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.

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.

Great product, delivers the desired comfort
Jim Ono
I have a "cranky" back, not a bad back but put to stress it gets cranky, which I define to mean getting a strong feeling of tightening up and unable to be reasonably flexible. As a decent golfer, this is not good. I bought the lumbar support from this company because I previously purchased their seat cushion and was highly impressed with the quality and delivering the desired goals; comfort and lack of discomfort!
This particular product, is like the seat cushion in that, what's important is the ABSENCE of discomfort at the end of the trip. In the past, after any trip over 1/2 hour, I'd have a sore butt or cranky back that took time to work out its kinks! A long trip was hell. Now, after it's over, what's nice is the absence of discomfort; I just get up and go on without having to work out the kinks. That's makes the product 5 stars because, it delivered the desired goals/objectives and I'm happy with the result.

Does the job and feels really premium
Amazon Customer
I have been using this back support cushion since a few months now at my home study chair. It is so comfortable, that I got a second cushion a couple of weeks back from Amazon for my office work chair.
I am an engineer who is used to working long hours sitting in the same spot staring at the computer. This has taken a toll on my back and neck over a period of time, but since I started using this product, I see that I have reduced the stress on my lower back significantly, and with that even the neck pain reduced.
Pros: 1) Good material, looks and feels premium. Is premium quality. 2) Really feels good on the back and comfy. 3) Adapts really well to the contour of the chair, filling up the space between your back and the chair.
No cons yet. I guess it justifies its price, by saving a lot of money on doctor/ chiropractic visits and physiotherapy 🙂

For the first time, my back feels supported
Anonymous
Working at the computer has the downside of needing to sit for really long hours. I thought I'd try this cushion for extra back support and I haven't been disappointed so far.
The back of most chairs can get a little uncomfortable after a while and I have never felt full support for my back. I decided to try the KIRO Oasis Back Cushion because the “fluid” approach made me curious.
For the first time in my life, my back feels supported by my chair. I’ve tried the cushion on a bunch of chairs in my office and at home, and the cushion supports my back in all of them.
