I took a chance buying 4 of these chair cushions because they were a return item and not refundable.  I really expected there would be some type of problem with them.  Boy was I wrong!  They are beautiful, thick, and do not go flat after much use, and they are an exact fit for my chairs.  I am using them on my patio table and chairs set and they get a lot of use.  I am quite happy I took the chance and got exactly what I wanted at half the price.
