This U-shaped sofa bed seamlessly combines daily relaxation, temporary accommodation and home storage. It is suitable for small-sized living rooms, audio-visual rooms or multi-functional rooms. The sofa fabric is made of chenille. This fabric has a soft touch like short fibres, with fine tufts on the surface, presenting a gentle and restrained appearance. It also has good wear resistance and anti-torn properties. The filling of the seat and backrest is high-density foam, providing a firm and elastic sitting experience that evenly distributes body pressure and is not likely to collapse or deform over time. The movable chaise lounge can be freely placed on the left or right side of the room according to the room layout, thus achieving a more flexible placement scheme. The middle loveseat has a pull-out bed function. When needed, it can be converted into a bed by pulling the strap and using the convenient rollers, providing a sleeping space for guests staying overnight. When retracted, it does not occupy any additional floor space, maintaining the cleanliness of the sofa appearance. The loveseat on the side integrates comfort and storage. The seat can be lifted upwards, revealing a spacious storage compartment underneath, which can store blankets, pillows, seasonal clothing or miscellaneous items. The seat of the empress recliner is designed to be lifted upwards, revealing a large-capacity storage compartment as wide as the seat, suitable for storing infrequently used large items such as bedding, cushions or children's toys. The interior is equipped with metal hydraulic rods and a strap. Two square armrests are designed with storage boxes below, making it convenient to store remote controls, charging cables, headphones and other scattered small items. The armrests integrate cup holders and USB charging ports, allowing for immediate power supply to mobile phones, tablets and other devices, eliminating the need to search for an outlet when getting up.
