We babysit my granddaughter 4 days a week while my daughter works, so we needed something to occupy her time when she wasn't sleeping. The walker arrived quickly (ordered it online). It took about 20 minutes to assemble, & didn't require any tools. My granddaughter enjoys sitting in it and playing with the toys on the toy bar. She is 4 months old, so has no trouble holding her head up. I DO have 2 complaints about the seat, however. First, there is no safety strap and/or harness to go around her waist and/or chest, so she tends to slump forward. To rectify this problem, I folded a receiving blanket and placed it between her chest and the walker tray. Problem solved! My next complaint is that, although there are 3 different height adjustments on this item, it's VERY hard to adjust it to the lower 2 settings.....it just wants to pop up into the highest setting, at which height her feet don't touch the floor. Overall, a nice product for the price, and another "plus" is that it folds nice and flat for storage. This way, when Kyri is not here, we just fold it up and stand up next to the wall by her pack n play.
