Under the mattress there is a pillow top mattress cover. Pull it out and put it on top of the mattress and remake the bed. I don't know why they keep it under the mattress, but that's where it is if you want to have a softer bed. No other issues at this resort. Great vacation and great food. Bring your own steak knife at the steak restaurant if you want to be able to cut your steak..they give you something close to a butter knife. Don't get the fillet..it's not the same thing as you get in the U.S. It's only 1/2 inch thick. Japanese restaurant was the best..good food and so entertaining by the chef.
