I'm a new grandma and this is perfect for my spare bedroom.  Easy to put together (it was missing a washer but easy to find at the hardware store). I did but another mattress as recommended by others.  The one that comes with it is more of a pad like what you'd find in this portable,  pop-up beds.  It works with a dust ruffle as well.  I love that it folds away for times I want it out of that bedroom.  My grandson is 4 months old and slept great with room to grow.
