What is the most comfortable, easy to store, product for guest mats on the floor? Memory foam? - foam floor mats

I must buy something to sleep for a mother and her two children on the ground this weekend to use. I want something I can roll up and store, not too expensive, but useful and meaningful for the customers in the future. I think a double memory foam mattress topper. Foamies or three single beds.
