How far do the little bumps around the circumference of the ball protrude? Are they annoying when come in contact with body?

Barely anything at all. They're more like a texture than actual bumps. I certainly don't feel them through my pants, and after a few months they've become flush with the rest of the ball anyway through friction from being rolled around and sat on.

I do not believe the size is on the ball but I would say it's a small ball. The smallest of the three choices when buying an exercise ball.

Well this is the first one I have owned, but the ball is smooth and shiny...hope that helps!

Not much. These balls are slippery and way too hard to be effective. I regret buying them. Don't waste your money. Buy Yoga Tune Up balls instead.

Try using some plumbing silicone grease to lube the ball so it roll smooth down

I have an 18 lb ball from a different brand & it is around 1- 1/2 times the size of my 8 lb Valeo ball. I'd say add an inch to the circumference for a couple more pounds added. I hope this helps. I do like the Valeo brand over all others. Very nice grip.

A 2 inch bump is no problem at all have not had any problems on normal bumpsd ans curbs...approaching 3 inches could cause a problem but usually not. This is a great scooter for the cost and works real good in most situations.

I would say they are a little bigger than the tee balls. They are about the size of a softball.

The diameter of the ball is about the same as a tennis ball...maybe a tad bit smaller. The balls are not hollow, they are solid rubber. Just want to say that these work so well for me, my husband, and our children that I bought two more for other family members! They have been so helpful!

No I have not had any problems with bumps. The mattress is very comfortable.

They are much larger than a tennis ball. Probably close to the size of a basketball.

Yes, it all depends on your level of comfort. I'm a smaller person and the gold ball is sometimes too big. I like the silver ball to get deeper into the lower abdominal organs

This particular one is more tennis ball sized. The total circumference is probably 8 inches.

I dont know where you got this information, but who ever provided it is crazy. The round ball is about 2 1/4 inches diameter. It is always fully inflated and bounces very high.

The ball is about 2 and 1/4 inches in diameter. It bounces higher than any ball you have seen. As others stated by others, it was used for most all the games we played as a kid.
