The original Treelounge is a great stand. While it does weigh a lot, it is a very safe and comfortable stand! As to being noisy, if you practice setting it up, it sets up with ease and I have moved it from tree to tree in one afternoons time and after getting comfortable, I've had deer come right out under me. So it wasn't too noisy for them!
I will say look at some of the others on the market today, I've heard some bad things about the new Treelounge and very good things about some of the other brands! Good luck!
