The Serta Pefrfect Sleeper As far as pros.........the cats enjoy sleeping in the dips where we TRY TO sleep.
This mattress has hurt my back ever since my first night on it! And now both our queen size and my son's twin size mattress has developed dips. My son is 5'9" and 145 lbs. Not very heavy. As soon as I'm financially able I will replace both mattresses with something else.
