If you remember folding aluminum lawn chairs, you are getting old(er) like me. Nowadays, lawn chairs are either plastic or fabric attached to a steel frame.
I think the aluminum chairs were actually lighter in weight, but remember how the slats used to fray and then split? Sure you could repair them with string or rope, but they didn't look like something you want to invite the Jones family to sit on when they were visiting for a barbeque.
Here's a folding chair you could invite them to use. Or you could offer them a folding couch. I'd like to see the Joneses keep up with that.
