Yes. You have to blow them up with the pump. Less air would make them more soft.

Would these work well as pinata fillers (deflated or inflated)?

The knobby balls are ok to use as a pinata filler if the pinata is large enough and if the balls are deflated.

Can I use this as support for my back for massages? Is it strong enough or will my body weight brake it? Thanks!

I had a set simpler to these, without spikes, that came with an exercise book. They needed to be re-inflated occasionally and eventually became misshapen. If I could find it again I would purchase them. They were wonderful counter pressure to use when I stretched. I can see how they would work in massage therapy. I weighed 140 lbs at the time and had no trouble with them breaking. Tennis balls also work but are much firmer to press against. Good luck!
