By setting self-locking pulleys, electric push rods, round hole 1, cylindrical holes, left controller, and right controller, the sofa can be telescoped to meet people's needs for sofas. The sofa can be telescoped and deformed according to personal circumstances. The left controller and right controller can make the sofa automatically telescope. The telescoped sofa can be used as a single bed to meet people's needs for rest or a short nap on the sofa. When there are many guests at home, the sofa can be stretched to provide seats for guests.

[0004] However, in the implementation of related technologies, it is found that the above technical solutions have the following problems: In the process of using the existing sofa furniture in the above device, it is usually of a fixed shape and cannot be deformed or stretched. When people want to rest or take a short nap on the sofa, the length of the sofa cannot meet people's height, resulting in the inability to meet people's need to stretch their bodies to rest. The sofa occupies a large area and plays an important role in carrying the family and guests sitting. When the living room area is too small, a large sofa will make the room look more cramped, while a small sofa cannot carry multiple people. Moreover, for the extended part of the sofa, when the bottom support component is subjected to too much external force, it is prone to collapse. Therefore, further improvement is needed. Content of the Utility Model

[0005] The utility model provides a telescopic and deformable sofa, which solves the problem in related technologies that it is not convenient to maintain the support balance of the extended cushion block.
