We are in love with the Step 2 Safari Truck Climber!!! It was incredibly easy to put together. The parts and instructions were packaged together well and made sense! We were able to put it together start to finish in 45 minutes. Our son loves it so much. It’s sturdy enough for him to climb on it without it swaying or bending against his weight. It’s much taller (in a good way) than we thought. Our son is almost four and tall for his age. He will be able to play and climb on this for at least a couple more years.
