A:Answer we washed our king comforter in the washer, In fact, we washed our large dog bed first and it came out great and second we washed our king comforter. We have the matching dryer also. The comforter will fit in the washer and it came out really clean. We put it in the dryer with 4 dryer balls. I took it out a couple of times to rearrange it and put it back in for another 30 minutes so it would completely dry. The final tally, it came out clean and the colors were brighter.
