I will say that I received this as a Christmas gift a few years back and It has been great. I did spray lube the hinges and lever. Its comfortable and surprisingly easy to move around.
The Bone creeper and Tail Bone chairs. 100% made in the USA. I made my creeper and chair in high school welding class. Otherwise, this is the brand i would have gotten.
Big wheels if you work in your driveway. I got a Jeepers Creeper.
My driveway has a slight slant the the Bone Creeper would slide down into the bushes. It rolled too freely.
Now think about that as a complaint. It rolled to freely. LOL
