Make sure you take all the sheets, etc. Off. Then try laying it out in the sun for a day or two. Bring it in at night, and if there's any chance of rain again. It's best to get it out into the open air as fast as you can, or it will mildew & be unusable. It also depends on how wet it got. If it got really soaked, you may need to toss it out & get a new one. Air dry it a little longer than you think it needs too, so it dries on its inside. After you feel it's dry enough, spray it with some Febreeze or Lysol, & let that dry well. Then bring it inside & you should be good to go.
