Where is a good place to get a deal on a mattress?
I have bought expensive mattresses, cheap mattresses, and everything in between. Within 3 to 6 months, they all turn into bowls, sagging in the middle. I am tired of sleeping in a bowl, and want to go mattress shopping, but I don't even know where to start. I have tried local furniture stores, chain furniture stores, going out of business dumps...any advice?
