get tempur pedic with a water proof casing...you will either love it and not use anything ever again or you will hate it...do not get it if you can not get a waterproof cover! you will ruin it if you use the factory cover it will smell like mold after a few months...you need to keep the tempur dry and then it is pure heaven...
its a thermo sensitive elasto polymer it changes viscosity with temperature change, it turns almost liquid when warm...I have 3 one main one, one for between my legs and one reserve...
I will never use anything except tempur
