Benefits of technology

[0011] The invention provides an inflatable device that is placed between the mattress and box spring and enabling the user to adjust the firmness, support, and sag. The inflatable convex mattress adjustment device acts like a board that can be infinitely adjusted in the proper proportions (the convex shape).
[0016] 3) A single device generally controls the firmness, support, and sag of the majority of a single sleeping area. That is, not just the head region, spine region or leg region, but the majority of the area that gets depressed as a person lies upon a mattress.

Problems solved by technology

After experimenting with different prototypes, it became apparent to this inventor that a convex shape is highly desirable, and an inflatable device without controls to maintain the convex shape would not be stable.

Embodiment Construction

[0039] The invention provides a convex-shaped, inflatable mattress support (see FIG. 1), with a structural design to help form and maintain the convex shape. The device is designed to adjust the firmness and support of the general area of a mattress, not just a specific area of the body, such as the head or spine.

[0040] When looked at from the side (see FIG. 1), the convex shape would be widest in the middle and tapered towards the perimeter. This shape closely matched the concave shape of a sagging mattress or a mattress with the weight of a human applied. (see FIGS. 2A and 2B)

[0041] This invention would include structural design to help maintain the convex shape. Without such a structure, a device of that size would squish and bulge, making the device unstable and ineffective. (see FIGS. 3A and 3B).

[0042] One structural design used to help maintain the shape of the device is shown in FIG. 4A-4C. These figures depict pieces of flexible material connected the top and bottom of th...

Abstract

Apparatus for adjusting the firmness, support, or sag of a mattress includes an inflatable device having a substantially convex cross-sectional shape that is thicker in the center region and gradually thinner toward the edges, a material and constitution for maintaining the convex shape under the weight of the mattress and a person, and a set of dimensions large enough to adjust firmness, support, or sag for the majority of an area of the mattress used by the person.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention pertains to the field of mattresses and box springs. More particularly, the invention pertains to means for adjustment of firmness, support, and sag of a mattress. [0003] 2. Description of Related Art [0004] U.S. Pat. No. 4,745,645 to McWilliams discloses is an “Inflatable Insert for Worn Mattresses,” which has three separate rectangular, flat, pleated pads. It does not teach a one-piece unit having a convex shape. [0005] U.S. Pat. No. 5,070,559 to Pettifer discloses an “Adjustable Spinal Support,” which is designed to help support the “lumbar region of a person's spine” and does not teach a convex shape. [0006] U.S. Pat. No. 5,948,013 to Swezey et al. discloses a “Self-inflating Back Pillow and cold Therapy Device”. While this patent teaches a convex shape, it is a much smaller device used to support the lumbar region of chairs. [0007] U.S. Pat. No. 6,665,898 to Gordon teaches a “Device for correcting...
