It is cheap plastic garbage

is a nice solid matte, not the cheap plastic stuff that you find in the lower-end exercise balls (see the gray ball

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

The useless plastic sack I received seems to be decent quality.

There is a strong plastic smell when you first take the ball

I've had different ones that are more of a hard plastic or a slippery material, which I didn't like, so I gave this one a shot

L was just right for me to sit on

So disappointed as I don’t have a way to inflate it.

n’t having trouble with pumping the ball with air

n’t know why it leaks air

n’t had as many issues with neck and back pain since I started using the ball instead of normal desk chair.

n’t vouch for the one it comes with

n’t work at all

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