This comes in separate pieces and must be assembled. It took me about one hour. The pieces do line up but once assembled the dock box isn't aligned and looks very cheaply made. The interior is small and holds the following items. It has a short bucket of pool chlorine and the vaccum hose for the pool and the pool skimmer net. That is all the interior will hold. If you need to store lots of pool supplies this is not large enough. I have a pool cleaning service so I don't need all the chemicals stored. If it wasn't so much trouble to return I would have sent it back and ordered a larger dock box. The cushion on the top has regular canvas that will be faded and worn in less than a year sitting in the sun. If it's under cover it may last longer.
