Abstract

An aspect of the present invention relates to a method and system of receiving information of a user'"'"'s support facility comfort requirements; using a software application to determine a proper support facility firmness configuration to match the user'"'"'s requirement; selecting foam springs with the proper user required firmness as determined by the software application; and configuring the selected foam springs within the support facility to match the user'"'"'s firmness requirements.

Claims

1. An apparatus, comprising

a plurality of foam springs arranged in an interior portion of a mattress;

a webbing removably and replaceably attached to the mattress, the webbing securing at least two of the plurality of foam springs in a predetermined location within the mattress, and an attachment device that attaches at least two of the plurality of foam springs to each other,

wherein the webbing includes one or more openings that permit each of the at least two of the plurality of foam springs to be independently removed from and replaced to the predetermined location within the mattress.

2. The apparatus of claim 1, further comprising:

a foam layer positioned above the foam springs and within the interior portion of the mattress; and

a foam layer positioned below the foam springs and within the interior portion of the mattress.

3. The apparatus of claim 1, wherein the webbing partially encases the foam springs.

4. The apparatus of claim 2, wherein the webbing is a fabric.

5. The apparatus of claim 1, wherein the attachment device includes glue.

6. The apparatus of claim 1, wherein the attachment device includes hook and loop fasteners.

7. The apparatus of claim 1, wherein the attachment device includes tape.

8. The apparatus of claim 1, wherein the attachment device includes a snap.

9. The apparatus of claim 1, wherein the attachment device includes a clip.

10. The apparatus of claim 1, wherein the attachment device includes elastic.

11. The apparatus of claim 1, wherein the attachment device includes a buckle.

12. An apparatus, comprising

a mattress that defines an interior region;

a webbing associated with the mattress and positioned within the interior region;

a plurality of foam springs adapted to be positioned in an interior region of the mattress;

wherein a first foam spring of the plurality of foam springs is characterized by a first firmness and a first visually observable indicia that correlates to the first firmness;

wherein a second foam spring of the plurality of foam springs is characterized by a second firmness and a second visually observable indicia that correlates to the second firmness;

wherein the webbing includes a plurality of openings that permit each of the first and second foam springs to be independently positioned relative to the plurality of openings based on a predetermined firmness configuration.

13. The apparatus of claim 12, wherein the first firmness and the second firmness are different from each other, and wherein the first visually observable indicia and the second visually observable indicia are different from each other.

14. An apparatus, comprising

a mattress that defines an interior region;

a webbing associated with the mattress and positioned within the interior region;

a plurality of foam springs adapted to be positioned in an interior region of the mattress;

wherein a first foam spring of the plurality of foam springs is characterized by a first density and a first visually observable indicia that correlates to the first density;

wherein a second foam spring of the plurality of foam springs is characterized by a second density and a second visually observable indicia that correlates to the second density;

wherein the webbing includes a plurality of openings that permit each of the first and second foam springs to be independently positioned relative to the plurality of openings based on a predetermined density configuration.

15. The apparatus of claim 14, wherein the first density and the second density are different from each other, and wherein the first visually observable indicia and the second visually observable indicia are different from each other.
