My lab rescue, Charlie is loving his new memory foam bed.  He is a big boy and fits on the large bed.  (My cat is trying to use the bed too when Charlie is outside)
It is a bit too large to fit in his crate, but he enjoys lounging on it during the day. 
It is delivered in a small package and expands after opening it.  So it takes a little while for it to obtain the shape you see in the photo
