I did this one I have back ache all the time if it isn't

As usual, items of this nature from China have rather poor QC, the holes aren't drilled cleanly, the plastic tape on the shelf edges comes undone, and the instructions are very minimal, I think someone who isn't at home with tools and hardware would have a tough time putting it together without a lot of swearing.

I had a hard time assembling it: holes not big enough; nails not adjusted to the material

Not worth the bother to me and my time to return or even complain about, but I will write a poor review; shame on Amazon for selling such a cheap and poorly packaged product
