I have one which I inherited from my Nana (already stocked with sewing machine and fabric etc)
I would have never bought one especially, because they are so BUTT ugly (maybe they look good now?)
But they are brilliant for storing your sewingmachine. Although I reckon you could adapt a small tv cabinet or similar for cheaper.

Given that I rarely use my machine and we don't have heaps of space or a room to devote to sewing, it's a good option to have stuff dumped on it!! It is also very compact compared to other methods of storage.
