One problem faced by people during moving is how to move large pieces of furniture, i.e. sofa, mattress, table, refrigerator, etc., conveniently without damaging them. A typical small dolly is incapable of carrying such large pieces, and a bulky dolly is inappropriate for an indoor use because it can damage the furniture and the floor. Besides, in either case, the user should lift up and put the load on the dolly. People who want to change positions of their furniture regularly to get a fresh look for the house, it is cumbersome to call a moving company every time. Our team aims to design a dolly system that can load large pieces of furniture onto adjustable frames with multiple wheels so that the user can tow or push furniture without hassle. The lift function of the dolly can jack up the furniture by pushing up the bottom of the furniture. The lift system does not require much power so that most people can easily load furniture onto the system. The frames are extendable for various types of furniture. When not in use, the system can be disassembled and stowed easily.
