DETAILED DESCRIPTION

The present disclosure will be further described below in detail with reference to the accompanying drawings and embodiments. However, it should be clear that the specific embodiments described herein are used only to explain the present invention, and are not intended to limit the scope of the invention.

Referring to FIG. 1, a schematic diagram of a regimen mattress of the present invention is shown. The regimen mattress 1 includes the memory foam 2, the high density (HD) foam 3 below the memory foam 2, and the cover 4 covering the memory foam 2 and the HD foam 3 together to form the entire mattress 1. The HD foam 3 contains functional additive. The functional additive is any matter that can alleviate the symptoms of lifestyle diseases.

The HD foam 3 further includes the soft layer 31 and the supporting layer 32 disposed below the soft layer 31. The soft layer 31 is disposed, which not only enhances the comfortable feeling, making the user feel the mattress being softer, but also functions as a vibration absorber, reducing impulse when the user lies down. Soft layer 31 protects the supporting layer 32.

The HD foam 3 is made of 2,4-tolylene diisocyanate (TDI) and poly propylene glycol (PPG), the memory foam 2 is made of diphenyl-methane-diisocyanate (MDI) and poly propylene glycol (PPG). Other combinations of materials can be used as well.

Preferably, the density of the supporting layer 32 is greater than that of the soft layer 31. The soft layer 31 and the supporting layer 32 have a density ranging from 20D to 30D. More preferably, the soft layer 31 has a density ranging from 25D to 28D, and the supporting layer 32 has a density ranging from 27D to 30D.
