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.

Helps maintain neutral spine position by helping the spine decompress

Absorbs vibrations and reduces risk of aggravating your back pain

Provides lumbar and upper back support 

Fluid micro-movements avoid pressure buildup

Medical use technology

The PURAP KIRO chiropractic back cushion uses fluid 3D Flotation technology that is used in our medical use cushions and mattress overlay. 

This technology provides the lowest peak pressures. It has been designed for heavy use all day and is ideal for those who sit long hours at work or while driving.

PURAP's advantages over foam and gel cushions

Foam & Gel cushions


Compress and push back creating high-pressure "pinching" points on your back.

- Pack-down and form a rigid contour, so you have to shift positions to find the "right" position to be comfortable.

- Are no different from your existing car and office chair backs and offer no advantages over them.


Normal foam 'contoured' lumbar supports

KIRO back cushion


Fluid technology distributes pressure more uniformly and helps the spine decompress.

Absorbs vibrations and dampens sudden movements which can aggravate back pain.

Does not pack down and form a rigid contour. Fluid micro-movements continually adjust so you don't have to find the "perfect" position.
