I spent a lot of time researching this purchase and am mostly very pleased.  I wanted a ladder that is attached and sturdy, not one that hooks on and therefore moves around as kids jump up and down it getting in and out of bed.  This ladder is very sturdy.  Also I can fit a full size bed underneath (perpendicular) for my other child.  I also liked that it has a lot of support for the mattress, not movable slats that can fall out.  I took off one star because the hardware didn't match up to all the holes, leaving one important bolt missing at the end so it was wobbly and had to be reinforced with an extra slat not provided.  Probably with the bolt it would have been plenty sturdy enough.  

Pros: Ladder is attached; lots of support for the upper bunk, roomy underneath.
Cons: Hardware didn't match perfectly.
