I hate that the arms going into the holes of the chair (picture taken for your review) are not professionally done - as you see the holes look like a cardboard box hole. For $100 even though it isn’t a $5,000 executive chair, it isn’t $19 either. This part should be better quality. The overall comfort is exceptional - I like the locking mechanism to assist with keeping my back straight when working at my desk, and I like that I may unlock to lean back and rock myself. I am a very busty 5’5” at clothes size XL / 208 pounds and LOVE how there is ample room on the seat for my tush! One of my dark black tops bled onto the back of the seat; I freaked out but was able to use mild clear soap and warm water on a rag not heavily saturated to wash off the black - it came off THANK GOD! So now I keep a furry throw on the back of the seat to avoid that ever again. It was really easy to clean! Overall I recommend this chair; I work 7 hours per weekday on it and it’s been a great chair for this purpose throughout the current pandemic since I purchased late Fall last year.
