Very sturdy, and exactly what I had wanted! Looks exactly like the picture and is a great buy for the price! 
But OH DEAR GOSH was this a pain in the you-know-what to assemble and mount! I’m genuinely surprised my husband and I are still married after working on this together. I was about two misplaced shelf pieces away from having a 160 bonfire in my living room. It was a raging nightmare of unlabeled bolts and screws and I will forever be convinced that the south shore this company is named after is the banks of the river Styx. There is no other way this product could be so beautiful, but also so monstrously evil. 
I’d buy it again in a heartbeat, but I’d most definitely have someone assemble it for me.
