>Also the assembly for ikea stuff is usually perfect.. everything aligns to the last millimeter... which again, I can't say for much more expensive furniture pieces.
Probably because the ikea stuff you bought tend to be particleboard and the "expensive furniture pieces" are solid wood. Solid wood tend to wrap/deform more due to moisture than particleboard, which means even if they're drilled with millimeter precision at the factory they end up not aligning when it reaches your house. From personal experience the solid wood furniture I got ikea were definitely not aligned "to the last millimeter".
