Title: Non-inflatable beach mattress device which is edged by a rigid frame and can be converted into a seat
IPC: A47C9/10
Filed: 1986-02-04
Abstract: The present invention relates to a non-inflatable beach mattress, intended for placing in direct contact with the ground, characterised in that it is edged with a peripheral frame, consisting of rigid elements which are articulated to one another and are fastened to the frame.

This appliance can be folded and unfolded very rapidly so as to have only a reduced bulk during transport and storing. Its simple design and low weight enable it to be carried on the shoulder, acting then as a beach bag. This invention, the multiple capabilities of which should be sufficient to promote it, should represent an important market as it constitutes an intermediate solution between the straightforward conventional beach mattress and the sophisticated and bulky seats.
