I agree with Pika; in my case your 7 lb. chair would add 58% to my pack's base weight (everything but food, water, fuel) and exceeds the combined weight of my sleeping bag, pad, and tent.

While getting up and down from/to the ground is getting more and more difficult as I approach my 84th birthday, adding 7 lbs. to my pack weight would make even a short trip impossible.
