How do healthcare mattresses help prevent pressure sores (bedsores)?

Healthcare mattresses often use specialized foams, gel inserts, air cells, or zoned constructions to distribute body weight more evenly and reduce peak pressure on bony areas such as heels, hips, and shoulders. Some models also incorporate alternating-pressure or low-air-loss technologies that regularly change pressure points and help manage skin microclimate, which can be important in pressure injury prevention plans.
