Originally, when I opened it, I was shocked because it was one of those things were they vacuum pack it. It looked tiny considering I ordered a large bed. But I followed directions and 24 hour later it was big and heavier feeling than when it was in the box! I thought oh yeah, he can sleep in this. Originally, I was thinking of sending it back! I’m still trying to get the wrinkles out of it, but I’ve got to say my dog loves it. He’s a long-haired sheltie who’s hot all the time. He is not hot on this bed. The first time he slept on it. He didn’t move from his original position until I woke him in the morning. When he sleeps elsewhere, he flops around, trying to get comfortable. He’s been in the Cozy Bliss bed every night since we’ve gotten that bed and he’s completely happy! So I’m in heaven for him. One thing tho, those wrinkles from packing never seem to go away! I hope they will the more he uses it.
