I learned about bunk beds from a friend of mine. He wrote this guide while he was in college and never asked a professional. It taught me tons of great advice, like where to put the bed, how to collapse it for storage, and where to find the cheapest deals on bunk beds. Many retailers rip you off in the long run, charging you too much for shipping and handling and then giving you a measly three month warranty. I learned, via this book, how to establish myself as a strong buyer and not get tricked by salesmen and their lies.
