Finding Free Furniture?

My familly is in dire need of furniture including cupboards, beds, and even kitchen cupboards. I have now recently taken in two family members and we have moved into a backyard flat and have absolutely nothing not even a fridge. I am a low income worker and I am at this stage taking care of and providing for a family of five. We are sleeping on the floor and our clothes, food, and utensils are at this stage all over the place, standing and stored on the floor.
