Adjustable Mattress Wrap for Pillowtop Firmness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pillowtop mattresses often lack sufficient firmness and support, which can lead to discomfort during sleep, despite their initial appeal due to softness.
Innovation Solution
A rectangular sheet of fabric with adjustable hook and pile fasteners is wrapped around the mattress to compress the pillowtop area, increasing firmness by applying uniform pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pillowtop mattress is made soft to attract consumers, then initial appeal and comfort are improved, but firmness and support deteriorate
Solution Approach 1:
The patent applies a dynamic adjustment mechanism by introducing an adjustable tensioning system with hooks and eyes that allows the mattress cover to be tightened or loosened. This enables the mattress to transition between soft and firm states, resolving the contradiction between initial softness appeal and sustained firmness support.
Solution Approach 2:
The patent changes the physical parameter of tension applied to the mattress cover by providing adjustable fasteners that can modify the tightness of the cover over the pillowtop. This parameter adjustment directly controls the firmness level, allowing the mattress to maintain both softness appeal and firmness support as needed.
2Strength
If the mattress structure is altered to increase firmness, then support is improved, but device complexity increases
Solution Approach 1:
The patent introduces a intermediary element - the adjustable mattress cover with tensioning system - that acts as a mediator between the user's firmness requirements and the mattress structure. This cover system provides the firmness adjustment function without requiring modification of the mattress's internal construction, thereby avoiding increased device complexity.
Solution Approach 2:
The patent segments the firmness adjustment function from the mattress structure itself by using a separate, removable cover system with independent tensioning mechanisms. This segmentation allows firmness control without altering the core mattress construction, maintaining simplicity while achieving the desired firmness enhancement.
3Strength
If existing patent solutions are implemented (inflatable cushions, stacked elements, cross-pieces), then firmness control is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the firmness control function from complex mechanical systems and simplifies it to a basic tensioning mechanism using a cover with hooks and eyes. This extraction removes unnecessary complexity while retaining the essential function of firmness adjustment, avoiding the need for inflatable cushions, stacked elements, or adjustable cross-pieces.
Solution Approach 2:
The patent employs a simple, inexpensive mattress cover with basic fasteners that can be easily manufactured and replaced if needed. This approach uses low-cost materials and simple construction rather than expensive, complex mechanisms, achieving firmness control through an economical solution that doesn't require durable, complex components.

AI summary
A method for increasing the firmness of a pillowtop or any other soft mattress. The method includes providing a rectangular sheet of cotton fabric material having hook fasteners on one end and loop fasteners on an opposite end to attach the sheet of material around the mattress. The firmness of the mattress is increased by tightly wrapping the sheet of material around the mattress using the fasteners. The sheet of material is sized appropriately to fit entirely around the mattress with overlap. Preferably, the sheet of material is sized and manufactured for wrapping longitudinally around the mattress.
