Single bed or just mattress (Higham North area NN10)

My son's friend needs accommodation for the summer until he returns to uni in Sept. He's mum passed away and he's dad has basically thrown him out. He's uni accommodation finishes end of June. I said he can live in my shed but i need a bed for him.
Any offers of a single bed gratefully received, however my car is a small hatchback so can't accommodate double or king sized mattresses. Thanks
