I like that its not very tall, kids don't have trouble getting in/out.  Our twin mattresses were slightly thicker than the picture, but guard rails still function as intended.  There were a few warped pieces bur they assembled fine, it took about 1-2 hours to assemble with my twins "helping" me misplace bolts.  It should be in the mid $200 range based on the quality of parts, none of the wood pieces are very thick.
