ELI5: Scientifically speaking, how do severely immobile people become fused to their furniture?

Skin is not a solid substance. It is made up of cells and layers. If you press skin down with enough weight, the fibers of a fabric can become entwined in the skin. This doesn't happen with every fiber or every boundary of skin cells, but it can happen enough that it appears that the two are intertwined. This is especially true if the weight on the skin exists over an extended period of time, and since morbidly obese people are often in the same position for a long time, you can see how this happens. This is much less likely to happen with smooth fabric, but since all fabric is made up of fibers, it can happen anyway. Just think. Press down on a slab of skin with a pressure approaching 100lb/sq in. over a long period of time. Would you expect anything else?
