So I love the color, and it’s soo comfortable. However, (1) It did not come with instructions. I had to call and have them emailed to me before I could do anything. (2) Nothing was marked as the instructions were labeled. (3) Not sure if it is supposed to be this way. I wouldn’t think it should be, but there is a small gap where the base and the back of the seat meet. Yes I tightened all of the screws I even completely took them out and re put them on twice I even had my husband push the back and bottom together as much as possible before I tried to screw them together again.
