This cushion fits most wheelchairs, recliners, lift chairs, dialysis chairs, and home chairs and can be used at the hospital, care center or at home. It helps those who are disabled, have limited mobility, or are elderly.

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.

So for so it’s been good

I just got it the other day and my bottom started hurting again from being in the bed itand my son put it underneath me and in a few minutes I could feel the difference and my butt felt a lot better. I will use it again when I go outside in my power hair or wheelchair and see how it does with them!!
