I found this ridiculously complicated to assemble. If the assembly service wasnt more expensive than the actual item, I would have chosen that! 
No QR linking to a proper assembly video, just an animated guided manual. 
I also found the pre-drilled holes for the 52 J screws were barely drilled and I had to manually pre-drill the hole myself, as the J sized screws are so tiny and difficult to maneuver without pre-drilling holes properly. 
I found the bottom pieces of each drawer to be very flimsy and warped easily. This does not bode well for years of use. 
In general, Im disappointed in this item and the very long and complicated assembly.
