Early review and I will update if anything changes but so far this chair is awesome. I am 6'3" and weigh about 280lbs. I herniated two discs in my back at the same time (L4-L5 and L5-S1) and let me tell you this: It sucks. I would not recommend it to anyone. I immediately realized how bad my old chair was on my back, so I ordered a gamer chair with a hard lumbar pillow thinking "hey, this will work. It's designed for gamers. Gamers sit ALL THE TIME. I just need it for watching Hulu at night with my wife and playing games a few hours on off days." Nope. The chair wobbled and soon tilted and now is almost as bad as the chair I replaced. I saw this chair and after reading mostly positive but still somewhat mixed reviews I went for it. I'm glad I did.First let's talk Assembly.This chair is easy to assemble. Like, really easy. I have assembled many computer chairs and desks in my life. This chair is the easiest I have ever assembled. The instructions are clean and concise (Although let's be honest, you could probably figure out how to assemble a chair on your own) and each step has its own page, making it really easy to keep up with where you are in the process. Each step has a full size picture too. The design of the chair is brilliant in that when you put the arms on the base, they make cups for the back to sit in. Also, PRO TIP: AFTER YOU UNBOX EXERYTHING DON'T IMMEDIATELY THROW THE BOX AWAY. Close it back up and use the box as a table to assemble the chair. When the seat of the chair is on the box, it keeps it at a comfortable working height and allows enough room on each side to easily and quickly attach the arm rests. AND if you have a drill with the right size bit, use that for assembly set on medium torque. Saves time and ensures you don't over tighten if you are heavy handed like me.TOTAL ASSEMBLY TIME: <15 MINUTESNow, let's talk about Design.The Design is simple and straight forward. No "slope the back to 180 degrees and invert to form a gravity table. Then transform it into a picnic basket with wheels and go to the park with the jet engine attachment". It is just a chair, plain and simple. I like the way the arms are designed because it prevents the possibility of the chair to "sag" or "bend" with use as I see with a lot of chairs that have the L-Shaped support from base to back. The two-bolts-in-back-two-in-base on each side design has seen the most success for me in the long term. Hopefully this will hold true with this chair. The lumbar pad is firm and the adjustment knob is easy to use and fine tune to the exact pressure desired. Perfect for someone with back problems. The base is stable and the casters snap in firmly but easily. The chair raises and lowers easily and is insanely comfortable. PLEASE NOTE: This chair truly is designed for big and tall people. If you aren't big and tall, maybe look elsewhere because at the lowest setting, my feet JUST sit flat on the ground. If I were any shorter, my legs would be dangling. Of course, I guess you could just get a footrest, but either way take note.Now comfort.So far the chair is insanely comfortable. The extra padding at the front keeps my legs from falling asleep and the lumbar pillow not only prevents an extra onset of additional back pain but also seems to be alleviating some of the pain. I honestly cannot remember the last time I could sit down without feeling excruciating sciatic pain. Here's a Haiku telling you just how I feel.Happy tears streamingmy face, now a waterfallI blossom like springThe arm rests are a comfortable height. My head actually hits the head rest, though I usually don't have my head that far back. The width is comfortable and it feels stable and sturdy.OverallI am so far very pleased. As time goes on I will update if anything changes. Otherwise, As it stands now, you should definitely get this chair if you have back pain. Oh, I didn't even mention yet, THIS CHAIR IS SO AFFORDABLE! I almost projectile vomited all over my screen when I searched "Best office chairs for herniated disc". THOUSANDS OF DOLLARS! What?! for a chair?! But then Amazon had my back (HAHAHA GET IT?!) And I put down the hammer as my piggy bank's eyes went from terror and disbelief to relief and shock, still amazed that I could have ever thought to smash him to pieces for the delicious money inside. Seriously though, if you're still reading this then you obviously are really interested in the chair. Just get this chair.
