This shelving unit was very easy to put together. I am not strong and typically not good at DIY but I was able to assemble this, no tools needed. You just twist the sections to screw them together. I did want somebody a bit stronger than me to check the tightness of my assembly as the shelving unit is slightly wobbly but it comes with a dowel to attach it to the wall to give it a little more security.

This shelving unit is not the sturdiest thing on the market, which is why I only gave it 4 stars and you couldn't put anything really heavy on it but it is fine for what I needed it for which is extra storage for books and small items.
