Queen size bed with mattress (Rayville Louisiana)

Any condition of a queen mattress is fine.. I’m currently transitioning from homeless.. and I have a 15 year old son that is 6 feet and 3 inches tall . I have been unable to find him a bed. I am considered very low income due to no income at all.and I’m a single parent. I just got my apartment at the rayville west apartments and He has no bed to sleep on.please anything will b a grateful blessing for him.
