I have had this chair for a couple weeks. It was easy to assemble and is comfortable to sit in for long periods of time. Love the ability to raise and lower the arms.
I wanted to love it. I really did. It's super high quality in its parts (lots of sturdy metal in the arms and the base) and it went together fairly easily. But this chair just isn't adequate for lumbar support. I'd read a few reviews that said it was ergonomic and I'm short and one reviewer even said it worked for her petite frame but the issue isn't the placement of the lumbar support but the fact that it's not firm at all. In addition the chair naturally tips back a bit - it doesn't sit straight up even in the locked position. With the addition of extra lumbar support pillows and a neckroll I am comfortable enough. If we weren't mid-COVID precautions and I could have gone to the store I'd have returned this after a day.
I would give this chair 5 stars if it weren’t for the installation process. Talk about frustrating! Main concern is the manufacturer appeared to have put loctite on the bolts at the assembly plant. The issue with that however is that the loctite dried before even being ready to be used causing the bolts to be EXTREMELY difficult to install. My advice for the manufacturer is to include the loctite separately so the installer can use it properly.
