Now that this shelf is up, I do like it as I have a huge asymmetrical cubby on the floor. 
I’ve put together a lot of pieces of furniture. From cabinets, dressers, night stands, TV stands, I’ve seen all levels of difficulty. What looks like a relatively easy shelf was very difficult. I know directions are usually less than perfect on this type of thing, but these seemed flat out wrong. I could not eve visualize what they were trying to have me do.
