Mainstays office chair

This is a nice office chair. Easy to assemble and great sale price. The armrests go up so it fits under the desk nicely and it adjusts up and down with no issues. The only tiny little thing is the seat cushion is a little scratchy. I put a pillowcase on the seat cushion to solve that issue. This could just be me, read other reviews to see if anyone else mentions this. Besides that, it's great and I love Mainstays! They make affordable, great quality, house items.

Worth the cost

Very comfortable chair for the cost. I was a bit worried that the cushion would not be thick. While I wish it where thicker it is not bad at all. The lumbar support helps for me its just right. I will buy a cushion only because I have medical issues and need the additional support no matter they type of chair I have.

Comfortable and Easy to Set Up

This chair is really comfortable for WFH and feels good to sit in throughout the day. It was easy to put together too. I watched a video to help with the setup. It doesn't feel bulky, but it still feels sturdy and well made. I also like that you can easily adjust the seat height up or down. So far, it seems durable and like it will last a long time. Overall, I'm happy with it and would recommend it if you're looking for a everyday office chair.
