I was the one who said bookshelf (no edits were made). I made it out of planks of wood and wood screws. The Ikea bookshelf uses wood planks but of a lighter/less durable kind of wood. I'm sure mine might have held up cast iron books where the Ikea version would have failed, but as a regular bookshelf for paper books, the price/performance of the Ikea product would have met my needs more than adequately at a decent cost savings.
