I've had this same bed for years and found this question because I was on-line looking for the pillow that goes in the bed. Can't find it or the bed anywhere anymore. I wash the pillow more often in the washer and dry it in the dryer but the cover for the wicker I throw in the washer and then put it on damp. I, too, put it in the dryer the first time and had to have a man put it back on the wicker for me. Should have known. It's the same with your couch. I've always had cotton fabric on my couches so I can throw them in the washer when they get dirty. I then put them back on the pillows from the washer and "stand" them around my living room until their dry. Only takes overnight. Same with the bed.
