I ended up replacing the two middle center columns. Most of the card is made of the harder mdf board. Those columns were made of chipboard that crumbles. I ended up replacing those. It took like 3 weeks and many hours to put it together. Also the manual isn't right. Luckily I'm an engineer and I was able to figure it out. I love the color of it. It matches my cabinets. The drawer slides work great. If they would use the same mdf on the whole thing, it would be a much better product.
