MerrithewStability Ball Base blue, Medium

It's ok it serves its purpose.Kind of on the high priced side though.

Fonctionne très bien avec des ballons, 55 cm, 65 cm, mais instable avec un ballon de 75 cm.

This item is over-priced for what you get in my opinion. It is cheap plastic with no bottom. As such the base easily slips all over the place. It also may scratch hardwood floors. I put a small rug under it to stop the slipping and protect the floor. It comes in four sections that are easy to assemble but the joins are not perfectly flush. In my view this is worth about $10 bucks, not the $27 charged. The other $20 can be spent on a rubber mat that really should be included. Also, I had to reduce the size of the exercise ball to stop it from rolling over the edges of the base that should have stopped the ball. The base needs to be wider with taller walls to keep the ball in place. If grandma was sitting on a ball too big thinking she is safe she might go flying off the ball. Probably will return it.

Fast delivery cheap price and good plastic and snaps together easy as pie!

Product is simple and has a job to hold your trading ball in place, it does just that.
