The living room is a place for families to maintain their relationship. It is a place for the elderly, adults, and children to take the rest and even for fun. We attempt to change living room space as a full-age use place and a place to make the most effective storage. We designed a multifunction chair to make the living room become much more convenient. By using tile chairs we can store multiple tile chairs on the wall, and when there are many visitors, the chairs can be easily removed from the wall for use. At the same time, the chairs on the wall are also for the children's college game, and the sensor light on the side can provide a lighting system for the elderly when they are walking in the dark. This design not only reduces the trouble of chair storage, but also provides a livable lifestyle for all ages in the family, and achieves beautiful and interesting effects.
