The particle/flake board stuff doesn't do well during disassembly. The threads and bore holes for the various pegs that hold the boards develop cracks an begin to crumble. When you start applying force during disassembly the weakened particle board gives way and the pins pull out of the flake board. Spent half a day repairing a nice looking flake board Ikea book case a friend gave me when he moved. Half of the pins ripped out and two shelves split during disassembly. Wood glue and epoxy putty to the rescue.
