Under your bed is one of the best places to find extra storage when space is tight. If you have an old dresser you're getting rid of, you can reuse the drawers to boost your bedroom storage with just a little work.
If you don't have an old dresser on it's way out, you can find cheap ones at your local thrift store that have seen better days. After all, all you need is a drawer or two! Pick up some casters from your local hardware store, screw them into the bottom of the drawer and you've got a new sliding drawer that fits under your bed and is easy to use.
If your bed is too low to the floor, use a few risers to boost your bed until it is the right height. You'll end up with an inexpensive storage option and repurpose furniture that would otherwise just head to the tip.
