Because our child is in the small bedroom, we needed to maximize the space.  This bed was easy to construct with two adults and the included allen wrench(es).  We were able to build it in about an hour and a half.  The integrated desk is very solid and serves it's purpose well.  The ladder affixes to the frame, so there is less risk of falling.  There are 13 slats holding the mattress, which are screwed down - which offers a lot of support!  Be prepared to have to tighten all the screws occasionally, because it will begin to have some play in it over time. As my child has grown, the bed has started to rock more because of their weight.  I'd say it is ideal for the 8 to 13 age range.  Overall, we are very pleased with the bed, it's construction and the directions.
