EFINE 4-Shelf 23.6"x14"x47" Shelving Rack

I’ve bought similar racks for work that cost more but are sturdier. For what it cost, this is a decent rack and it works for my needs to store some kitchen pantry food items. Two key complaints: Each of the four support poles come in three pieces and it’s easy to get the middle section reversed, which will prevent you from getting level shelves. I figured that out the hard way. This seems like a bad design as it would be simple to make the middle section the same on both ends so that it wouldn’t matter which direction it was used. The other complaint is about the claimed “150 pound limit per shelf.” While the perimeter of each shelf is reinforced and could support that weight, the material in the middle of each rack definitely cannot. I can easily make the center of each shelf flex with light force (I’m an average size person with average strength). The shelf is strong enough for routine kitchen pantry items, but not heavy items unless said items are long enough to be supported by the shelf edges.
