Trideer Exercise & Yoga Ball - 5 Sizes, Pregnancy & Maternity, Anti-Burst, Heavy Duty, Office Chair Ball & Gym Ball with Quick Pump

Pump and attachment in box make inflating easy. Seems good quality. Great value.

Great ball, 3 years later still in the good shape and they were very kind to send for free the plug replacement.Would recommend

Good enough size and seems sturdy enough currently being used by me 29 week pregnant partner and holds up pretty well.Doesn’t hold air for as long as you’d think and the pump is borderline useless but it’s cheap enough so can’t really complain.

A thicker material for the ball than others. Is excellent for regulation for my son. Hopefully it lasts a lot longer than the other brand that burst on day one

Bought this to start using towards the end of my 2nd trimester just to sit and bounce on gently to relieve some pressure. I got size large and I’m 4’11 I would say it’s the perfect size for me. I followed instructions and inflated by 80% left for 24hrs then inflated completely then waited another 24hrs, I believe this is important if you want it to last and to be safe, those who said it burst straight away have probably not followed the instructions. For the price it is brilliant considering it will get over 10 weeks use from me and then I can store it up in the loft if I ever fall pregnant again. Recommended to pregnant ladies suffering with PGP, sciatica and round ligament pain.

Great ball but returned as I ordered too small for my height. Very robust, easy to inflate (and deflate!!) Will be buying the bigger size!

Very good quality, the measuring information was spot on. Excellent value.

The ball itself is fine, like the ones I've used in the gym which I presume are higher quality and more burst proof. It needed more like 3-4 inflations / top ups rather than 2, to achieve final firmness. I was a bit dubious because it was more egg shaped than spherical but in the end I think it got there.The problem was that - unless I was sent the wrong one, but I don't think I was because the number 75 was in the product code on the box - there was no way that my supposedly 75cm ball was actually 75cm in diameter! I put a box 75cm away from a wall and rolled the ball through it. I carried it through my doorway which is 76cm wide. It was only 65cm in diameter. To have made it 75cm would require a lot of extra pumping, and I really don't think the ball would take it!Amazon processed it as a free return because they weren't the ultimate seller and couldn't tell me if e.g. the 85cm ball would be 75cm when inflated - or even if I was really sent the 75cm ball.
