So, we have a 4x4 in ds's room. I built it and secured it to the wall about 2 years ago. We are now rearranging the furniture in the house a little, and considering moving the Expedit to the loungeroom. Dh thinks it doesn't need to be secured to the wall and thinks it is unnecessary and will only ruin the wall. I strongly disagree and told him I would rather dispose of it than have it in the house unsecured.
While ds knows not to climb it, I have caught him out once or twice before. The cubes make it very easy to climb. The thought of it falling on ds makes me sick.
I noticed that some people in the other thread have it unsecured... Does it make you nervous? Do your children ever climb it?
