our old beds are all starting to flatten out (they're over 10 yrs old).  i replaced the family room bed with this one. although it is smaller than the old one, my 55 lb vizsla (who prefers his own bed over the couch) comfortably fits on it with plenty of extra room for my basset mix if she wanted to sleep there too - she prefers her couch.  it is super thick and firm. my v appears to like his new bed. i keep sheets on the beds to keep the bed covers clean. it arrived in a small box and completely filled out in a few hours. great price too.
