If you have a few unnecessary foam blocks and wooden beams lying around in your country house, you can make a simple bench that is suitable for a veranda, covered arbor or even for a street. For the stability of the foam blocks it is better to cement each other with cement, and somehow unbend the bars, so that they hold tight and do not "walk" through the hole of the block. On the bars it is enough to put some thin mattress and the bench is ready. It is possible and slightly modify the design, puttingover boards of a board and having covered them with a cloth with a substrate made of foam rubber or other filler. But if there are boards, it is better, probably, still make a full-fledged bench with a backrest and armrests.
