This year I purchased bulk latex foam noodles ("LaNoodles") from CozyPure, plus two high-quality cotton zippered pillowcases with wool batting from another store.

I was already a believer in Talalay latex as a mattress material, which is what my current bed is made of.

I stuffed two queen-sized pillows to almost bursting with the LaNoodles. One I place in between my thighs, and the other is my normal head pillow. They are ridiculously thick but I no longer have knee pain or neck pain and sleep much better.
