Son, if you're out of shape and overweight, the design engineers didn't take you into account too well.

Many are built for the heavy weight user -up to 300 pounds.
And due to this many weigh more than 25 lbs, a not comfortable trek for the bad back and out of shape.

I use a tree stand from the early 90's. It's an heirloom. Comes with a weight limit of 250 pounds. A rarity in this modern environment.
