The quality of these seat cushions is great. I really love the color of them, it is more of a charcoal than black though. The reason that I gave them 4 stars instead of 5 is because I thought that there would be more filling in the cushions. They are still quite comfortable though. I just put them on today, so I guess we’ll have to wait and see if they get flat fast or not. Hopefully they will last a long time.
