I purchased the Cube as an extra seat in a small studio space for the purposes of recording instruments where it is convenient for the musician to sit.
I have had it only for a short period and so cannot comment on its durability (although it has been heavily used to date) but i have found it so far to be lightweight, compact, and easily stored out of the way when not needed. Without a back support it is easy to get microphones in a variety of positions and its construction and materials means you get no unwanted creaks or sounds picked up by the microphones.
Its functions perfectly for the intentions of my use and it looks pretty cool also!!
