My wife wanted to completely remodel the kitchen. We decided to put in IKEA cabinets first, with a tile backsplash, a new floor and new ceiling to follow. I was almost finished, with one wall cabinet and one base cabinet for the trash left. We had chosen a 24*24*30 cabinet with a full height drawer, and one short inner top drawer. When I went to build the full height drawer, I soon discovered I had been given the wrong instructions, and this drawer had extra parts that were different than all the others!! So after much thinking and measuring, I finally figured out how it is built. As IKEA seems to have no online instructions that I could find, I made this video in case anyone runs into a similar predicament.
The cabinet is a SEKTION SE 24*24*30, with an UTRUSTA 24*24*30 door and MAXIMERA 24*24 sliding shelf.
