Introducing our New Interactive Data Exploration Tool

At the University of Pittsburgh’s Rehabilitation Engineering Research Center (RERC), the University of Pittsburgh Wheelchair and Cushion Standards group has applied a subset of test methods from the ISO 16840 standard suite to a diverse cohort of approximately 50 cushions. This web-based interactive tool has been created to allow stakeholders to explore our independently generated cushion performance data. The cushions are not identified by name but by cushion categories. You can sort cushion performance by broad cushion category or CMS code. The performance data includes a reference cushion, which is a 3” thick, high density polyurethane foam cushion with a 25% IFD of 170 N and 65% IFD of 320 N.

ISO 16840-2:2018 Clause 11 – a test to evaluate a cushion’s ability to immerse the buttocks
ISO 16840-2:2018 Clause 9 – a test to evaluate a cushion’s ability to reduce impact loading on tissues and help maintain postural stability when performing tasks such as going off a curb
ISO 16840-2:2018 Clause 14 – a test to evaluate the cushion’s ability to consistently provide support during a cycle of loading and unloading
ISO 16840-2:2018 Annex C – a test to evaluate the cushion’s response to slight horizontal movements in the forward direction
ISO 16840-13:2021 – a test that characterizes a cushions’ ability to resist lateral leans
ISO 16840-6:2015 Clause 14 – a test that utilizes interface pressure measurements to assess the magnitude and distribution of pressure on a loaded cushion
ISO 16840-6:2015 Clause 20 – a test to evaluate a cushion’s ability to “cushion” or elastically deform by measuring the force necessary to produce a deflection of 10% of the cushion thickness
