First let me say I am a long time customer of Wayfair. This bookcase is is really junk. I was assembling this when the bolts ripped through the cheap particle board falling on top of me. It left me with a large swollen spot on my head and a rip on my arm requiring 7 stitches at emergency room. To add insult to injuryVery Wayfair is charging me 51.00 to ship this junk back to them. Very cheaply made product with horrible instructions. Do not attempt to assemble these alone. They are too heavy for the hardware included.
