A couple of years ago, when we were creating a play area in our home, this storage bench from Ikea was exactly what we were looking for. Too bad it didn't exist then. If, like us, you're looking for rolling storage that also functions as seating and doesn't take up too much space -- all for less than $100 -- this might be your solution. We can see a few opportunities for cosmetic hacks to this piece. If you're not hot on the black storage boxes included, they look like they could be easily resurfaced with a little fabric decoupage action, and the handles replaced. Or you could just switch them out for different boxes. Add a simple foam cushion and you've got a sweet little sitting area.
Or if you're feeling really DIY, this piece looks like it would be pretty easy to replicate in its entirety. (Funny how these projects always sound so easy when you put them in writing, hm?)
