Dropped a fair amount off at goodwill, including an old ikea chair we've had around for a few years since picking it up for free from our old apartment's recycling room. It wasn't super comfortable, though, and the space in the office is now being taken up by a second desk (also free, haha).
A ton of stuff set aside to return to my parents, too. They keep dropping their crap off without asking, ugh. Some of it is useful, I'll admit, but most is metric tons of crap they should just take to Goodwill. Parents: please do not do this to your children. Especially with the message "if you don't want it, give it back to us". Just let me get rid of it if you insist on dropping it off! </rant>
Anyway, finally went through a lot of decor that was trapped in a closet since we first moved in. Brother took his mattress finally, so we can access the closet now. Come to think of it, my biggest clutter problem is definitely family members!
