PURAP Pressure sore Cushion


The PURAP cushion uses our fluid 3D Flotation technology to provide the lowest peak pressures while sitting. It can be used in wheelchairs, recliners, lift chairs, and any other chairs.

- Prevents formation of new pressure sores

Helps existing sores heal faster

Provides relief from sitting pain


Blue: $129   |   Black: $139

How fluid 3D Flotation technology works

The PURAP cushion uses 3 layers - fluid, air, and foam - to dissipate pressure. The fluid layer is closest to the body. It fills in all the space between you and the cushion and increases direct support area. It does not compress and does not push back (like springs). This helps it dissipate the pressure away from the body towards the sides of the cushion.

Fluid 3D Flotation eliminates peak pressure points (pressure hotspots)

Increases contact area to dissipate pressure, provide uniform support

Does not 'pack-down' or 'sink-in' and doesn't lock you in one position

Fluid micro-movements avoid pressure buildup

Born from personal experience

Sores can start developing within 2 hours. Once sores form, they are extremely difficult to get rid of. We should know.

One of our founder's father-in-law developed a bedsore while at a skilled nursing facility. None of the existing products helped and he ultimately passed away due to complications related to his sores.

Our search for something that actually worked led us to create the 3D Flotation technology and our anti-sore products.

PURAP's advantages over foam and gel cushions

Foam & Gel cushions


- Create a highly uneven pressure distribution

Concentrate pressure only on a few contact points (typically areas below your sit bones)

These areas become high pressure points or "pressure hotspots" that cause pain, cut off blood flow, and create pressure sores.
