I used to have one made by Gorilla. Can't remember the model. Only drawback that I could find was that it weighed nearly 30#, a real pain to haul it up the tree. Comfy as all getout.
I can see Bronko's point about the arms rests getting in the way, but I'll take comfort every time. Arm rests of some sort take a lot of strain off the shoulders and back which means you can stay in the stand longer. And how many times has an animal come near your stand after you had left it? That's one you may never be able to answer.
