Bigger  than expected  I ordered the size for up to 90 lbs., my Lab is 88  lbs. and there is more than enough room, he likes to sleep stretched out so the bed is perfect for him .I even laid on this super supportive and comfortable bed too...naptime 

Pros: come packaged small but in no time airred out to size
Cons: cover could be a little thicker, havn't washed yet
