How fluid 3D Flotation technology works

The PURAP KIRO 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 seat 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.
KIRO's advantages over foam and gel cushions
Foam & Gel cushions
- Compress and pack-down according to body-weight distribution, creating 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 worsen pain, cut off blood flow, and cause heaviness & numbness in the legs.

+ Eliminates high pressure points (pressure hotspots) by dissipating pressure laterally
+ Provides relief from sitting pain, sciatica and bursitis, and absorbs vibration during driving.

Making a difference to people's lives
Torn hamstring attachment and torn piriformis
Ritag
I recently tore the tendon that attaches the hamstring to the ischial tuberosity (the "sit bone"), then not long after I tore the piriformis quite seriously. Since then, sitting puts weight exactly onto the injury site, and is brutally painful.
It seems that 99% of the seat cushions out there have a cutout for the tailbone (which transfers MORE weight onto the ischium, making it useless for this injury) -- the other 1% either have cutouts that are too small, or they're made of memory foam (which feels like sitting on a brick after a while), or they're just too thin and compressible.
This cushion has NONE of those drawbacks. It's not made of foam, so it doesn't compress. It doesn't have a cutout, so I don't have to wiggle around for 15 minutes trying to find the one tiny little spot that works. For me, the BEST part is what some reviewers didn't like -- it's liquid, like sitting on a small waterbed, so it doesn't feel "fixed" in place, it's always moving.
For this particular injury, this is PERFECT -- I can shift around to keep the blood flowing to the injury, and I never have a pressure point. I almost didn't try this one because so many people didn't like it. But now I have three -- one for my office, one for my car, and one for home.

I haven’t had any sitting pain since I started using it
N.B.
At first, I didn’t really see the benefits of this cushion. I am a 36 year old male and weight about 155 lbs. I sit long hours for work and have a 1 hour+ drive each way. I had started to feel a slight pain in my buttocks and a little numbness in my legs, especially after sitting for a while.
I ordered this cushion because a friend told me about it. I tried it on my office chair and initially found it strange because of the ‘floating’ sensation. I also expected to “sink” into the cushion similar to a foam cushion, but got a firm but floating feeling instead. After a day of trying, I thought of returning it because it seemed too expensive and wasn’t what I was expecting.
However, my friend convinced me to use it for a couple more days before returning it. So I did. I carried it with me to work, I used it in the car, and I used it at home. At the end of two days, when I was making a decision of whether to return it or not, I realized that I hadn’t had any sitting pain or leg pain since I started using it!
So I kept using it and haven’t had any kind of sitting pain since. The floating sensation does taking a little getting used to. The cushion will also ‘raise’ you by about an inch in your car, so you’ll have to adjust your seat a bit accordingly. But this cushion has helped me tremendously. I carry it around with me everywhere. I even use it while sitting at the dinner table!

Absolutely awesome product
Mary Pennington
I purchased this in August 2016. I have sciatica nerve problem which is aggravated by sitting for very long. Before I purchased it I called the telephone # listed and spoke to the founder of the company (George) about his product.
Within 2 weeks of receiving it I A) drove 12hr each way to Mississippi with 1 day in between drives and B) rode 1100 mile each way in diesel pickup truck(it rides really rough!) to Iowa with 2 day in between drives.
Normally after something like either trip I would be crippled up for at least a week with pain. I was a little stiff, but otherwise was fine. This is a fantastic product and I can't recommend it enough. I sewed a fleece covering with a handle for it so it can be carried easily and can be washed if needed. Thank you so much George for this product.

Butt and lower back issues
N.H.
I have tried a number of products and seem to always go back to the age old one of just sitting on a pillow. I have ischial bursitis and lower back pain primarily caused by my long drives down to LA and long periods of sitting at my desk. I think the two issues are related.
Heard about this product and decided I would give it a try. It is great. I can tell immediately that the cushion molds around my sitting area and takes the pressure off my butt.
I feel like it is putting me into a more upright sitting position because I am not trying to adjust to minimize the pressure points on my butt. No one actually sits in a level position, there is always some difference between the left and right sides, this cushion appears to level that sitting position because the cushion materials. I highly recommend it.
