Answer:

Time to buy a new one, throw it out
Once it starts to smell, it can't be saved. Get a new one and make sure it is not susceptible to mold. A sleep number mattress might be a good choice. You also need a dehumidifier.

Don't forget about all of the things he leaves in the tree
Moisture, freely floating in air gets trapped in anything which can absorb it, like cotton mattress, pillows, cloths etc., To cure the present one. seems like impossible. However, u may try to spread it under the hot sun, if it is possible, and evaporate the trapped moisture. Otherwise, buy another one, with material which will not absorb moisture and spread a rubber sheet over it. Then, spread a thick cotton bed-cover over it, so that your body heat is not fully reflected on you and feel comfortable. Keep a check once in a week about its condition, until the climate changes. Best of luck!
