First I put risers under the four posts of my bed. I worried they would make the bed unstable but surprisingly, they didn't. I've even gotten on the bed and jumped on it and it remained stable. It is a tad high so everyone may not like that but I think it's kind of fun.
Another storage solution I found in my extra bedroom is these wooden trunks. In the top one I store my camera and all my charging cords that I need for all my electronics. In the bottom I store items I don't use often that I don't need to worry about infusing the old smells of the trunk like unused Cd's, a box of buttons and frames not in current use. The trunks are a cute way to add that badly needed space in an attractive way.
It may seem like simple ideas (and they are), but any time you can reclaim more storage space in your house, it's a win for the organized home.
