This mattress is excellent! I ordered this for my son last year in December 2009, and a year later it is still in excellent shape. That has been a pleasant surprise (durability) since at the time I didn't know my son would turn out to be such a little Tazmanian devil LOL! . For an active 9 month old boy it is still holding up well. He sleeps extremely well in it. We loved it so much that we are going to order this as a gift for our newborn niece. Excellent price for a durable safe mattress what more do you want. BTW we got this in quick (3days) from ordering.
