Abstract: A folding lounger with a frame having parallel longitudinal elements each of which is provided with two hinges defining a central portion forming the seat to which are hinged folding legs. The frame also has an upper portion and a lower portion each of which includes a fabric stretched between the two longitudinal elements, as well as at least two supporting crossbars arranged one at each end of the frame. The folding legs are mounted at each end of the seat on joints fastened to the respective hinges the joints being provided so that the folded legs can be juxtaposed in pairs. Support bars are provided with a joint so they can lie alongside the longitudinal elements to allow them to be brought together on folding, whereby the fabric becomes slack and lies outside the structure to avoid being damaged when the lounger is fully folded. The lounger further comprises locking devices for locking and stabilizing the chair when it is fully unfolded and ready for use.
