I am a car seat tech, and I was assisting a client with the Cyber Callisto G360 Sense US. When rotating the seat incline I placed my righht hand on an open space on the back of the seat where a hand would obviously go, just under the sun canopy. With left hand at the feet where a similar pocket exists, with a push in spot- I turned the seat up to move incline. As I did that my right hand specifically ring finger and pinkie, got jammed in that open space as the reclining seat basically cut my fingers/jammed them in that hole area I had my righ hand. My ring finger at the nail was cut, and my pinkie has a blond blister under the nail. It's quite painful and more so when pressure even of typing these words. Sadly, when the mom was attempting to move the seat incline- she did the exact same thing, despite my injury happening in her presence, and me pointing out how it happened. That pocket space that seems perfect for right hand as left hand is below. The mom smashed and cut her fingers also. This design is dangerous to any user.
