An adjustable sofa-bed assembly for use within a vehicle such as a van or RV. The sofa-bed includes a seat portion, a back portion, and either a permanently fixed base or a removable leg portion which allows the legs to be installed into the vehicle prior to installing the seat and back portions to allow for additional elements to be installed beneath the sofa-bed, such as power elements for a powered sofa-bed assembly or for other equipment. The sofa-bed can be transformed from a sofa configuration with an upright back portion to a bed configuration with a laid-flat back portion. When in the bed configuration, the seat portion and back portion are aligned such that there is no gap between the two portions and the two portions lie completely flat, forming a complete bed assembly.

The present invention relates to a seat frame, including a lower base; an upper base; and a plurality of rotating devices disposed on the upper base or the lower base and including at least one rotating device capable of horizontally rotating the lower base relative to the upper base. The lower base is connected to the upper base. When the rotating devices make the lower base horizontally rotate relative to the upper base, the upper base and the lower base do not fall off each other. A plurality of connecting devices are disposed on the upper base. The present invention eliminates the noise generated in the rotating process; and a telescopic support enables the size of the seat frame to be adjustable, the installation is simple and convenient, the use effect is good, and it is more stable and is suitable for popularization.
