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

My initial review was 5 stars: Unlike most buyers here I did not actually buy this for myself. My sons gym teacher recommended this as a tool to help him build up his core strength, which was below average. This ball has already made a huge difference in his ability to balance after a very short time of use. Thus far it has been easier to motivate him to use this as a chair to somewhat passively work on his core, than it has been to get him to practice more active exercises. Since my initial purchase I have purchased more and unfortunately my second ball (purple) for my younger child started deflating by nightfall. It arrived with a slow leak, so although it is usable it is very tedious to constantly refill it every morning.

The Amazon review I left for this ball: I purchased this ball while pregnant and used it as my chair at work for the final three months of pregnancy. It worked well! Once baby was born, I was able to hold him while I sat on the ball and bounce him gently to sleep. It worked well for that, too When the baby grew into a toddler, he loved playing with the large ball, rolling it around the house. It was a hit! Those three things above are enough to get a good review, but the following is why I’m submitting this review! The previously referred to offspring rolled the ball out the door one windy evening, it caught the wind and blew away. We thought never to be seen again. We were wrong. A kindly farm neighbor let us know days after the ball blew away that the ball had been spotted in a waterway that ran through his field. This determined mama set off across two fields full of sharp corn and soybean stocks, across a gravel road, through many briars and thistles, and spiky cut off scrub trees to find a perfectly intact yoga ball waiting in a puddle. This ball not only survived bouncing a mile or so through the afore mentioned hazards, it withstood a lightening and hail rainstorm and later, the intense heat of the sun. So, while I don’t recommend purchasers repeat the unintentional experiment we put this ball through, I can with confidence say, this is a durable yoga ball.

This is the 3rd exercise ball Ive ordered off of Amazon and this one finally ALMOST reached the advertised height. I read the instructions and filled the ball to 80% filled and waited two days before I added more air. Other balls dont come with instructions to do this or any instructions at all. For most of the filling I used an electric mattress pump, but once you get to that 80% it seems like the ball just wont go any bigger. I ended up using the foot pump it came with to keep pumping air into it while measuring the height every couple minutes, but Im 8 months pregnant, so using the thing was exhausting. With the included pump I was finally able to get the ball to about 60cm, which got my pelvis in the right place and got my legs to a right angle like they should be. The ball feels super full with very little give, and even though Ive only used it for a week, it feels very stable.

Love this ball, new addition to home gym. I am 6mo pregnant and will be using this often. Great price, overall very happy with purchase!

The ball deflates to about 85% full from 90% full pretty quickly. But easy to use and does the job, maybe too well.

This is a great exercise ball. Inflating it wasn’t bad, just a little time consuming. Don’t lean this up against a finished wall. When I moved the ball away from the wall, it took the finish paint right off! Left a mark on my wall and there is now paint finish stuck to the ball.

I bought this to rotate with my desk chair for better posture and ended up using it as such and in my workouts! All around, excellent ball. The material is thick so it can hold some weight (Im 51, 150lbs). It is also high enough to function well as a desk chair - picture to show the height equivalent to my standard desk chair. There are no shortage of options for using in your workout routine either! No regrets with this purchase :)
