I added a waist belt. Bought one of the Buddy Loc belts at Walmart on clearance ($4.00) stripped it down and bolted it on.

Put a hook on each side under the arm rests for hanging things.($.75)

Added pieces of pipe to the front on each corner to put branches in to add cover. ($.50)

Replaced the strap for my toes with a rubber bungie cord. Holds my feet better no matter what boots I have on. ($1.50)

Added quick release buckles to the seat the match the ones on my hot seat. I can clip it on for more comfort. ($2.50)

Bow rest of course, and padded straps.

I can spend the whole day in it without any trouble.
