How fluid 3D Flotation technology works

The PURAP mattress uses a patented system with a unique fluid layer that dissipates pressure. The fluid layer fills in all the space between you and the mattress overlay 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 pad.

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 outperforms alternating air and gel overlays

Air, Gel and Foam Mattresses and Overlays
- Compress and contour 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 cause pain, cut off blood flow, and create pressure sores.

Better than I could've imaged

I was desperate when I ordered this for my Mom. She regularly got pressure sores on her hips that made sitting in chairs or lying in bed a real torture. We tried wedges to keep her lying on her side in bed. I bought special cushions and "egg crates" for every chair, most purchased from Amazon.
Mom's sores would go away for awhile, but they always returned in a couple of weeks. Then I searched Amazon again for another solution and discovered the PURAP. I hesitated a long time because of what I thought was a very high price. But then, I'd bought special chair cushions for $100 that were practically useless after a short time. I'm thrilled to say that as soon as the PURAP arrived, the sore that had plagued her for a week just began to disappear. Frankly, I was afraid to credit the PURAP -- nearly any cushion had seemed to work in the short term.
But now on June 2, I can report that Mom has not had a single sore or any discomfort, whether sitting in a chair or lying in bed, since the PURAP arrived in mid-March. This is the longest time she's had this kind of relief and comfort in a year. I am so grateful that all I can say is "Thank you, PURAP!" And to anyone else with an elderly parent who hesitates because of the "high price," I assure you that in my house, this solution is considered priceless.

Healed sores and prevented further skin breakdown.

I ordered this cushion for my mother to heal and prevent future bedsores as she was mostly bedridden but preferred to sit more upright. This created a real problem at her coccyx and left buttock. No mater how I tried to get her to reposition herself she would always go back to this position making her sores worse.
Purap was amazing... it not only prevented further sores but the two she had (stage 1) healed within a few days! The Hospice nurses and CNA's were impressed with the results, too. With this she was able to remain sore-free even after spending nearly a month completely bedridden at the end of her life (and still managing to move herself into her favorite position). I highly recommend this product!

Having had several separate skin shears in bed with my very thin, fragile, post SCI skin, over sharp bones occurring on my lower spine and tail-bone, several times over the past 8 months, I wanted to find the best long term solution. Since I now can not lay on my side for long periods, & I don't have care avaliable to be turned regularly, I decided to personally give the Purap bed system a try, having previously compared its pressure mappings against my Roho. I was impressed that the Purap was both lower & uses a shear free system to prevent that type of injury in the future.
Since I have my caregivers check my skin every morning & evening I can tell exactly what is going on. What I found was the Purap system not only provides better protection than the Roho, it additionally enabled me to rapidly heal from my last tailbone injury
.But healing wounds with the help of a Purap product is not a new experience for me. I also have been able to heal from wounds while sitting up in my wheelchair with the help of Purap's chair cushion & measuring the pressures to verify my best options.
