Air inflation is not adjustable... if it was, it would be awesome.
The pump and needle that provided don't work. I have tried several times to adjust the level of air in the disc, but it doesn't work. I guess I'll just have to use it until it is completely deflated.<br /><br />I'm an adult woman that intended to use it for mobility while sitting in my office chair as directed by my chiropractor. Not bad for the money, but I doubt it's going to last much longer and I've only had it since 3/14/2016.<br /><br />Spend the extra few bucks and get something else instead.
