Our shoe rack will organize your shoes and bags with ease. Can also be turned into a bookshelf to store all the books in the living room. And you can store towels, toiletries, etc.We worked hard for better quality, the panels got wider. This product is stronger and better for holding things. The mortise on top is for attaching another shoe rack. We adopt thread structure, once connected with another shelf, it will become one, and the upper shelf will not shake. We changed the hinge in the middle to be movable. If the panels are not aligned to begin with, you can move them around a bit to level them out. We have changed the hole where the foot connects with the panel to be larger on the outside and smaller on the inside. The advantage of this is that the screws will not be crooked, keeping the four feet in line with the ground.
