Query: Good If you need something to last only a Week

A longtime ago I learned that you get what you pay for, and this product quality is one of those type of lessons I will have learned (again). Its firm for only about a week or two, I am a bigger person so that might have something to do with it to however, I highly doubt it. The foam is not firm at all, I would equate it to foam you might find a car panel which is not very thick or firm. You could literally set a cup of water on this thing and I bet it would sink flat, so unless you weight under 100 pounds this isn't going to work for long.I would suggest getting something that is going to last longer (i.e. memory foam), because if you are like me and injured your tailbone, you have a long year ahead of you...
