Nothing seems wrong with the assembly of the drawer. The issue might stem from the railing inside the dresser itself. In this case, I strongly recommend having the product exchanged at your local IKEA store's Returns & Exchanges counter. Your sales receipt is required. If your purchase was made online, you can call us at 1-866-866-IKEA (4532) to set up the exchange or contact us on Facebook (IKEA Canada) or Twitter (IKEACASupport/IKEACanada). Tack!
