I have bought many Step 2 products over the years for my 4 children and daycare center but I was hesitant about this item after reading the reviews, but I needn’t have worried! Was super easy to put together- used a little elbow grease to push those screws into the plastic and it took me about 2 hours to put together once the pieces were organized. The plastic is sturdy, the unit is not tippy, is very securely put together with bolts and nuts that are absolutely. Hold safe. I believe o will have many years of use of this product.
