I bought a used Nieri leather sofa recently for a seventh of the original price. It is supposed to be a solid high end sofa (or so the seller said; it was the most expensive sofa of the hundred they were selling), but is feather light. I was suspicious, but bought it anyway because I liked it. So far it has withstanded the kid jumping on it in various ways.

I wonder, is it even possible it's solidly made despite being very light?
