Claims10
A mattress apparatus, comprising:
- a base portion including a top surface, a bottom surface, opposing side surfaces that include a head side surface and a foot side surface, and defining a longitudinal axis from the head side surface to the foot side surface;
- a relief volume within a sub-portion of the top surface, the relief volume defined by a relief periphery within the opposing side surfaces of the top portion and side walls extending vertically downward by a vertical distance into the base portion from the relief periphery, wherein the relief periphery defines a rounded shape;
- a set of two or more central insert elements, wherein each central insert element is shaped such that each central insert element, when inserted into the relief volume, has a first side wall and a second side wall that abuts at least a portion of a first side wall and a second side wall of the relief volume that are opposing each other on opposite sides of the longitudinal axis, and has a third side wall and a fourth side wall that is spaced apart from a third side wall and a fourth side wall of the relief volume to form respective first and second peripheral volumes within the relief volume and that are respectively intersected by the longitudinal axis, wherein each insert element has a rounded periphery formed by the first, second, third and fourth sidewalls of the central insert element, and the first peripheral volume and the second peripheral volume are on opposite sides of insert element;
- for each first and second peripheral volume, a set of one or more peripheral insert elements, wherein each peripheral insert element is shaped such that when inserted into the relief volume, side walls of the peripheral insert element abut the third side wall or the fourth side wall of a central insert element that is in similar vertical disposition with the peripheral insert element, and abut the third side wall or the fourth side wall of the relief volume, wherein each peripheral insert element is crescent shaped;
- each central insert element has respective top and bottom surfaces spaced apart by a respective height that is less than the vertical distance by which the side walls of the relief volume into which the central insert elements are received extend downward;
- each peripheral insert element has respective top and bottom surfaces spaced apart by a respective height that is equal to or less than the vertical distance by which the side walls of the relief volume into which the peripheral insert element is received extend downward;
- the central insert elements and the peripheral insert elements may be individually and separately placed within the relief volume so that a plurality of adjusted relief volumes may be formed, wherein each adjusted relief volume is oriented differently from each other adjustable relief volume;
- and
- the relief periphery of the relief volume matches the periphery of the central insert element abutted on opposite sides by the peripheral insert elements.

- a relief volume within a sub-portion of the top surface, the relief volume defined by a relief periphery within the opposing side surfaces of the top portion and side walls extending vertically downward by a vertical distance into the base portion from the relief periphery;
- a set of two or more central insert elements, a first set of one or more peripheral insert elements, and a second set of one or more peripheral insert elements, wherein:
- each central insert element has a rounded periphery such that each central insert element, when inserted into the relief volume, fills a central portion of the relief volume and is spaced apart from opposite side walls of the relief volume that are respectively intersected by the longitudinal axis to thereby define a respective first peripheral volume between a first portion of the relief periphery and a first portion of the rounded periphery of the central insert element, and a respective second peripheral volume between a second portion of the relief periphery and a second portion of the rounded periphery of the central insert element;
- each peripheral insert element in the first set of one or more peripheral insert elements has a first periphery portion that is rounded to match the first portion of the relief periphery, and has a second periphery portion that is rounded to match the first portion of the rounded periphery of the central insert element, and that when inserted into the first peripheral volume, fills at least a portion of the first peripheral volume;
- each peripheral insert element in the second set of one or more peripheral insert elements has a first periphery portion that is rounded to match the second portion of the relief periphery, and has a second periphery portion that is rounded to match the second portion of the rounded periphery of the central insert element, and that when inserted into the second peripheral volume, fills at least a portion of the second peripheral volume;
- each central insert element has respective top and bottom surfaces spaced apart by a respective height that is less than the vertical distance by which the side walls of the relief volume into which the central insert elements are received extend downward;
- each peripheral insert element has respective top and bottom surfaces spaced apart by a respective height that is equal to or less than the vertical distance by which side walls of the peripheral volume into which the peripheral insert element is received extend downward;
- the central insert elements and the peripheral insert elements may be individually and separately placed within the relief volume so that a plurality of adjusted relief volumes may be formed, wherein each adjusted relief volume is oriented differently from each other adjustable relief volume.
