Pressure Testing

Our tests to identify the level of these high-pressure readings were conducting using a BodiTrak pressure sensing mat which records the data in millimeters of Mercury (MM/HG, blood pressure). Through our research we determined that consistent readings above 100 MM/HG were shown to be undesirable. Our final product design has produced results that are significant improvements as shown in the following data.

The following results are from tests on a popular seat used on trucks and heavy equipment. The tests were conduction using a male subject weighting 245 pounds and generally last 15 minutes each. Data is collected every 15 seconds with a total of 43 readings taken in each test. We tested a variety of cushioning materials such as molded Gels, Elastomeric and foam style cushions. Gel styles were as successful as our 3D engineered cushion, but they were heavy, weighting up to 3 pounds and thicker at 1 3/4” to over 2 1/2”. Aside from portability issues, they were easily damaged if left in a vehicle when internal temperatures reached 100 degrees or higher.

Testing Methods:

Participants: 234-pound male and a 135-pound Female.

Cushion: 234-pound male, tested on a seat cushion commonly found on trucks and heavy mining equipment.

Data is collected every 15 seconds a total of 43 times and is measured in terms of MM/HG or blood pressure readings.
