Folding bed

Abstract

The invention relates to a folding bed, belonging to the field of furniture, comprising a mattress, a pillow and a bed frame. Seven X-shaped support frames are adopted to constitute a main structure of the bed frame, and an upper edge of the X-shaped support frame is provided with foldable support rods and connecting pieces. The whole structure may be folded longitudinally and transversely to form a columnar body after folding, which can sufficiently reduce the gap between the support rods, so as to minimize the volume, and it is convenient to carry and store after use. The pillow is filled with memory cotton to fit the human body and is comfortable for sleeping.
