Extension carts reduce a set of unnecessary behaviors which include move loads, place plates on the ground and put the loads down.
In addition, considering the problem of long-time uncomfortable sit-in, the cart provides a comfortable environment. When you pull out the plates, the space for the goods increases, and you pull the handle back, you can sit on the handle. So users feel convinced when using cart, just by the simple functions of the cart.
