Add comfort to your ride 

Our seat cushion significantly increases comfort through weight re-distribution on the seat surface improving blood flow to the lower extremities. The immediate effect from the use of our Comfort Cushion is a noticeable reduction of the pain and discomfort caused by the lack of oxygen to the lower body muscles. This is common outcome on a wide range of seating utilizing molded foam cushions covered by a tight form fitted upholstery.

Designed for use on truck, heavy equipment and car seating.

Comfort Cushions are designed for all trucks such as Peterbilt, Kenworth down to smaller city delivery trucks and parcel vans right up to 400 Ton Caterpillar and Komatsu haul trucks. They are ideal for long distance trucker and mining equipment operators where shifts can go well beyond the normal eight-hour shift.

The standard Personal Use Cushion is approximately 18” X 18” X ½” thick. and is constructed from 2 layers of Engineered 3-D Spacer fabric and weighs only 7 ounces. It easily folds into a compact 9” X 9” X 2” package making it easy to carry around. The result is it works better than we expected, extensive field testing and sales over a 6-month period have not produced a single negative comment or product return.

When you first use this “comfort cushion” you should experience a heighten sense of comfort. Over time you this improved level of comfort will be accepted as being normal which may lead you to believe it is providing no additional benefit. If that occurs, remove the cushion from use, at that point you will recognize its’ true value.

Our cushion is “Proudly made in the USA”. All materials and manufacturing are 100% USA sourced. Our production is sourced at a fair living wage that we consider as being well above average.

Distributes weight and reduces high pressure points

We immerse the body into the seat cushion and distribute the weight over a greater area and improving the flow of blood to your lower extremities. The benefit is no pain or discomfort, or swollen ankles. Minimal pressure points equals more comfort. We not only reduce the high MM/HG readings down to a manageable level we also reduce the number of them by 70% to 100% depending on your cushion. 100 % breathable, remains cool, does not absorb moisture. Thinner and lighter than 2 to 3 inch thick “gel” cushions making them easier to carry and for getting in and out of your seat.

Testing and Product Development

To begin the process an engineer was employed to develop a suitable testing protocol to evaluate seating comfort and test methods. The BODI-TRAK pressure sensing mat was chosen to do what is known as Body pressure sensing. We began the testing by selected a range of “gel”, “foam” and “elastomeric” cushioning materials available in the market. We selected cushions from 5 popular seats in use in the trucking and heavy equipment market. The test subjects were a female at 145 pounds and a male at 235 pounds.

With the testing of the selected common cushioning materials we achieved acceptable results but felt they were not marketable. To get the best results from “Gel” material we found the we had to use thicker cushions between 2” and 3”. While cost effective we felt that in actual use there would be difficulties getting in and out of seat with cushions of this height. Added to that, portability was a problem with the cushions weighing being between 2 to 3 pounds each compounded by the fact they could not be easily folded into a small portable package.  The foam products were lighter but also presented heat retention, thickness and portability issues.

The “elastomeric” cushions produced very acceptable comfort outcomes, they were very light and foldable for portability. However, from the cost standpoint they would require a complex manufacturing process that was very costly.

At that point we began searching for alternatives and through research found what is known as 3-D Spacer fabrics. This material can be engineered to obtain different outcomes such as shock and vibration mitigation, stab protection and beneficial cushioning properties. We found a USA based producer that we were able to work with in developing a suitable material for testing purposes.

The fabric consists of 3 components, a top and bottom layer inter-connected by vertical fibers

The fabric consists of 3 components, a top and bottom layer inter-connected by vertical fibers. By varying the diameter, number of fibers per given area, fiber properties and the orientation of the interconnecting fibers various cushioning outcomes could be achieved.

In our case we produced a 3-D fabric with a stiffness property that could support a seated body comfortably.

Pressure Mapping

Using our BODI-TRAK pressure mapping system we were able to conduct tests to determine how well the 3-D engineered fabric supported our 2 test subjects on range of seat cushions that are common on trucks, buses and heavy machinery. The BODI-TRAC mat records the distribution pattern and pressures exerted by the seated body on the seat cushion. These readings are given in terms of MM/HG, milligrams of mercury, the same as used in blood pressure readings. While there is no established standard for the readings for body pressure mapping, for our purposes we determined that readings less than 100 MM/HG would be beneficial in promoting blood flow to the lower extremities while seating for extended periods. While we have not eliminated the readings over 100 MM/HG we have substantially reduced them to manageable level by 70% or higher, and in one case by 100%. We have also significantly reduced the number of the readings over 100 MM/HG. In some recorded cases these readings reached 185 MM/HG on some cushions which we consider as not being healthy.

Using our two test subjects we conducted over 228 individual pressure tests with 151 devoted solely to our 3 D spacer fabrics. In all tests the improvements were dramatic, reducing both the number of pressure points over 100 MM/HG and the high levels.

At the end of this document we will present 2 sets of tests with and without our “comfort cushion” using the same test seat that will clearly demonstrate our significant improvements.

WHY OUR CUSHION WORKS: When our cushion is used on top the original OEM seat cushion it increases the area of the body in contact with the seating surface. The simple explanation is that with the increased contact area your weight is supported across a larger area and therefore reducing the pressures exerted.

Basically, when you sit in a standard truck, airplane or heavy equipment seat you sit “on the seat cushion”, when you add our cushion you sit “in” the seat thereby increasing the support area and spreading the weight over a greater area.

The benefits are an increased flow of oxygen rich blood to the lower extremities, eliminating the common aches, pains and swollen legs.

BODY PRESSURE MAPPING TESTS

The following are the results of body pressure mapping conducted on a popular seat widely used in the mining industry and on truck seats commonly found in Europe and Australia.


TEST 115 ISRI CUSHION

Pressure Points Over 100 mm/Hg = 606
Maximum Pressure = 144 mm/Hg


TEST 117 ISRI CUSHION w/ 2 layers
