KEYUCA High Rebound Round Molded Cushion 40cm - Sold Out. This is one of the cushions I looked for to relieve back strain during desk work. I found another cushion that suits me better, so I'm selling this one while it's still new. It's high-rebound and designed to reduce fatigue even after long hours of use, with excellent pressure distribution. The cover has been cleaned. ■Size: Diameter 40cm x Thickness 4cm #KEYUCA #HighReboundCushion #RoundCushion
