Blender vs. Sledge Hammer

Brooklyn Bedding claims its memory foam retains its shape through anything, but the makers of the Dynapac CC722 think this bedding company is just dreaming. The 38,000-pound double-drum roller sets out to flatten this foam once and for all.

Later, it's a battle of dog versus machine.
