I got this as a booster for my daughter’s piano bench. It gives her the height to have her arm at piano level. The cushion is easy to inflate and came with a hand pump. The cushion looks spiky but it was actually pretty comfortable to sit on. I also tried inflating it more and it creates a curvature like half a basketball. My daughter used it as a balancer. It seems pretty durable and was able to handle my daughters weight (~100lbs). Overall a good price for a durable cushion.

The product came folded in the box and lost its original shape. Even after it is full, it is in a damaged format. The pump came broken.

It is easy to use. After it is inflated, it works great for back pain if you put the cushion at the back of seat.

The pump that came with this is broken and the time was unable to be inflated. Very disappointed in this.

It didn’t come ready to use as described. It was folded in half and pushed inside a bag, and then the pump to make it more filled didn’t even work and was broken. Pump puts a hole in the item on the other side when pumping it too. The pump never worked and when I tried it just put hole through no air at all. Overall was excited to get this but I can’t even get it to work as it should and it did not come ready to go.

This takes some getting used to at first but once you've got it it really is comfy and helps my back pain while working at home. I'm a heavy gal and it holds the air just fine. And compared to some others I've seen this one is at a good price for the quality!
