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.
