I am strong and this wardrobe is a LOT bigger than me.
I mean, it's hollow, but it's 3x2x6 and made of wood. We alternate with who pulls the refrigerator-moving dolly because the edge digs into our arms and in my case, leaving my arms slack while I pull it pretty much exhausts them. Part of the weight of the wardrobe is on the wheels but I think because I tilt it down so far a lot of the weight is on my arms, too.
Today I was pulling it and it wasn't so bad! But afterwards I rode in the truck I thought the door was locked because I couldn't get it open but it turns out I was just too tired to pull on the door handle hard enough.
