You could well have found that the latex mattresses are a bit thicker than the innerspring mattresses norm. You will be delighted to hear that except for mattresses that have innerspring, natural latex mattresses have a lot of elasticity (thanks to the central rubber) and prefer to retain their form in sensitive places for years despite rotting or buckling. There really is no reason to regularly turn them over to prevent the latex from sags, bumps, lumps.
