what is weight capacity, what is width of seat

The seat weighs 2lbs. It is about 28 inches wide (think about a therm-a-rest) and seeing as the webbing is all bar-tacked I would bet it will hould upward of 1000lbs. I wouldnt test that, but you should be able to sit in it, have the pig hang below you and have no problems at all.

This will hold any normal person that can get themselves up a cliff. I am around 190lbs and have used it no problem. Width, I dunno, but wide enough for a big guy like me. It is not designed to be the luxurious hang out, just ease the pain of hanging belays!
