These layers are classified into two categories:

Comfort layers:
The comfort layers are usually between 2 and 4 inches thick, contributing to provide sleepers with comfort, support and temperature regulation, etc. The mattress may have one or more comfort layers for various purposes, therefore, if the comfort layers are too thin, the sleeper may not get the proper comfort and support, or cooling night’s sleep they want. 

Base layer (foundation layer):
The base or foundation layer of a mattress is responsible for its durability, breathability and support. In general, a quality mattress should be equipped with at least 50 percent of base layer. And for optimal support for heavy sleepers, the base layer should be 6 inches thick or more to prevent being worn out soon or sinking and sagging in the mattress. 

All in all, the importance of mattress thickness can not be ignored when picking your comfy and quality mattress. A thicker mattress may make getting in and out of a bed difficult, but a thinner mattress may not be supportive and soft enough for most grown sleepers. But when it comes to 8- to 14-inch thick mattresses, you are more likely to shop for a perfect mattress, which gets the balance between comfort and support.
