The 4 tier shelf is decent. I would say it's somewhat sturdy. Everything you need is included in the box. You will need a screwdriver to assemble the unit. This can be a bit tedious. I found that the screws were easy to drop due to their small size. Also, make sure not to press too hard when turning them because you may strip the top of the screw. Even with that being said you do have a few extra screws in the bag in case some are lost or damaged. The overall assembly is quick once you get the positioning right. I liked that the legs of the unit had anti-slip caps. The shelves would be best used with lightweight items. This would be a versatile shelving unit for a closet, pantry, laundry room, or even in a hallway. I could see it being useful in a kitchen or an entryway as well. The nickel finish is pleasing to the eye and would fit any decor.
