The shed is really easy to assemble if you take the time to lay out all of the parts initially so you can identify them quickly during the assembly process. That's a no brainer. If you are putting the shed on a concrete base, make sure you have the base pour at least one foot larger that the shed dimensions.  I.E., if you get the 6'X8' shed, do a 7'X9' slab. The shed does not seem to be very substantial at first but as you assemble it, it becomes pretty sturdy as the supports are installed.  Good for the price and will do everything I need it for. I'm using it for storage of swimming pool items and toys.
