The pet bed is well constructed, however, I made this purchase based on the advertisement for this product.  The product advertises the SNOOzZzone Pet Comfort system but what they neglect to tell you is that it is a separate purchase.  Although the first 2 sentences under product details lead you to believe that it is part of the purchase of this product, it is NOT.  I was disappointed to find that out only AFTER I had purchased this non-returnable product.
