I received my box last Thursday afternoon. It took me about 1/2 hour to assemble. The instructions are clear and easy to follow. Although, I believe, it suggests two people to assemble it, I managed it on my own. The only slightly difficult aspect was holding the lid, while trying to get the first screw in place.
The box is quite sturdy, due to a part metal framework providing the additional strength.
The box is large enough to hold all the cushions from our 3 seater swing, including the side bolster cushions, the patio table chair cushions and 2 umbrellas with supporting poles. Plus there is still room for other stuff.
Since filling it up, we have had some torential rain showers. Hail and thunder storms, but the contents have remained bone dry. Very, very, pleased.
