A bit lower than I had expected. Was not quite as easy to put together as I had expected. The quality of the metal seems good, but the bolts that were provided were almost too short for the  pre-drilled openings.  And the plastic bits that are provided to hold the rails in place are a bit difficult to insert, and seem kind of flimsy.  I am hoping this will stand up once it is actually slept on by a teenager or an adult.  The wheels roll nicely.
