Oh Chris, we have 2 types of mattresses - you could simply have asked for a soft one. And although at $110 they were not the most expensive, they're 6 and 7 inches thick and not cheap either. I sleep on one of them (a firm one) and find it quite comfortable. You know, many problems can be solved if you let somebody know that you have them - there is no need to suffer quietly.
And for everybody else: read the references on our website - except for Mr. Prisco (who surprisingly never once complained while staying), most people like it here.
So go check out http://casa.carlita.20m.com and find out for yourself.
