Very sturdy and well worth the price!
Color: Black
First, my chair arrived faster than I expected! It was delivered in a well packed box and everything was plainly marked! It assembled very easily as per the instructions. The only thing I would recommend is to have another person available to assist with the installation of the back rest onto the chair. It gets kind of cumbersome for one person, although I did it myself… another tip start all screws before tightening, especially with the arms and the back rest cushion!
It only took me about 25–30 minutes to do the whole thing by myself..
The materials are of good quality, very sturdy and I really like the dual casters as they glide on the floor really nice!
Well, worth the price!!!

My best office chair!
Color: Black
I haven't really given a lot of reviews before. But that said I weighed 260 at 6 ft 3 in. I have to admit this is a pretty comfortable chair! It was easy to put together, and my legs don't go to sleep anymore sitting in an office chair The lumbar support is really good. I'm just glad I was able to find this chair, and about my son another one and it'll be here Friday! You can't go wrong with this chair! I love it so far!

while big and wide seat....
Color: Black
while big and wide seat is nice this chair has just seemed off since i got it, it seems like it only reclines part way and it feels like it is leaning forward in normal sitting position and one of the wheels fell off the mini ball bearings fell out of the swivel part of the wheel and left the wheel unstable only to fall off. while the actual seat of this chair is big and wide (not so comfy) the mount seems off and cant recline all the way back like in old chairs, the wheel thing suck but i can replace a wheel could have been much higher quality for what i paid for the chair.
UPDATE: over the past few weeks customer service reached out to me about the chair and fully addressed all of my concerns, to my surprise they offered to replace the chair at no cost to me. The new chair is much better than the old one everything seems good to go and i got upgraded wheels that dont have that same type of ball bearing, so i dont think these wheels will be an issue. Thanks to the customer support member Luka that reached out to me and made everything correct.

Nice Chair but it does not work for long.
Color: Black
This is a very good chair when you buy it. Comfortable and fits bigger people well. The issue is that you only get to enjoy it for one year. After one year of very light use the main seat piston that adjusts high has already failed leaving my chair stuck at the lowest height. I could not imagine how fast it would have failed if I used it a lot. I did not even sit in this chair more than 3 days a week for 2 hrs. I am nowhere near the weight limit for the chair. It just does not last.
