The upholstered bench seat was made from a piece of plywood cut to fit on top of the trunk, a 2" thick piece of foam, and a couple of layers of batting. A piece of upholstery weight textured fabric, that has a bit of an animal hide look to it, tops it off.
I did nothing else to the outside. All the leftover bits of shipping labels looked really cool, so I didn't mess with them.
Works great as an ottoman, bench seat in a mud room, or put a tray on top for a coffee table...And, oh yeah...lots of storage!
