This crib fit our nursery perfectly and can be easily assembled with 2 people. Once assembled, the mattress fits on it snuggly. There are at least 3 height adjustment, and we opted for the highest slot initially for our newborn. This height position will save your back for days! One nick pick is that, with how the mattress hinge system, it can tilt 1 degree forward or backward. Not sure was that just how it was designed. But either way, our newborn was not affected and you can barely notice. I would still recommend this was this crib is worth every penny with its aesthetic, construction, and safety.
