It's 15 5/8 inches tall. The seat is like sitting on the hardest Styrofoam. It doesn't feel like a cushion at all. It has a lot of storage for tools, fasteners, parts, etc.. All are removable, so I don't know how long it will last before the two side pieces that just sit in there will start falling out. But one could put all the parts that need to be washed in one side, then take those parts to the washer by just taking the tray with the parts. The seat does also come off and it's lower than my creeper, so I can just put my back on it and get under the lower cars without having to jack them up. But either way it's a very low seat. I'll still use my old one with this one to keep parts separated. There are a lot of trays in it.

Why do I have to put this together?

There was nothing wrong with it, but I just didn't have room for it.

It seems to be decent product but the directions aren’t clear and customer service is horrible. They don’t answer the phone nor return your call.
