The first two pictures, below, are from a 1948 advertisement for Daystrom dinette sets. I love these vintage chrome-legged tables and chairs. (My own set was made by Douglas).
But we also have a Daystrom set, seen below in this photo that was taken in our sunroom in 1978 (that's my oldest stepson in the photo). I don't actually know what year this set was manufactured, nor when my in-laws purchased it, but would guess that it was used in that room for possibly close to 40 years.
I found the assembly instructions for the chairs (and also the table) recently - in the basement:
The legs of our table are different than the ones on this table (from the Atomic Living blog) :
I managed to find a few other images on the web of similar sets:
Sorry I wasn't able to post a current photo of our set - we aren't using it right now. I wish the top had a different finish, and I'd love to get the chairs recovered in a period-appropriate vinyl - something with an atomic feel, you know?
But it's still pretty cool.
