That just isn't reasonable. It damages the wall. Many people have basement heat, which means a 3-inch gap. Either you make a huge hole for a toggle bolt and then lose the hardware forever, or you have to find a stud. Lots of people are incapable of finding a stud. People want to move furniture for vacuuming. Renters aren't supposed to drill holes in the walls.

The reasonable solution is weight in the bottom, but that is either expensive to ship or the customer must provide it. A slab of lead would be great. A water tank is an interesting solution.

Yeah, I think this is a pretty classic example showing how almost no one actually reads the manual or follows the instructions.

We tried with these Ikea models, but couldn't do it. Our apartment walls are very dense, and it's almost impossible to drive a screw through.
