Jessie’s bed

My 89 yr old father in law has been bed ridden for two years He needs a special mattress that can turn him every few minutes so he can avoid bedsores. His wife cares for him at home and has to get up every few hours and turn him manually. Both jessie and his wife never get a good nights sleep and he is suffering from bedsores that won’t heal. They live on a very limited income  and the mattress they need it out of their price range. Please help us improve his quality of life.
