Claims. (01. 155-47) This invention relates. to new and useful immovements in folding or knock-down furniture, and more particularly to a bed or cot which can be easily converted into a chair or couch, or vice versa and can be readily knocked down or folded into a compact bundle for storage and transportation.

An important object of the invention is to provide furniture of the above type which has its body supporting part composed simply of a pair of side rails and a body supporting strip or sheet of flexible material stretched between them and secured in a novel manner which also provides for the quick attachment and detachment of detachable supporting legs for storage purposes.

Another object of the invention is to provide novel leg structure for the furniture which can be easily adjusted to tension the supporting strip as desired; it being a further'object to provide legs of such length and proportion that with the two-part type, the legs of the occupant may rest on the ground without discomfort.

A further object of the invention is to provide the bed structure with a component for converting it into a chair with a back which can be held upright or in reclining positions with one relation of said component, or in a further reclining couch-like position by adjusting said component to a different relation to said back.

Another and important object of the invention is to provide one form of the structure with an extra section to provide standard length for the cot to thereby support the lower limbs and feet of a person and to serve as 'a cover or sun shade when the structure is serving as a chair.

Other objects and advantages of the invention will become apparent during the course of the foilowing description.
