My sister-in-law had these chairs in the 1960s. They were part of the "Mediterranean" style popular at the time...so if they were up in the attic for more than 50 years, they were practically brand new when they were put up there ;-).

Here's a link to a similar chair that sold on Etsy. There is a link to contact the shop owner--you might be able to find out the age or value.

"Mediterranean" was very popular in the 60. Not an antique, yet , however. It's pretty cute; I wouldn't hesitate to clean it up/refinish it. It looks like it had some use before it was put into the attic. I'd reupholster it in an updated fabric and have fun using it.

I purchased a pair of these chairs at an auction for a dollar each. Mine were in dire need of refinishing and reupholstering. I have not been able to find out any info on them but believe they are from the 60s.

I have 2 of these. Cool looking chairs. I’m trying to find out if they’re antique

Did you read all the posts above? Not antique.
