CleverMade CleverCrates 62 Liter Collapsible Storage Bin/Container: Solid Wall Utility Basket/Tote with Lid, Charcoal

I am finding this to be an excellent product. I like that there is a cover, and that it can be attached to the underside if you don't want to use it, but want to keep it with the storage bin. I was concerned about the sides coming in when you don't want that to happen, but I found out after looking at it, that if you push from the inside out on the lower corners of the end pieces, that they will snap into place and lock. When you want to fold it up, just firmly push the lower corners in the other direction and the sides will unlatch and move in. That is a big deal to me!
