I am really pleased with this purchase. It is extremely robust and of good quality. The dog bed is surprisingly light, in spite of it's size. My dog loved it from the word go, trying to lie inside it even before the bedding had been placed inside. As a dog who likes to nest, she is secure within the raised plastic sides and happily curls up inside. Had I been able to purchase an even larger size, I would have as my dog has really long legs, but she folds up neatly inside the largest size like a piece of origami, perfectly content. I will be first in the queue if this bed is ever sold in an even larger size as I think it is an excellent product.
