Hey Nate,
Ive slept on those tempur-pedic memory foam beds and while they are soft and comfy, they are HOT!!! you sink down so far in them, they get REALLY hot! I couldn't get a good night sleep in it because of this! It was pretty cool that you could throw a big wad of keys down and lay on top of them and never feel them! Just a for warning! Try finding a hotel that has them and spend the night in it before you drop $600 for sample pieces from your friends! HAHA ( I think a king is $2000 for the mattress)
