Our Dorado had a hide a bed .. the mattress was worn out and probably not very good to begin with.
We ordered a 3 layer memory foam mattress made for a hide a bed. You must be careful, when ordering, to specify the replacement is for a hide a bed, as it cannot exceed a certain thickness, since it must fold up into its enclosure.
We were happy with our replacement mattress.
It cost us over $500.
