Thanks for your educational site, even if it has made choosing the right mattress harder! I’ve been trying out different styles and the Berkley Ergonomics all latex 7 zone mattress is one of the ones I have liked. However, the way the mattress is designed with the zones being created by putting grooves of various sizes at the interface between 2 3"layers of the latex support core, the mattress definitely can’t be can’t be rotated. After reading about 2 sided mattresses lasting longer and rotating the mattresses, especially in the beginning, is that a significant concern? Would we need to take the thing apart and flip individual components?
