This is a piece of furniture that combines the functions of a sofa and a bed. On a daily basis, it presents itself in the form of a sofa, featuring comfortable cushions and backrests, and can be used for daily rest, receiving guests, etc. Its appearance design is diverse, with rich colours and patterns, and it can be matched with various home styles. When there is a guest staying overnight or a temporary rest is needed, simply by performing simple operations such as pulling out the folding latch or pulling out the sliding slot, it can be transformed into a bed, providing a sleeping space for people. It has various materials, with the cushions and backrests mostly using nylon straps and cross-net structures with snake springs, and layered with high-elastic foam, etc. The bed cover fabric is usually made of fabric, thick and durable. It doesn't take up much space and is easy to move, making it a very practical multi-functional furniture, especially suitable for small-sized living rooms or families that need to entertain guests frequently.
