Furniture barricade

Hi! I love games in which I can use furniture to barricade my safehouse but in Cataclysm furniture is sooo heavy and I can’t move it. I can use only crates because zombie can’t go through this. I know that refigerator or sink is heavy but this is too much in my opinion. What do you think about this?

Bookcases and lockers are easier to push if I recall, but they’re also not as sturdy. If we had a way to reinforce certain furniture in the same way we can board up and otherwise enhance doors and windows…
