Extremely disappointed. I had a dog bed cover 40"x 32" that I wanted to use over the insert of this bed. The website stated this size, however I received a bed that was 44" x 36".  According to a rep, the jumbo size was not advertised correctly.
Not to forget, that they lost my  first order. According to a rep, the order was filled but not shipped. The bed came stuffed in a small box causing the box not  to closed properly. 
Secondly, I was not going to use the cover that came with the bed, but others might want to know that the material is cheap and thin which IMO would rip easily.
