Organizations That Help Disabled People Get Furniture?

Being that I'm on mental disability how do I go about getting help with a new box spring and mattress?

We have a near and dear friend who had become disabled. She worked as long as she could, but her conditions (multiple) worsened through no fault of her own. She is elderly as well, and lives alone. Her things have become old, broken and tattered. We've had to throw out the curtains and sofa and some other things. We can help her with the basic things, however furniture is beyond our means.

We have two disabled children with expensive needs/issues, and one college bound son as well. It breaks my heart we can't do more for this sweet woman. I've looked all over the internet. Even Facebook and Craigslist. Most things I come across are stained and old as well. She deserves better than that. Isn't there any better resources for these people? Salvation Army, Goodwill, and asking your church are pretty shotty choices. (You don't have to belong to a church to be a good person and they really should focus on making their schools affordable for everyone rather than giving handouts to everyone that claims to be a good Christian.) Surely there must be something out there that provides nice furniture for disabled and or needy people? It's America for God sakes where people take multiple luxury non-necessity vaca's a year, and waste money like it's water. Does anyone know of a foundation or group that helps these people with hygienic, quality items?
