I heard mixed opinions about making cupboards and beds from MDF. Some said it doesn't matter, MDF is as durable as whole tree or sandwich boards. Some said that MDF is weak, and will not last for years if you move the MDF-beds often.
I'll be glad to hear your experiences about the durability of the MDF.

I have used MDF for a number of furniture building applications. Shelving, cupboards, cabinets (body and doors).
Overall, it has some advantages and some disadvantages. I think it is rarely the best material, but probably good enough for a number of furniture building applications. And for some things (like cutting into shapes with a jigsaw) it is very handy (no grain). I have not so far had any serious durability issues, but I do always take the above precautions.
