Hey guys, any recommendations for where I can get a decent mattress? I really can't spend more than $500 or so, and I need for it to last for at least 5 or 6 years if not longer. The idea of a used mattress really icks me out, so I need a good deal on something new. I'm looking at some faux-Tempurpedic stuff on Overstock, but I'm not sure I can go through with buying a mattress online without laying on it first. Any suggestions?
