Which Kind Of Wood Must Suitable For Built In Wardrobe?

[archenemy 0]

just checking what materials are commonly used in making built in wardrobe..

i have a bad experience with my current(my parents house) built in wardrobe..less than 1 month..the peg which a board sits on broke...you know the kind where they have a short metal pin...plug into the holes which are on the wardrobe sides?

upon closer inspection, i found out that the wood is actually those kind of compressed wood chips..**** soft and useless!

which kind of wood board is stronger?
