I bought two of these beds for my granddaughters that are 20 months and 22 months.  The girls love their big girl beds.  The only adjustments that my husband and I made were to put both of the side rails that have a hole for the guard rails on the same side of the bed.  We have the guard rails at each end of the bed.  Leaving an opening in the middle. We put the other side up against the wall.  The guard rails are a little short and putting them on the same side makes it a smaller opening for them to not fall out.  The support board in the middle is sharp and we were worried about them scratching themselves getting in and out of the bed, so we put rubber corner pieces to cover the edge.    This is our first week with the bed, so we will have to see how well it holds up to two toddlers.
