Do you do the left-cheek-right-cheek dance?

You probably experience these symptoms when you sit for a while – a heaviness or numbness in your upper thigh, or a pain just on certain points of your buttocks, or a slight tingling in your legs, or strain on your back. And when you experience those, you do the dance without realizing it – the ‘shift your weight to the left cheek, then right cheek’ dance.

The root cause behind the dance

All these symptoms usually have the same root cause – your chair or cushion is putting pressure just on a few points of your buttocks, creating high pressure points (“pressure hotspots”). These pressure hotspots are basically taking up most of your body weight – that’s painful. It also restricts blood flow, which causes heaviness or numbness in legs, tingling, and even back pain as you adjust to avoid the pain.

The Zero-gravity pressure map

Pressure mapping shows that while other cushions create high pressure points (red and yellow areas), the PURAP U-Float cushion provides a low, more uniform pressure distribution.This provides superior pain relief and comfort.

  • No rebound. No high-pressure points

    Memory foam and gel cushions ‘rebound’. That slow rebound actually creates uneven pressure and high-pressure hotspots. The U-Float cushion eliminates these high-pressure points and provide a low, uniform seating pressure.

  • No ‘lock-in’ | Micromovements

    Other cushions are rigid and contour as per your body weight. That rigidity locks you in one position which increases pain and discomfort. Our cushion has a fluid layer than enables micromovements that help it easily respond to your position changes.

  • Thin. Flexible

    Those other cushions are thick and rigid, chunky slabs of gel or foam
    that are 2 inches, 3 inches, or even 4 inches thick. They may look comfortable but they function exactly the same as your chair or car seat. Our cushion is thin. Because it doesn't need to be thick and raise you in your chair or seat. It needs to dissipate pressure and it's great at doing that.

Easy to find and order, for to me in good time in good condition


It works well, but I'D like it thicker.


I paid for 2 of these but only received one. Emailed but received no response. I don’t really know how good it is yet but just disappointed that I only received one. Such an expensive item


Thought it was going to be a piece of junk. But after receiving it, I would not take anything for it. I recommend it 100%

Relief, Finally!

I have struggled for years with terrible pain in my tailbone when sitting for any length of time. As any sufferer knows some chairs are better than others but road trips and airplane trips are the worst. You are completely stuck and there is no relief in site.

I have tried many types of cushions and although many provided some relief they also caused other problems because they were 3” - 4” thick. I was on a mission to find something that would relieve my pain and I stumbled across the Purap 3D cushion. Yes it was more expensive than any of the other I had purchased in the past but I did not care, I was desperate.

To my surprise this cushion is AMAZING. My pain is gone. I have NO pressure points on my butt at all and the back on my legs don’t hurt either because of its very thin design.

I am so thankful I for your company it has literally changed my life. Thank you for everything
