This bed is similar to the one that is cheaper (looks the same minus interior cushion.. not sure the exact name). I ordered both so see the differences and there really isn't any. I do like this and the fact that i can wash it often. However, when I washed the cover the zipper didn't line back up. It could still zip, but it was wrinkly. I washed the top on warm and dried it over a line so I am sure there wasn't any shrinkage from the dryer or wash. Not sure what happened. The bed is a little loud when its stepped on, but it does reduce the odor because of the protective cover so i'm happy overall!
