If by "firm support" Sarah Peyton means ROCK HARD then the product description is right on. If, however, you prefer not to sleep on the equivalent of the Mojave Desert floor then this mattress is not for you. I ordered this product for my 12-year old daughter and followed the instructions re: airing it out and letting it inflate. That was over a month ago and the poor child has not had a good night's sleep since. Since I cannot fathom any way of returning the mattress I am now stuck spending more money on a memory foam topper for the brand new memory foam mattress. Oh, and the pillows are only slightly better than sleeping on a folded facial tissue. We are using them for decoration only.
