Looking for an idea to use for a seat in my 3 person ice tent. It is usually just me and sometimes one other person. Thevtent is about6'x6'x6'. I have been using a buck with a lid for years but it is getting hard on my back. Besides the idea of stacking more buckets on top or finding a tall fold out chair, does anyone have any ideas on an at leadt somewhat light-med weigjt altetnative?
