This chair is great - looks amazing, so comfortable, love the options, love that the arms rotate up, great back support. BUT. Every time I move it sounds like the chair is about to snap in half. I called Wayfair and they sent a replacement, and the new one was better for like... an hour. Now it's even worse than the original. It's almost as if the bolts keeps coming loose. I recognize the sound from when it was being put together. So I don't know if the secret is to tighten the bolts every few hours? I'm wildly disappointed, as I spent so much time looking for the perfect chair. This one is SO close, if I just hold perfectly still for the entire day.
