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

I’m currently using it and i love the quality!

Product is poorly made and leaked on first inflation. When I sent a notice to Trideer they responded “ Sorry for having left you an unpleasant experience. Please believe that we will continue to improve quality and strengthen quality control in the future.” Terrible **UPDATE** Manufacturer came back with an offer to fullly replace the product. I’ll keep you posted. Roll on. **FINAL** OEM made good and replaced the defective unit. They made it right.

First ball wouldn’t hold air whatsoever, i’m now on my second one and so far it’s going well but we’ll see

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.

I am 21 weeks pregnant and have SPD, I haven’t been using the ball long enough to see any lasting relief, but it is much more comfortable to sit on that any chair. I am 5’7” and my desk is 30” so I ordered the 65” ball and it is definitely too short. It is holding the inflation fine and I inflated the day before as instructed, but it seems the ball at its full inflation is not the correct height for me - will probably need the bigger size.

Too small

We purchased this to replace a ball from the same company that popped. However, dont let that deter you. These are very sturdy balls. That ball lasted through several years of my daughter sitting and bouncing on it daily. She uses this to sit at her desk and do schoolwork, and for exercise. The foot pump works well to inflate it. Also, I am very pleased to report that the safety feature works well that prevents it from deflating quickly in the event that one does pop. This is a useful, quality product!

Im a big fan of Trideer stability balls because theyre so thick and supportive. I had a herniated disc in my lower back that no other method was able to address. I ordered a L ball that fixed my back when I arched my back across it. I reordered this ball after years of using the other one. Unfortunately this one was the S size, even though my order says I ordered a L. If I had checked it in time, I could have exchanged it for the right size. But I was delayed in checking it and missed the window of time. However, it is definitely a nice, thick, high quality ball.

This works great!

I sit most of my day at a desk and my desk. My back has been bothering me, so I thought I’d try using a stability ball. So far it seems to be marking a difference.
