Pretty expensive but it is very comfortable. I just swaddle my baby give her, her pacifier and lay her down and she falls asleep. She takes great long naps on this mattress. I like that it has a cover that you can take off and was. Fits perfectly in my mini crib. No space between the mattress and crib so don’t worry about her getting stuck in between them.This mattress is a winner! It fits perfectly in our Babyletto mini crib. The baby loves it and has slept so soundly since the first night we put it in his crib!Great mini crib mattress. Fit snug. Mini crib sheets are a little too snug so I used regular and tucked them very tight.This item fit my mini crib perfectly. The mattress feels comfortable, yet firm.Only complaint: I wish the firm and soft sides were labeled. It is a bit tough at first to determine which is which.I didn't think a baby would care about a mattress until I laid him down on his cheap crib mattress and he started shrieking. The only place he'd sleep was in his swing or on our thick exercise pad. He apparently likes a thick, firm, squishy mattress and this was the thickest, firmest, squishiest mattress I could find. He's 10 weeks old and he sleeps 11 hours straight on this thing at night. Plus, this mattress seems perfectly safe. I can't imagine how he'd smother on it, even if he flipped over onto his stomach. It has some squish, but not enough squish to block an airway. The price made me cringe, but the toddler side ensures we'll get a few years out of it. Telling the infant side from the toddler side is tough, so I marked one side with a permanent marker.And since you're reading reviews, I assume you're dealing with a baby who won't sleep well, so I'm going to recommend two other products that are great for that: a book by Suzy Giordano called the Baby Sleep Solution and this one baby soother that is heart-shaped, plays sushing noises, projects stars onto the ceiling, and has a cry sensor. With all three, he's now sleeping great.My baby sleeps great and the firmness has held wonderfully so far. I would definitely recommend.I bought this and the Newton and as a first time parent I really really wanted to love the Newton. I mean if you can afford it why not but If you’re in a budget go with this one! My baby will be one next year and we keep this mattress in his play pen.This was a GREAT mattress…for six months. The center of the mattress is now sinking in and starting to make a very visible canoe shape without my baby even in the crib. I know it is dual sided, but I did not intend to need to flip the mattress over before my child was 12 months. For safety, I need to replace it. It should last 1 year for the price, but did not.I mean, it’s great that our daughter sleeps well with this mattress, but a quick search on Baby’s R Us shows a full size mattress is anywhere from $99-199. Not sure why a smaller size mattress is more expensive, but okay I guess.Also, when we told a few friends about the price, every single one of them said “wow, that’s expensive”, which is what made us look at other stores to compare.Either way, our daughter sleeps well in it. What I’d recommend is you shop literally anywhere else first to make sure you don’t pay up to 2.5x the cost of what it should be, like we did :/First night on this my baby woke up only three times vs six times cosleeping with and also her Bassinet. Is it the mattress? I think so! Her naps were actually better today too. I hope this continues so she can get more rest. Only 1.5 days into it but I love the mattressInitially loved the feel and quality of the mattress however my baby’s back was consistently really hot feeling after a period of sleeping for 2 hour stretches. Despite being dressed in merino wool Sleep sack and appropriate room temp (20 deg). This doesn’t happen when he co sleeps with us so it has to be the mattress. Disappointed as it’s advertised as breathable and high quality as well as at a premium price point.Baby isn't using it yet but seems very comfortable.Abit expensive thought, but it fits my mini crib da Vinci.I would recommend.High quality mattress, its light and durable. Baby sleeps very good in it, It has 2 sides, for infant and the other for toddler. Very satsfied with this purchase.
