Are those foam memory pillows any good for neck pain or does latex provide better support?

I have a foam pilow that is pretty darn supportie- it has a formed shape that has a ridge that supports your neck. I find that the no-shape ones don't help much though. Sorry if this is hard to understand!Are those foam memory pillows any good for neck pain or does latex provide better support?
I have used the memory foam pillows. At first they seem nice but after sleeping on them for a few hours they get very flat and very hot so you wake up and turn them around. I don't like them for those two reasons. I like the shape for comfort. If you can find the right one: not too large and not too small in a regualr pillow type that would be the best. As it was I went back to a regular pillow but I just bought a more expensive one and have been sleeping much better since.


Hope this helps.
