Just saw this at the Allegheny Sport, Travel and Outdoor Show in Pittsburgh....it is amazing !!!!!
The inventor was there and his brother, who has multiple sclerosis, which is why he started making them.
I personally know several people who have lost the bottom of thier stand and fell, one guy with a broken pelvis and another with a shattered ankle.
Haven't been in a stand since and would definitely use this one piece design.
A lot of room to sit and stand...built solid.
Was on that show INVENTION USA on the History Channel
He said he will be at the Niles Sportsman Super Show and Bowhunting Super Show in Cleveland
