other websites regarding the cushion being too thin and bottoming out after an hour of sitting are inconsistent with my own experience. Sidiz appears to have revised the cushion so it is thicker since those comments were made and I find it more comfortable than the Leap V2 I had as well as some of the mesh types from Herman Miller. Overall, I’d purchase this chair again if I needed a second one.
