Baby seat with toys (top spins around to different toys) - $12
I used this A LOT when the baby wasn't able to sit up. I would put this on my table so that they were at my height while working in the kitchen. It worked as a table chair to feed them. It was the chair of choice for a long time. This works awesome until the baby gets to the point where they can push with their feet, then you would want to have it on the floor.
Baby activity jumper seat - $20 (can be broken down for storage)
Baby activity jumper seat - $35 (this seat folds down for easy storage vs. breaking it down)
