In IKEA recently to pick up a new GUSLE lamp, we noticed a bunch of bright yellow business cards. Turns out they were for Konkord Assembly, Inc.
A full-service assembly company, Konkord's "furniture technicians" fiddle around with all those nuts and bolts and mysterious pieces of ready-to-assemble furniture so you don't have to. Prices may not be that cheap -- there's a minimum charge of $50, and rates range from $15-$25 for chairs to $65-$200 (and up) for wardrobes -- but the cost of saving you from a migraine could be worth it.
They'll help with non-IKEA furniture, too.
