BalanceFrom Anti-Burst and Slip Resistant Exercise Ball Yoga Ball Fitness Ball Birthing Ball with Quick Pump, 2,000-Pound Capacity

I’m 5’7 and want to use this as a birthing ball i’m not sure if i should get an xl or a l! what’s the difference in birthing and exercising sizes?

why is the measurement tape so huge? I bought the second largest size and it's impossible to blow it up per the silly measurement tape. inflated std

Does this product contain any pvc? if so, is it 16p free?

Would this ball hold up outside during cold winter months?
