Wow! The modern style of these Lane Alta Vista dining chairs is fantastic! They are marked on the underside with style number 493/72 and serial number 476060 which dates them to June 6, 1974. However, I have yet to determine the collection name. I love their bold wood frames with the slight curve to the back. They could border on being a Brutalist design. All retain their original striped fabric of varying widths in colors of oatmeal, black, brown, and orange. It is in wonderful condition and could be used if it suits you. Their tall backs have a four-button detail, as do their seats, which adds to their mid-century modern tailored style. I’m sure you will love these as we do. Make them yours.
