Help, after doing allot of research, we spent a small fortune to relace our old sagging mattress and broken boxsprings. Now, personally, I LOVE the new mattress, but most of the latex benefits were for him. He is a pretty big guy (6'4" almost 300 lbs) , a very hot sleeper, terrible allergies and shoulder problems. Anyway, he is complaining about leg pain in his thighs when he is on his stomach. Does he just need to get used to the bed? We got the med firm version. Should we get a soft topper of some sort?
