Quite a well-designed construction so that it can be easily assembled and the final result is reliable. When assembled, it is quite stable. I did not test the maximum weight that I doubt it can withstand, but it can lift quite a few kilograms. I combined it with a 90-inch, screwed them together (but not to the wall) and I am completely satisfied with the result! It is worth its money. I might get more. Definitely needs a hammer and a screwdriver for assembly. For those looking for instructions, it has a sheet between the shelves!

The shelf is very nice!! It's worth its money and if I had more space, I would buy a second one. The difficult part was assembling it at the beginning until the bases and the first lower shelves were stabilized. Once you stabilize those, everything else becomes easy. Necessary for assembly is a hammer to better secure the metal frame to the joints, a small screwdriver that will only be needed for the metal pipe in the middle of each shelf, and a marker to mark the internal joints so that the shelves don't go in crooked and are aligned with each other. Once you do the first 2 lower shelves, the upper ones become very easy. It is ideal for storage in a house!

I bought 5 shelves of good quality and good price.
Attention is needed in the assembly to properly connect the columns with the shelf supports.
