Is a person with more body fat more or less likely to get pressure sores?

Obesity PU: Obese patients are more at risk for pressure sores than a usual weight patient.

Less: Generally, people with a larger body mass have a lower risk for pressure sores because they have more padding between bony prominences and the skin. However, when pressure sores develop near the bone (deep tissue injury), they tend to be much worse in larger patients because the tissue damage can be extensive before they are noticed.

It depends: Obesity itself is not the important factor. Nutrition is. If someone lacks the protein, vitamins and minerals to maintain and heal, there obesity will not be protective.
