My mom has the Einstein Jumper at her house from when my niece was a baby - I loved it and my son did too (4.5 months). We bought one for our house and it's "new and improved" and the seat is SO much higher than the older model - so high that my LO's feet dangle 6 inches above the floor whereas on the older model his feet touched the floor. He's a peanut (barely 24 inches at 4.5 months) but still, that's a huge difference and I wish we had realized it before we bought it since there's no way he's going to be able to touch the ground on the newer model for quite some time.

Thought I would pass along the review!
