This comes unassembled and was very easy to put together. The instructions did not come with the package but I googled and found them quickly. It does feel flimsy until you get it together. At one point the instructions, which are pictures, indicates you will need two people but I put it together by myself with no problems. The instructions are very clear and no steps are omitted. I appreciate that. I intend to use this to store outdoor cushions and a hammock. As far as space goes it is actually bigger than I need! As for durability I will have to get back to that when winter is over. The color will blend in nicely. The only caution I have is when the lid closes there is a bit of a snap just before the close so I'm going to put a lock on it to keep out prying little hands.
