We originally bought the Fisher Price Ocean bouncer for my son, and he liked being in the boucy seat if we had to put him down.  We decided to buy a second bouncer to leave upstairs instead of having to bring it up and down the stairs with us.  I didn't want to spend as much on a second one, figuring we probably wouldn't be using it too much anyways.

My son LOVED this one, way more than the Ocean one.  He really liked the plush toys (the plastic ones on the other seemed to annoy him)  I really liked that when he was a bit older, I could take the individual toys off for him.  The vibrate part...
