The problem I've had with Ikea furniture over the years is that while it is cheap, functional and even stylish, in my experience it seldom survives moving to a new home intact.
It depends on what you get... Anything made of particle board "laminate" is garbage. IKEA, however, has quite a few lines of furniture made from real, solid wood (usually pine), which will last a surprisingly long time. We've got a television stand, a dinner table (with chairs), and a complete bedroom set that were all purchased from IKEA more than 10 years and two moves ago. Aside from the usual nicks and bumps from kids and pets, they're in very good shape.
Better yet, two clear pieces of plexiglass, so you can put your custom (and non-custom) maps in between and not have to worry about drawing on them.
