Brutalist chair from the 50s

Interesting chair from the 1950s and 1960s, the designer of which remains to be identified. Charlotte Perriand mountain chalet style, in a brutalist, minimalist style, with an oversized, straw-covered structure, it features a very low backrest for a very original look. The straw is in excellent condition; the wood has warped and cracked in places, making its strength questionable given the available sections: -) Height 65 cm. Width 45 cm. Depth 35 cm. Seat at 45 cm (classic).
