Hi, I am about to bring my bedridden father back home from Hospital. He's 71 years old. The Doctors said he is at risk of developing "Bed Sores". We have bought him a special mattress and we plan to have him on a special diet plan.He has very frail and thin skin. I have researched and found out that there are special clothing and bedding/ Any advice? Have you tried any ? Do they work? Any special clothes or bed sheets?
