The chair was very easy to assemble.  Took about 45 minutes.  The seat is very comfortable and easy to adjust the height.  I am on ceramic tiles and it glides with such ease.  When shopping for a chair, I was looking for a mesh back for easy air flow, as I get very hot in leather or pleather chairs.  Having e option to lift the arms completely out of the way is a nice feature as I share the chair with my husband and it’s a quick adjustment as he likes the arms down and I prefer them up.  Overall, very very satisfied with this product.
