Great Looking Shelf
Color: Brown, Size: 4Tier48in, Color: Brown, Size: 4Tier48in
I love this shelf! It took two people to hang it and you definitely want to ensure you hit a stud on at least one side or 1-2 screws if mounting between studs. It is heavy but a single person can lift it, just not maneuver easily due to its dimensions. It has a ton of room and fits mini helmets nicely in my office. Where I mounted it made it difficult to an extent to install but if you are even somewhat handy, you’ll be fine. You absolutely need a stud finder to hang this shelf. Sorry, I’m married! I would buy this shelf, or versions of it, again. Very practical and useful to display autographs, housewares or decor. Last note: do not over tighten the poles. The wood is soft and the poles are light weight. They are not traditional black pipe and weigh far less.

AWESOME Look and Quality
Color: Brown, Size: 2Tier60in
I love these shelves and have bought additional for other areas in the house. I love the look of the industrial pipes, the color of the shelves is perfect, they are sturdy and hold a lot of weight. They are somewhat difficult to assemble, but it's expected as hanging shelves are never fun to hang. I love them. If you are on the fence, just do it :)

Nice, but a bear to install
Color: Black, Size: 3Tier48in
Quality product that looks good on our shiplap wall of the wet bar space. The install was a real trip and extremely difficult. You definitely need 2 or more people to install as the direction tell you to put the entire item together, then hang on the wall. This makes it impossible to do yourself.
