Arrow Foundation Kit for 5 x 4 Sheds & 6 x 5 Sheds - FB5465
Easy to assemble, but wasn't really needed except if you want to have items not sitting on the ground. It is a frame that has to have plywood or something else like plywood to have the items not sit on the ground.
ProsEasy to assemble
ConsReally is not needed, and kind of pricey for what it consists of.
