Cantilevered Mattress Structure for Enlarged Sleeping Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses often lack sufficient surface area for comfortable sleeping, particularly for two people, and enlarging the sleeping surface area typically requires a specialized step deck or support structure.
Innovation Solution
A mattress design featuring an upper surface with a greater area than the lower surface, with extensions such as triangular or trapezoidal end surfaces that are integral with a core section, allowing for increased sleeping space without the need for additional support structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the sleeping surface area is enlarged by using a King or California King sized bed, then the sleeping comfort is improved, but the bedroom space requirement increases
Solution Approach 1:
The mattress utilizes a three-dimensional trapezoidal configuration where the upper surface area is enlarged by extending outward from the lower surface in a vertical dimension. This allows the sleeping surface to be larger than the footprint of the mattress base, effectively gaining sleeping area without proportionally increasing the space the mattress occupies in the bedroom.
2Area of moving object
If the sleeping surface area is enlarged by using a step deck support structure, then the sleeping comfort is improved, but the device complexity increases
Solution Approach 1:
The invention merges the mattress body and support structure into a single integrated unit. The trapezoidal configuration with extensions is built directly into the mattress construction, eliminating the need for separate step decks or specialized support structures. The mattress itself provides both the sleeping surface and the structural support.
Solution Approach 2:
The invention extracts and eliminates the complex step deck support structure from the system, replacing it with a self-contained mattress design that achieves the same enlarged sleeping surface area through its own geometric configuration rather than external support elements.

AI summary
A mattress comprises an upper surface and a lower surface opposite the upper surface. The mattress further includes first and second opposing side surfaces extending between the upper surface and the lower surface and third and fourth opposing side surfaces extending between the upper surface and the lower surface and between the first and second opposing side surfaces. A core section is formed by the upper and lower surfaces and first and second opposing core section side surfaces and third and fourth opposing core section side surfaces and an extension extends outwardly from a side surface of the core section. The extension is fixedly connected to or integral with the core section and the extension provides the upper surface with a greater area than the lower surface. The extension is capable of supporting a user without a support structure being positioned below the extension.
