Trideer Exercise Ball (45-85cm) Extra Thick Yoga Ball Chair, Anti-Burst Heavy Duty Stability Ball Supports 2200lbs, Birthing Ball with Quick Pump (Office & Home & Gym)

I ordered this to help me get more aligned and ready my pelvis for my FIRST birth. I got this May 24 and on the box it said to inflate half way and wait til the next day to inflate the rest and use.. of course I think okay well I have time!! My son isn't due until June 4th no rush to use it.. well May25th I finally get to use it and it was great support and it was durable! I was worried it was going to be weak and not support my wieght (220 pounds pregnant) (alot yes I know for such a tiny frame) well I get to use the Ball to not only help with my siatica but also get my hips to get a break ... After about an hour later I get on the ball to do my exercises.. and then Burst!!! My water broke !!! I love this ball and I was so glad because I was done being pregnant and For moms who want a good birthing ball but don't want to spend 100$ on a birthing ball kit this is it!!

The 55cm exercise ball does not hold air for more then a few hours no visible damage and can not find any leaks even after trying another plug that was included it still losses air. Since it is now November and roughly a month past purchase date it is no longer returnable to Amazon I tried to reach the company Trideer since it says it has a one year warranty but their email address comes back saying it doesn't exist. Save your money and buy from another company

I would say this ball is “fine”. It seems like it’s hard to keep it fully inflated. I can pump it up fully but after a few days it starts to get squishy. It is acceptable for what I use it for though (I am 110# and mostly do not put my whole weight on it). I probably wouldn’t get this if you want to use it like a chair. It would probably be annoying to reinflate constantly.

This ball rocks. The foot pump sucks but I have an electric pump so that was much faster and less work. Using for a birth ball and followed the size chart. Recieved the correct size. Seems very durable and happy with my purchase!

It is a good product for what it is. It doesn't inflate to the size that it says it is supposed to. Holds air well.

This broke within 2 months of owning it. I’ve had other balls last for years. The size on this is small as well. Would not buy again

It was just as I expected, I use it to exercise and stability.

Wasn’t aware this would be a used/returned item. Packaging was completely torn up and still had the previous buyers information on the shipping label. Throwing it into another box and putting my information on it doesn’t make it new. Buyer beware.

Came with no plug for inserting into after it has been inflated. Contact seller and they me correct plug immediately. The ball great , very good for pregnancy yoga and general core fitness work. worth paying a bit extra for a quality ball. I would advise to go for no smaller size than 65cm if you are over 5'6 based on our experience.

Brilliant all round! Arrived ahead of time. Right colour. Quite heavy (good quality) My wife's favourite colour. Well in time for Xmas

Ball needs pumping up periodically, but it does the job.

Muy buena. Es para hacer un regalo y usada como silla. No se ha deshinchado y lleva 45 dias usandose 8 horas diarias. Para repetir

Perfetta anche se sottile come spessore gomma e da rigonfiare ogni tanto. Utile a casa per piccoli esercizi posturali ...
