So mine popped unexpectedly and it was not even on a seam. It was not over inflated, and I am under the weight limit. I was only sitting on it. 55

That sounds truly strange as these balls are very sturdy. Is it possible it was defective in some way? I did, however, purchase a bigger ball. So far, it has held up pretty well. Check how long you've had it to see if it is still covered under their warranty, and let Gaiam know about your experience.

Sorry, but I tried without luck, my weight is 207 # and always I sit on it you feel the drop of 1~2"

I'm not going to be any help with that question, sorry. I can't find a tape measure to save my life. My son inflated it using the shop vac. It looks to me to be a bit underinflated. Sorry again.

I really can't answer that because I had to send it back. It had a leak right on the seam, so it wouldn't hold the air.

My family has 3 of them, our weights range between 130 & 200lbs. Daily sitting for 1+yrs. with no problem, so the "collapsing" experienced by some reviewers seems to be some intermittent, earlier version issue. I don't see a way to re-inflate it, so my advice is to contact the company for a replacement, as they stand behind the product.

I am in the same boat. Mine came a bit inflated but not enough to use. Trying to inflate with pump (not provided) I don't feel much progress is happening.

It is inflated but you always wont to put air in it for your preference of firmness. Have fun throwing the pigskin!!!!

That's not normal. I just went and pressed firmly down on mine (more than 15lbs would do) and it held its position.

No... It popped like an exploded balloon while it expanding... Maybe I did something wrong during the screw on process??? I just can't say... Only know I won't buy another tho...

We purchased two and we were surprised that they were compressed into a rather slender box, but once we unwrapped them and let them re-inflate, they were exactly as they had been described on the site. We have used ours many times and they actually are quite comfortable. If after 24 hours they are not 4" in all areas, I would suggest that you contact the company and request a replacement.

The pneumatic tube could be blown, but highly unlikely. Try rising yourself so the chair will rise to meet you. It will not rise you off the bottom by itself. Other than that, I have no suggestion.

I weigh 170 ib and it can barely spring back when I tried using it! I'm looking to sell mine after a single use.

I have the 75cm ball. I've done chest presses on it with 70lbs... (I weigh 190. important to follow the directions when inflating it. don't over-inflate. My mom uses the 65cm she prob weighs 150ish. She uses it as a chair. I think you would have to do something stupid to pop it....lol they have a video on youtube with a pressure test of 3, 000lbs.

dont know i didnt keep it long enough to have anything tested on it. i returned it because it wouldnt stay inflated. you might want to contact the vendor and get more info. the amazon rep that i spoke with said that it depends on the room temperature. sorry i couldnt be more help. good luck!

That has not been our experience at all. the mattress has kept its form nicely so far these 3 months. It gives a bit to conform to you, but it hasn't sunk at all for us. I'm a semi-normal 190 lb male and it holds me fine. If I were double that size, I suppose it might sink a bit.....

Regrettably I am over 130 lbs. -- more like 170 -- and my weight as such did not make the mattress a "bad sleep." One can wake in the middle of the night and realize one is in a bit of a hole, but after rolling up out of it, the hole disappears immediately.

My air tube popped out easy to blow it up. I use the air mattress pump now much easier and that might work if yours is defective. Or send it back.
