The chair is very comfortable if you are sitting for long periods of time the only down side is the only way to adjust the seat it to have the back of the chair tipped back.
The seat cushion is nice but I find it slopes towards the floor too much for my taste. The chair was easy to assemble though the directions could be a little more descriptive. The rollers seem to stick a bit but I do have a lot of dog hair in the house. Overall it’s about what you’d expect for the price.
Although the website says that the black and blue are the same they are not - the blue has a very nicely padded fabric seat while the black option is a mess seat. I ordered the black at first and realized the difference while assembling. These are very quick to assemble and very comfortable.
