PURAP Bedsore Seat Cushion
The PURAP seat cushion for wheelchairs and recliners helps prevent and heal pressure sores. It 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: $139.99 | Black: $139.99

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.

![]() 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.

PURAP cushion
+ Fluid technology increases direct support area and distributes pressure more evenly
+ Eliminates high pressure points (pressure hotspots) by dissipating pressure laterally
+ Reduces pain, prevents and helps heal sores, and maintains skin microclimate

Making a difference to people's lives
Lifesaver for my mom
K.C.
I ordered this for my mom who spends a lot of time in her wheelchair and had started to regularly develop a pressure sore. She is in a first rate nursing home and lack of care is not the issue.
We have been emphatic about her being up in her wheelchair and participating in life and not laying around in her bed so the pressure on her tailbone became an issue. She had just developed another sore just before the cushion arrived. This time, with the cushion in place, the sore healed really, really quickly...like within a week.
Normally the staff would be nursing it along closer to 2 weeks or more before it would heal and the scab would fall off and then before we knew it another one would develop. It has now been almost a month and no new sore. We have all been checking her and there aren't even any red pressure areas on her behind anymore.

It is rather amazing
Selena D. (nurse)
I do not bother to write reviews. I am a nurse practitioner and have been a nurse for nearly 35 years. I bought this for my, now, 87 year old mother. I purchased this because she sits, ALOT, and she started to develop sores on her buttocks.
I tried various treatments I used in the past as a nurse, but the sores worsened. Well, after placing this pad on her chair, her sores healed without any other products on her skin! It is rather amazing.
I told my friend about this and her mother-in-law was in the same situation. It healed her ulcerations also. I believe her daughter also wrote a review. It really is amazing! My mother has had this on her chair in the living room for nearly 2 years. I recommend this to anyone. It certainly prevents the shearing and tearing of the delicate, fragile skin of the elderly. Thanks so much!!!!

Helped my mom during rehab
Quistan Thrand
I purchased this product because my Mother broke her hip and underwent hip replacement surgery. She has been working on rehabbing the "new hip" at a nursing home. Within a week of arriving at the nursing home she had developed bed sores on her dupa (tailbone and related areas).
These bed sores weren't due to neglect, but rather due to the fact she no longer has any layer of fat underneath her skin to act as a cushion. Knowing how fast bed sores can turn septic I frantically searched Amazon looking for some sort of product that would work to help heal the bed sores.
I found this patented PURAP cushion and bought it for her. The day my Mom received the cushion, she put it on the chair of her wheelchair and the pain was so much less when she sat on the pad she was able to spend more than half the day out of bed--which greatly facilitated her recovery. She now uses the pad to sleep on and also to sit on whenever she is in a wheelchair.

It does what it says and more
Lulu and Phoebe
I waited a couple of months to write this review because I wanted to see how it actually held up to daily use. It's used in a (Karman 305) wheelchair and it gets hours of use daily. Think 24/7.
It also gets tossed into the trunk of vehicles when the wheelchair is folded during transport. I was concerned that some of the layers would be compromised eventually but after a few months it looks like new. And it gets serious use and little thought.
It's like the invisible support it needs to be. One of the important selling points for me was that it did not raise the height of the person in the chair because the wheelchair seat, arms, back were ergonomically adjusted to meet that height. It stays in place, is easy for the user to slide forward to exit the chair and cleans easily with a wipe. Though it is slightly spendy, it is totally worth buying because the quality is stellar. I'd buy it again.
