My room is L-shaped and 143 sq. feet. There's not much floor space for putting in organizers (my wardrobe, closet, fridge, bookshelf, desk, bed, trash bins, etc. take up a ton of space) but my walls are completely bare.

My bed is also floor-level, so I can't store anything under that. I'm a really restless sleeper, so when my bed was normal height I kept falling off and hurting myself (concussions, bruises, etc.). So I had to bring it down to floor level.
