Ball does not reach optimum size . Used it for 10 weeks . Company needs to replace this

I got this to help with the pressure of pregnancy (as advised by both my physical therapist and OB) and add flexible labor positioning options (per my doula). I had a well-known, more expensive brand 2 pregnancies ago, and this one matches the quality. If you stick your face right on it, you can smell a slight manufacturing scent, but i distinctly remember that with my previous expensive one, as well, so I'm pretty sure its just how the material and manufacuring process is with these things. You can't smell it (even with sensitive pregnancy nose--thanks, HG!) when just sitting on it. Also, after having it around for a few weeks, the scent is fading.Definitely blow it up, let it sit for a few days, use it some, and blow it up a bit more. Yoga ball material stretches some at first, and you don't want a slouchy ball. It holds air perfect, though...this is just a normal breaking-in period "issue" that all yoga balls have.Pumping it up takes a little while. My previous ball's pump worked better, pumping the expensive brand ball in a matter of 2 minutes or less. This pump functions the same way as that pump (pumps air OUT regardless of whether you're compressing or extending the pump), but it's just not as efficient. I was still able to pump it up in less than 5 mins, though. So, if youre looking to bring your own ball to the hospital, you can certainly deflate it and re-pump it (or, rather, have your partner or doula do that for you!) when you get to your room.Since it works well for pregnancy sitting, it'd also be great for flexible office or school sitting. It's also the right material to be stable and not slippery for actual yoga.

First ball received did not hold air. Contacted service dept., had a email response within hours, and replacement ball sent the following day. Ball is very solid, holds air well. Great product, even better service.

I bought this to replace the ball in a Gaiam medicine ball desk chair I have used for 5 years or so. It fit perfectly and so far (over 6 months), I haven't had any issues with it losing air or anything. It's comfortable and seems solid in its construction.

I have had this ball for a couple years and I think it is so incredibly high-quality. It is thick and very easy to deflate in reflate. Reflating it takes around 15 minutes with a little foot pedal, but I only have to do it when I am moving and need to transport the ball flat, otherwise it doesn’t lose air.I originally ordered this ball to do back exercises on after a surgery, but I have branched out and now this ball acts as my office computer chair.The pack is great and comes with extra pens a tool to scoop the pin out the pump and a measuring tape. My only complaint is that the ball doesn’t say what the size should be on it (ex. 45-80cm) And since I ordered it a while ago, I can’t remember exactly how much to inflate it. I just started inflating it till it was a good height for my desk.

I used this ball during my pregnancy and afterward to sit on and bounce while putting baby to sleep.My husband also uses it to help stretch his lower back.I haven’t had to add more air since I initially inflated it. It’s been a year now and it’s holding up great! Love it! Would definitely purchase again.
