Question: How much weight can each shelf hold? I bought a cheap wood one two years ago and the shelves have got to the point it looks bent.
Document: I needed 2 bookcases. I was cautious. I figured I'd order one and see how I liked it, then decide whether to order another. It arrived early. It had the exact dimensions the listed in the product specification section. It had all the pieces. None of them were damaged. It had instructions. It was EASY to put together (from in the box to filled with stuff inside an hour). It's holding everything that used to be on two smaller (and much heavier) wood shelves.
This was very easy to assemble, seems sturdy, and looks attractive in the space. One of the shelves was slightly bent, but I put it on the bottom with the bent part towards the back. The imperfection can't be seen, did not affect the assembly and does not affect the sturdiness. If it wasn't for that, I probably would have given the bookcase 5 stars.
This shelf doesn't consume much space, but is tall enough that it can accommodate a lot of stuff. It can be used strictly as a book shelf (although it may not be sturdy enough to hold lots of heavy books) or to hold a variety of items. I use it to store a variety of items that used to be on my desk. It's perfect for eliminating clutter.
In fact one unit is holding a large number of heavy books and does not appear to have been compromised at all by the weight. So hopefully this review is helpful to other people who might be looking for a similar set of shelves.
It looks more elegant than you would think for the price. it is pretty sturdy and can hold a decent amount of books. I tried shaking it and it held its ground. The shelf looks as pictured and is taller than 5'.
Once put together, this is quite nice. I wanted something with an open back so that I can use it with a printer and other electronics that have cords that need to go out the back to plug in. Also wanted to avoid the cheap IKEA type pressed wood style. I'm quite happy. It looks good with my small modern-ish TV stand.Oh, and the size is 64&#34; tall by 26&#34; wide by 11&#34; deep.
It's much lighter and gives my room a better look than the cheapest five shelf wooden bookcases. It can be easily put apart and put together again, which makes it even easier to be moved.The metal shelves look thin. I'll try fill the shelf with books to see what would happen when I have enough of them.
One person assembly, though may be faster with two in initial stage. Instructions consist of one page  expanded view of product and connections between parts in construction with list of parts and number each part included. One allen wrench is included and is only tool needed.A pointer is that the upper section slides over lower sections' tubing, and each section has holes connecting for last rod to hold sections together.
I adore the shelf, I truly do. It holds plenty of weight and fits exactly where I want it. The one problem I had is in assembly, while the instructions are good, you must be sure you are very careful of the holes. Else you will end up with the problem of needing to undo and flip round to make sure the supports are in the right place.
If there's one downside, it's that one of the shelves is a little lopsided, but it's not that big of a deal, and it might just be my carpet skewing things. Holds all my books well, and looks great - I would definitely recommend these.
Answer: Idk exact weight but my grAndaughter has it loaded with books it's still in Tact you won't b sorry it's worth every penny
