These beds are amazing! I laid on them myself after the 48 hours it takes for them to puff up to full size and they were so comfortable. The largest size is perfect for our 90b catahoula who usually has his legs hanging off beds our 80ish pound mixed breed probably would have been fine with the next size down. We got at a great deal on sale, plus the discount for opening wayfair account and free shipping. The shipping did take quite awhile, but for free cant complain. Ours didnt have any smell to them from the foam.
