It’s only been two days since I received this chair, but it’s already a major improvement from the cheap one that I had. My back hurts WAY less than it did. I love the lumbar feature, and love that the arms go up and down. Also, the padding on the seat is a major upgrade. After 8 hours working from home, it can be a little uncomfortable but I’m making sure to get up and move more often to remedy that issue. The only complaint is that like most instructions, it’s just pictures with no real “instruction.” It went together pretty easily, but I cannot for the life of me figure out how to make the tilt feature work. That’s why I gave this four stars instead of five. Overall, a really great chair for my home office!
