Abstract
A foam mattress with an adjustable firmness by inserting or removing filling bodies into openings on at least one side thereof is disclosed. The adjustment of the firmness may be performed by an owner/user of the mattress. The ridged patterns may form openings that enable the insertion and or removal of filling bodies that provide further adjustments to the firmness (or softness) of the mattress in addition to the other factors discussed above. The mattress may also be partitioned to allow the firmness on a first portion of the mattress to be adjusted independently of the firmness of a second portion of the mattress, and vice versa.
