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

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.

*Edit* they sent me the remover. Ball is holding up fine. Be warned the XXL is massive lol Did not receive the plug remover, so after following instructions filling to 80% and then attempting to wait 24-48hrs to fill to 100%, I cannot remove the plug to fill to 100%. The instructions say to use the plug remover, however I just received 3 plugs and no remover. Would be a simple contact to fix, but alas it states there is no service available for this item, and Amazon can only return, refund, or replace. I did not want to wait for all of that, I just wanted a complete order. Also it took me like 1500 foot pumps, you’re probably better of using a bike pump or compressor lol but I just used what came with it.

Physical Therapy - For back pain relief, stretching, sciatica exercises What I didnt like about it is that it when you inflate it and remove the pump to insert the pin it begins to lose air. It does bot have like a non air escape feature to allow you time to insert the pin in the designated hole. 2nd: after three uses it loses air and you have to inflation again. It is stable though, like the color and the texture which makes it non-slippery when grasping.

Easy to inflate and deflate, very nice exercise ball.

Thing is huge. Is what it is.

I bought this for my pregnancy and it helped stretch my hips and back throughout the last few months. Perfect size for my 5’3” frame

I received the exercise ball & it inflated fine. My complaint is I ordered purple, you sent black. To say the least I was disappointed.

Update: I was contacted by customer service to resolve any issues i had with the ball and they were very pleasant to work with. I ended up sticking with a different ball I got at a local retailer but I do appreciate the effort for customer satisfaction!! I bought the large because I wanted something a little bigger like the ones I used at physical therapy. The Large says it is between 58-65cm. As you can see in the picture my ball is maybe 49cm and is relatively uncomfortable to use and I have it filled as full as I can get it. It also doesnt feel very sturdy, Im roughly 200lb and I feel like im going to pop it every time I use it and Im not even putting all my weight on it. Disappointing ball.

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

I have bought this brand in the past and had no problems. I bought to have at my office and I only work 2-3 days a week at the office. The ball does not appear to have a hole or anything. I have my own office and dont know why this has happened. Update: I received a message from Trideer that they will be sending me a new ball. Thank you for the great customer service.
