I had been looking for a small corner shelf to fit between my dresser and the door in my bedroom. The wall is only about 17" deep, and finding a suitable shelving unit was proving difficult. I've always been a fan of IKEA Hackers, so I wondered if maybe there was a product at IKEA I could hack to fit the space. When the lack side tables came on sale for 50% off back in January, I bought 4 of them. My goal was to cut them down to a square size, and stack all 4 on top of each other to make some shelves. Cutting the tables was challenging since they are mostly cardboard inside. They were cut to 16" on two sides to make a 16 x 16 square. The two cut edges will face towards the wall so you won't see them. The two finished sides will face out into the room. The legs were attached with glue since the original holes were cut off on three corners. The uncut corner leg was screwed in normally. I put 4 legs on the table serving as the bottom shelf just for stability. The other tables got only 3 legs so the front of the shelving unit would be open and not obstructed. Then, each table was glued on top of another. We had the makings of a four-shelf unit! For extra stability, long brackets were used to secure the legs and the table-top once it was built. The unit was attached to the wall in the corner with some wall-mounting brackets to prevent it from falling over (not shown). It turned out just as I had hoped! I cut some bristol board to fit on the bottom of the top table so it would appear dark (otherwise, it was just particle board and really noticeable since it was so high. I plan on painting it down it road, the bristol board is a temporary fix!) And the best part, it only cost $20!
