Customer service is awful. Shipping is awful (usually FedEx, which sends emails changing delivery times daily). Merchandise can be good or ridiculously shoddy, and not packaged sufficiently for the contents to arrive unscathed. And God forbid you need to return anything--Wayfair makes it nearly impossible. I bought a mattress and didn't like it; trying to return it within the 90-day window is proving extremely difficult, and I've been trying for over a week now. Wasted hours on the phone and computer trying to get it picked up and still nothing. Will never buy from Wayfair again.
