One of my only complaints is that the instructions weren't too easy to follow, but it's pretty simple to figure out on your own. It might even be a good idea to replace the nuts with some better ones you might have lying around cause the ones they give you tend to come loose. There are probably more comfortable seats out there, but for the price, it's been worth it for me. Despite that, I use it very often at work, and it's been pretty solid. It's also fine at taking welding sparks, but those sparks will burn holes into the seat as sparks tend to do. I'll give it a generous 4 stars because of the affordability.
