Just to sidetrack a bit, I think the Living Spaces guys are contractors.
I knew a guy whose family's trucking service had a Living Spaces contract.
Depending on your HOA, I would put the stuff out with a 'FREE' sign a few days before the WM trash pickup, if it walks away on its own, then call WM to cancel the pick up.
As for Craigslist, same thing, put the ad out and the stuff out (if you're not selling it) for a few days and see if it disappears.
Another option is a community site called NextDoor.com. Not sure if your neighborhood is on it but you can post that you are giving away your furniture there.
My neighbor had his coffee table on his driveway for a few days. Saw his gardener checking it out and then 2 days later it was gone... so QwertersList could work too.
