I wanted a deck box that could double as a seating bench and was large enough to store my patio furniture chair pads, pillows and grill supplies. This one checked all my boxes. ASSEMBLY: Instructions were clear and I watched some of the assembly videos here. We assembled in the house and then took it outside. Everything aligned exactly as expected. It truly did take only about 20 minutes plus a little more time later for the hydrolics to be installed on the lid. Each of the panels is labeled for easy assembly. I did solicit help from my young daughter to hold things in the proper place while I assembled, but there was no issue in assembly. Some of the sides are easier than others to fit and click into place. The lid was an easy installation and I seriously believe if we are careful and don't fling the lid open on one side, it will last very long. The hydrolic hinges work well to keep the lid open. Hinges were easy to install. I do plan on keeping it locked just so the winds here in the High Plains of Texas won't be tempted to open up this treasure chest. COLOR AND SIZE: I ordered the gray 100 gallon size deck box. It is a taupe-mushroom gray. The color matched the photos here and the size was larger than I imagined which is a benefit for me! It isn't too tall for someone to sit comfortably. STURDINESS: The way all the pieces fit together makes up the sturdiness of this storage box. I do believe that two adults could sit easily on the lid, though we've not tried it yet, we did with just one person. This box has a 660 pound lid capacity. It is light weight yet feels so durable and I feel it will last a very long time. The lid is more flimsy than I had imagined and when opening and closing, hinges work well but be careful with it as the lid mechanism isn't sturdy as I'd hoped. The lid is the reason for only 4 stars. Right now it is fine though and we are happy with the box as a whole. LEAK PROOF: The same day this was assembled, we had a thunders
