While this deck box is large enough to hold most of my outdoor cushions and pillows, I was a bit disappointed that the sides are not waterproof. The insert provided is adequate however there is not enough Velcro to secure it well. Also, when it rains, water remains on the lid, so when you open it, water cascades down and some does make it’s way into the box dampening the cushions on top.  I kept it because I plan to move it to an area protected from the elements.
