You've spent the afternoon at home twisting an Allen wrench and assembling an entertainment center, but when you've finally finished, you decide it just doesn't look as good as that other little number you had your eye on a few displays over. It's time to head back to the blue-and-yellow behemoth to make a return.
IKEA's return policy in its U.S. stores is straightforward: You can return furniture, housewares, and just about anything that isn't custom (like cut fabric and countertops) or an as-is item with a receipt within 90 days for a full refund. You can also return mattresses within 90 days, but you can only exchange them for store credit [source: IKEA]. (Be ready to present a receipt and an ID with your return, a measure to curb return fraud.)
It's rarely OK to bring furniture back that's stained, scratched or broken unless those are symptoms of a defect, and sullied mattresses definitely can't be exchanged. But if you're returning something half-assembled and out of its packaging, don't worry — returning it that way isn't impolite at all.
