I put this bed together today and so far, the dog I bought it for loves it.  I put her bed on top of it and she curled right up.  I think she likes having her bed off the floor.  I plan to use it as an outdoor cot for her to have on our porch and it looks like it will help keep her cooler in the summer months.  I wish they made one sturdy enough for my biggest, heaviest dog.
