Here is a cool cart that lets you move heavy objects up and down stairs more conveniently. The UpCart not only lets you move heavy objects around easily, it folds to a depth of over 4 inches for easy storage. It can “walk” over curbs and stairs, decreasing pull/push forces when moving over an irregular terrain.
The UpCart comes with an adjustable handle and distributes the weight of the load evenly to make it easier to handle heavier objects. You can find out more about the product here.
