Loading Couches, Etc.
Couches and other upholstered items require special attention. In general, care should be taken to avoid damage to the upholstery. A pressure point in the side of a couch or chair can create a "stretch dimple" that may be permanent.
Try to fit couches and loveseats together like puzzle pieces. This will help to create a more generally squared shape that will be simpler to fit into the truck.
Remember that the wooden frames inside upholstered furniture are designed to handle forces from above, so exercise caution when standing them on their back or sides.
