Attached is a breakdown of the BeautyRest line of mattresses. The pdfs show the foam densities, thicknesses and arrangement of BeautyRest mattresses Foam. Hope this helps people make an informed decision.
Hi gulfsurfing.
Welcome to our Mattress Forum! 
Thanks for providing the pdfs with information about the materials and components inside the BeautyRest line of mattresses. I appreciate it.
The breakdown of the materials with densities you provided will surely help consumers make informed choices and meaningful comparisons between mattresses and assess the quality of the materials and components against the durability guidelines here to make sure there are no lower quality materials or weak links within the mattress they are considering that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.
