BalanceFrom Anti-Burst and Slip Resistant Exercise Ball Yoga Ball Fitness Ball Birthing Ball with Quick Pump, 2,000-Pound Capacity

55 cm is great height for 5' - 5'7 (for sitting). Purchased as desk chair replacement, and it has helped my back and hamstring tightness (from sitting too long)!**I recommend the bigger sizes for taller persons or sitting at taller tables.**Required 2-3 inflations over 2 days to reach full size.**Great quality for discounted price (36 AED).

The exercise ball comes with a manual pump with different sized nozzles that can be used to fill it up. Before being inflated there may be a few creases and dents on the ball, which smooth out well once inflated completely. A automatic ballon inflator can also used

GOOD

I got this ball for my pregnancy. I’ve been using it for about 4 months now almost every day and it’s still as good as new. The size is also as expected and the purple color is pretty.

I just received this today and tried it right away, all i can say is.. Very very helpful! 🥰 I'm 36 weeks preggy and sitting in any chair seriously hurts my back! So when i tried this ball.. I don't feel any pain at my back. This is going to be may chair for the rest of my pregnancy 😁

Ball is of good quality.. came with 2 year warranty card. The packaging was good it came along with the foot pump , measuring tape !

The ball came with a portable air pump which was a surprise. The material of the ball feels durable and can last for a long time. Overall, I’m happy with the price and quality of the product.

Good product but had to inflate manually. Pump was ridiculous.

It’s a shame because it’s a good quality ball but I’m 5ft and went with the 55cm ball, and I am so uncomfortable on it. I feel like my air supply is cut off when sitting on the ball and my hips aren’t higher than my knees which causes a lot of pressure on my lower stomach due to my thighs pushing against my belly. I’m really disappointed. The sizing chart says for Birthing it’s 5ft & under is Medium, 5ft to 5’5 is Large but I think I would get myself an XL despite being 5ft! I would return the ball but I already threw out the bags everything came in. DO YOUR RESEARCH on sizing before purchasing & don’t go based off their sizing chart.

With the price being lower than others you sometimes question the quality. However were actually very impressed. The included foot pump made inflating the ball easy, it only took about 10 minutes to fully inflate. There is a tape measure to help you know when to stop inflating and spare plugs in case you loose or damage one.The ball is supportive but squashes nicely if you sit on it. Its proving very helpful for my wife as this was mainly purchased to assist in her pregnancy. Appreciate the sizing guide for Birthing use meaning you get a larger size than normal.The color is slightly different than pictured its a little less dark purple, but for me this made it better.Overall very happy indeed!

I like that it was really easy to inflate, and it felt fairly sturdy. Unfortunately, though, it broke just 4½ months after I got it. It was a surprisingly gently burst, at least; I was sitting on it at the time and it felt more like being let down to the floor than fully falling. Another thing is that when it came it was a bit slimy (in a rubbery/factory way) but that was easy enough to clean off after partially inflating it. I would have rated it 5 stars overall if it hadn't broken, but because of the short life span I've had to drop it down. It does say two year warranty, though, so I'll update this after I've contacted their support.Update: I contacted their support and they told me that they can't help me since I don't live in the united states. When I mentioned that Amazon doesn't offer support for this product, they asked me to provide an American shipping address (which I don't have). So, my experience with this product is that it's a pretty decent exercise ball for a few months and then after that it's a nigh-useless piece of rubber.Update 2: I ordered a new one and managed to return the old one, and it's been going strong since. Would recommend if you're okay with some risk.

La pelota llegó en tiempo y forma. Es exactamente del color que se muestra en la imagen. La mía es mediana. Es muy facil de inflar con la bombita que trae. Además, trae una cinta para medir el diámetro indicado para inflarla. La estoy usando de silla para el escritorio y está perfecta. Mucho más económica que en el mercado y de excelente calidad. Tal vez compre otra para mi esposo. Muy recomendada.

I purchased this ball and tried to inflate it, but the pump broke. I contacted the manufacturer, both by email and phone, and no reply was provided. I will correct this review if I hear back from them and they solve the issue.UPDATE (Oct 17, 2020): The company wrote back to me and told me they could replace the pump at no charge IF I reside within the US. That means that their 2 years warranty is not valid if you live in Canada, which is not indicated anywhere. Also, I am not that satisfied. The ball needs to be inflated every week...
