Why do wheelchair users need a special cushion?

Wheelchair users sit for longer periods and are usually unable to shift positions frequently and/or on their own. The constant pressures on few points of the buttocks create pressure sores. Sores are extremely painful and can get infected and worsen very quickly. A well-designed wheelchair cushion helps eliminate high pressure points and prevent and heal sores.

How does PURAP prevent and heal sores?

Memory foam and gel cushions ‘rebound’ and push back against your bottom, creating high pressure points (red areas on the pressure map). PURAP uses layers –fluid, air, and foam – to fill in the uneven body surface and increase the support area for your bottom. The fluid layer also moves freely in a bladder and helps eliminate high pressure points to provide uniform support and stability (blue and green areas in the pressure map). This helps heal and prevent bedsores.

Hear from our customers

  • No slow rebound

    Memory foam and gel cushions ‘rebound’ over time, trying to get back to their original shape. That slow rebound actually creates uneven and high pressures. Our cushions reduce sore-causing high-pressure points and provide continuous low, uniform seating pressures.

  • No rigid, pre-contoured shape

    Other cushions are rigid, pre-contoured, and have a one-shape fits-all contour. That rigidity locks you in one position and magnifies high pressure points. Our cushion has a fluid layer that enables micromovements that help it easily respond to your position changes.

  • Thin. Flexible

    Most other cushions are thick and rigid chunky slabs of gel or foam that are 3 or 4 inches thick They increase seating height which reduces comfort and ‘fit’ in most seats. Our cushion is much thinner and does not raise you significantly, does not alter your ‘fit’ in the seat, and dissipates high pressures effectively.

Flotation pillo

I purchased this pillow for my elder mother. She loves it. She sleeps with it under her and I put
It on her chair and wheel chair. We’re ever she sits the pillow goes with her

Don’t hesitate to buy! Amazing!!!!

My father’s been suffering from pressure sores from sitting in a lift chair due to his ALS. We have tried several cushions and he has gotten no relief, just agony. I was googling one day and found this cushion, and we decided to give it a try. Wow oh wow it has been amazing! I wish all the doctors and the pain clinic we visited had known to tell us about this cushion because he would’ve found relief a whole lot sooner! I’m going to try and get the word out to them, so no other patients suffer like he has. Thank you thank you thank you for making this product!!!

Help is here.

After 6yrs in a wheelchair and riding around on 3 to 4 inches of foam and gel cushion caught up with me. Started getting pressure sores on rear end and had to do some adaptive changes. That includes the Purap cushion I purchased online. Immediately healing started and cleared the ulcer. Wonderful cushion, and uncomplicated.

Life saving cushion for my tush!

I have wasted so many hundreds of dollars trying to find a cushion that relieves pressure, comfortable, made to last and easily moved from wheelchair to recliner.

I have ALS, I'm literally 24/7 in a wheelchair or recliner (I also sleep in recliner); my tush never gets relief UNTIL this magical cushion arrived.

The cushion has relieved pressure pain which has allowed my tush sores to start healing quickly when nothing previously helped in the keast. If I die today, I'll die with a pain free tush and that's worth more than words can ever express.

I've left instructions that my wheelchair be donated to another ALS victim. Now this cush for my happy pain free tush will go with the wheelchair.

I purchased my cushion off Amazon


These are the best cushions ever for preventing and/or healing pressure sores on those who are chair or wheelchair bound. Had tried many others, including "waffle" air cushions, but only Purap has solved the problem. Thank you!
