The chair is comfortable and BIG! However, the wheels are already breaking off.  I haven't had the chair for long (a few months), it is on a large plastic mat for easy rolling, and some of the wheels have already broken off of the metal post.  If I am not mistaken the problem is related to the part of the wheel that connects to the metal post being plastic.  That part has bent out and now the hole is too large for the post to stay connected to.

We purchased the chair in May 2024, it is January 2025, there is no support offered as it is outside of the 30 day window, no warranty either.  TERRIBLE PURCHASE
