As described. We got for my toddler who is getting ready for a toddler bed, but in case he looses privileges, we can put the tall rail back up.
The lowest level of the crib is LOW. It sits about 5-6 inches off the ground, which is handy for my preggo belly since our last crib was a Bratt Decor and super tall. 
Also this was the only crib we saw for a decent price that also included the shorter toddler rail, so you don’t have to purchase that separately which is nice.
