Trideer Extra Thick Yoga Ball Exercise Ball, 5 Sizes Ball Chair, Heavy Duty Swiss Ball for Balance, Stability, Pregnancy, Physical Therapy, Quick Pump Included

The tape measure and the plug remover were missing from the package. Once we were able to figure out how much air it needed It works well.

Easy to inflate and deflate, very nice exercise ball.

Easy to blow up, good quality, good purchase.

Definitely inflate the ball once and again after 24 hours. It is great I exercise with it often

This works great!

Very nice and rubbery feeling with this ball Love it as my grandchildren are doing a lot of things with it. As a exercise ball I am sure it is very good

We got a size L. It seems to be a tad big for my 6 year old... but she loves to body slam and throw her body around. This ball has been amazing. After bouncing, rolling, jumping and hitting it, rolling it over herself... just all kinds of manipulation. She paused, and sighed, mom, I LOVE this ball. A few moments later she was just laying over it and deep breathing like meditative deep breaths. So calm.... not sure I have ever seen her that deeply calm and happy. :D If you have a child on the spectrum or with some sensory difficulties. This was wonderful for us. My body appreciates the reprieve from those unconciously made body slam hugs. (XL would have been to big. L is ok. M may have been better though.... but L will do just fine. Her feet do not touch the ground when sitting... which allows her to use other parts of her body to balance. Which may be another win in itself.)

Nice size. I’m using it for yoga and balance. I’m 76 so I have to watch out for my bones.

Using product for sit-ups and back stretches.

Sturdy, large and would recommend.
