Foam Spring Mattress Configured With Variable Firmness

A method of re-configuring a foam spring mattress, comprising:

• assigning a relevance rating to a foam spring location in the mattress, wherein the relevance rating relates to the relevance of the location to the impact it has on the firmness feel of the mattress;
• configuring a plurality of foam springs of varied firmnesses in a mattress according to a first placement pattern to obtain a first firmness, wherein the first placement pattern is generated based on a match between a foam spring of a particular firmness and the relevance rating;
• and
• re-configuring the plurality of foam springs of varied firmnesses in the mattress according to a second placement pattern to obtain a second firmness, wherein the second placement pattern is generated based on a match between a foam spring of a particular firmness and the relevance rating.

A mattress comprising:

• a containment facility;
• a plurality of generally barrel shaped foam springs each having a side surface and a pair of opposed end surfaces, the plurality of foam springs being disposed side by side in the containment facility such that the side surfaces of the foam springs are in contact with each other, the foam springs being individually removable and replaceable in the containment facility;
• each of the foam springs having a firmness selected from a plurality of different firmnesses, the color of each foam spring providing an indication of the firmness such that springs with different firmnesses have visually distinguishably different colors;
• and
• the plurality of difference firmnesses and associated colors such that the plurality of foam springs form a color pattern indicative of a firmness profile of the mattress.
