Just outside Nashville...
Had a mattress topper of Memory foam. Made my back hurt terribly................
Made in USA by the Chinese...
I have a Serta 2-1 pillow with 1/3rd memory foam and the other side poly fill.
I took out the memory form and added a pillow protector and a pillow case and the memory form is just the right height for me. I have tried others but they are always too thick.
May be the same but different color foam
