Exactly as described online - size, and aesthetically. The one minor downside is that the lid of the storage doesn't have any lip to catch on the inside of the rim of the ottoman, so it does slide pretty easily when putting my feet up. 
But it's exactly what I wanted - fits easily under my desk, holds a lightweight blanket and a sweater with room to spare. Also, the green matches the green of the Gustavo Task Chair nearly perfectly!
