These plastic bins are lightweight and come with four wheels underneath, making them easy to slide out from under your bed. You can use them for storing winter coats or items you want to access more frequently, like gym supplies. The handles latch into place when you close it and are also intended to make it easier to pick up the container when you are moving (if you’re storing papers or books, it can get heavy). One box is about 6 inches tall and is designed to stack easily. If your bed is slightly taller than average, you can fit two stacked on top of each other. These boxes are available in both a 50-quart and 60-quart version.
