Sructure in steel wire with anti-rust treatment. Seat and back in polyethylene strips with 8mm in diameter. This product was made with materials proven to be resistant to climatic elements, such as teak, acacia, synthetic straw, spray-painted metals, waterproofed fabrics and special mixes of cement, concrete and clay. With the exposure to these elements, changes in color, texture and even small fractures are still expected, commonly valued as an elegant patina. To try to preserve the original appearance of this product, we suggest the use of protective covers and to store it during the Winter.
