The cube was easy to assemble, appears to be very sturdy, and had a small enough footprint for the area I was targeting. I also really like that it's made of recycled paperboard and is eventually recyclable itself if/when we ever need to get rid of it.
My only complaint is that the day I picked it up at the store, WalMart had a very similar product of its own for $15 less. However, they didn't have any of that product in white, so I ended up keeping the one (the Double Cube Plus) I'd previously paid for. Bottom line: I think the price is borderline too high and I'd like to see it cheaper so that furniture like this becomes more widespread. Full disclosure: I looked at prices on the manufacturer's webpage and they were higher.
