Bunk bed is very sturdy.  All the pieces & hardware were well-packed in 3 separate boxes.  I was able to install most of it by myself but needed help when it was time to life the top bunk onto the bottom bunk.  It was easy to follow instructions and the end product is just as described.  The trundle rolls well on the wheels. 

I have 9 ft ceilings, so the tall twin feature works well for the room.  No one bumps their head on the top bunk or the ceiling when sitting up.

 I highly recommend this product.
