Query: A little Small for the Emily 4-in-1, Seemed like poor quality

It was a little small for the Davinci Emily 4-in-1 crib (I had ample space to move my hand around between the mattress and the crib). I feel the quality just wasn't there as well. It is a foam mattress which tend to fail and create gaps between the mattress and the crib. Given the price tag, I would have expected it to be a much better quality. I returned this for the Serta Perfect Sleeper. The Serta mattress has a 30 year warranty for the same price vs. the MDB 5 year limited warranty. I plan on this mattress being used for several children and to be used once the Emily is converted into a toddler bed, so I wanted a better warranty, and a higher quality mattress that fit correctly in the crib and would last.
