Query: great helper for moving furniture!

I recently rearranged my son's room. With this little helper, I was able to try a dozen of different arrangements in a short time with ease. It can be used on floor and carpet. even my son can push his chest on the carpet. A must have in a house!To use on wood floor, it is better to slip on a used sock, and it won't scratch the floor.
