I currently own all 3 versions of this seat cushion and love it 😍. I have owned others from other manufacturers I can honestly say this is the best overall choice. I have tailbone soreness so I need a special cushion that can provide comfort and support without causing pain when sitting for longer periods like in a flight or at a concert. This was the only cushion that did a great job. It’s also much lighter and softer. Other cushions are typically harder and are uncomfortable when sitting for longer periods.
I recently visited the Nishikawa showroom in Tokyo and I can say it’s a beautiful store. They have Ohtani’s bedroom setup you can try. Their mattresses and pillows are also amazing not to mention their towels and blankets. I hope we can buy them here in the states someday!?
Suggestions:
1. Create a cushion specifically for tailbone soreness. slightly thicker with a cut out area for the tailbone.
2. Create a cushion specifically for wheelchairs and long term/constant seating. Thicker cushion that maintains its shape. Good support with possibly some curvature. Plus a thin cushion for the back seat.
My mother is currently using the Nishikawa double seat cushion in her wheelchair and loves it :)
