This was not an easy assembly. I purchased two of these and the 2nd one was more difficult to put together than the 1st.  I didn't find them to be super sturdy and the two composite panels that slide in the back are joined by a black plastic piece...not sure why there isn't just one panel so there isn't a seam.   The shelves also came with screws that were supposed to screw the back panels to the shelves, but there were no pre-drilled holes to screw them into.  For the low price tag, you get what you pay for.
