Mattress Forum

This forum has been extrememly helpful as I didn't realize how complicated it is purchasing a mattress.  Last week, my wife and I purchased the Pure Latex Bliss Beautiful mattress.  My wife prefers softer beds so we chose the Beautiful over the Nutrition.  I have noticed that the Beautiful we have seems much more cushier/softer (almost liked sleeping on a marshmallow) then the one we tried at the store.   I believe this may be that our bed has slats and does not require a box spring.  I was told we could purchase a bunky board or put plywood over the slats.  The other alternative would be to exchange the Beautiful for the Nutrition.

Do other PLB Beautiful owners feel like this mattress provides enough support?  Should I be concerned of the extreme softness of the bed? I think I am paranoid as I have read that you shouldn't purchase a mattress that is too soft as it may potentially cause spine misalignment.  Thanks in advance for taking your time to read this and providing your input!
