Mattress assemblies including a hybrid posture support system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattress assemblies often fail to provide adequate posture support and pressure relief, leading to discomfort and potential spinal misalignment during use.
Innovation Solution
A hybrid posture support system for mattresses, comprising a top foam layer with spaced apart first and second foam portions corresponding to the head/shoulder and foot regions, a pocketed microcoil array underlying the top foam layer, and an underlying foam layer, which can be integrated with either a coil spring or foam innercore, enhancing spinal alignment and air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mattress assemblies use uniform foam layers, then manufacturing is simple, but posture support and pressure relief are inadequate
Solution Approach 1:
The mattress is divided into multiple functional zones: a top comfort layer with varying density foam for pressure relief, a transition layer with different firmness, and a base support layer. This segmentation allows each layer to perform its specific function optimally, providing adequate posture support while maintaining manageable manufacturing complexity through modular construction.
Solution Approach 2:
Different regions of the mattress employ different foam densities and firmness levels tailored to specific body areas. The top layer uses softer foam for pressure-sensitive areas like shoulders and hips, while the base layer provides firmer support for spinal alignment. This local differentiation of material properties enhances posture support without requiring complete structural redesign.
2Reliability
If memory foam is used to conform to user shape, then pressure points are minimized, but air flow is reduced
Solution Approach 1:
The mattress incorporates foam materials with controlled porosity and open-cell structures that allow air circulation while maintaining the conforming properties of memory foam. The porous architecture enables breathability through the comfort layers, preventing heat buildup and improving air flow without sacrificing pressure relief capabilities.
3Reliability
If multiple foam layers with varying properties are used, then user comfort is improved, but manufacturing complexity increases
Solution Approach 1:
The multi-layer construction is organized into distinct modular layers with clear interfaces, where each layer can be manufactured separately and then assembled. This segmentation simplifies the manufacturing process by allowing specialized production of each layer type before final assembly, reducing overall fabrication complexity despite the variety of foam properties required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hybrid posture support system provides improved posture support, pressure relief, and proper spinal alignment, while the pocketed microcoil array increases air flow when combined with a coil spring innercore, accommodating various mattress sizes and user preferences.
Implementation Method 1
a pocketed microcoil array underlying the top foam layer intermediate and abutting the spaced apart first and second foam portions, wherein the microcoil array comprises a plurality of microcoils arranged in columns and rows encased in a fabric
Implementation Method 2
These foams are often open cell foam structures having both closed and open cells but in some instances may be reticulated foam structures. When used in a mattress, the memory foam conforms to the shape of a user when the user exerts pressure onto the foam, thereby minimizing pressure points from the user's body.

AI summary
Mattress assemblies include a hybrid posture support system that provide an end user with improved posture support during use, among other advantages. The hybrid posture support system includes a top foam layer including first and second foam portions that are spaced apart and generally correspond to a head/shoulder region and a foot region, respectively, a pocketed microcoil array underlying the top foam layer that is intermediate the first and second foam portions; and an underlying foam layer. The hybrid posture support system can be used in any mattress assembly including mattresses having a coil spring innercore or a foam innercore.
