We had 3 original Beds, then ordered 2 more for when we travel. Love, love, love the originals, but these new ones have a tighter radius on the opening, which our hounds couldn't close after nesting. Our Iggy and whippet got cold and ended up in our bed.  Called the manufacturer and explained the dilemma, and the wonderful Amanda sent us the original and relaxed replacement tubing for the new beds. Still, why did they change the beds we love? 5 stars to Amanda, 3 stars to the new beds, 5 stars to the original Beds.
