i do have to keep inflating it a lot which is hard because the piece that keeps the air in is very hard to take out

there was no loose pieces or anything in my

I will happily update this review when the missing pieces arrive

It was my favorite piece of equipment at the Livestrong program at the YMCA

Trideer wasted no time replying and within a week I had the missing pieces

The plastic pieces to close the ball up after inflating were missing

You are provided a cheap plastic pump (for hand or foot), and the hoses that attach the pump to the ball's valve are incredibly cheap pieces of plastic that refuse stay together during the process

Disappointing as I was really looking forward to using this as my work-from-home office chair.
