Glad you got one you feel comfortable and safe in, not sure which seat yours has but the seat on my Rivers Edge Big Foot Brute hang on stand is comfortable enough for me to have done an eight hour stint at 18 feet. If more paddi g is needed consider a partial packing blanket, that way if one of the kids get overly cold they can wrap up in it.
Yes I know with a 30" W x 37" D platform it is the size of a dance floor but beats something the size of a postage stamp.
