The walker/rocker/bouncer came mostly assembled. The time consuming part was attaching the cloth seat. If I were to do it again, I would take the seat section off of the main assembly to attach the cloth seat. It would have been easier to hold the little seat section in your lap and flip it around, then flipping the whole walker back and forth. I like that there are 4 different modes. It's versatile and will get a lot use. I have it set to the rocker mode with the bouncer foot pad, and my granddaughter loves it.
