This is much lighter than o expected. The plus side to that is that I was able to build and install it by myself very easily. The firm side is that I’m a bit worry about it’s prolonged use with weight on it. The assembly is easy but watch out for how deep you put the dowels in. The holes are deeper than the dowels should go. It’s a nice looking basic shelf but definitely used cheap (some pieces are not solid board they’re hollow) materials.
