The chair had good instructions and was easy to assemble. I do wish it had a seat depth adjustment of more than 1/2 inch and I wish I could lock the back in more than the two positions offered. It does roll nicely and is pretty comfortable.
I went through 4 chairs. I work from home all all those chairs would make back and bottom hurt so much I’ve have to have aspirin daily. I sit from 12-15 hours a day so I chucked it up to it being just long hours. But this chair I sit in all day and NO PAIN!!! Anywhere!!!!!! It is heaven sent and worth every penny!!!!!
