Simmons Kids SlumberTime Naturally 4-Inch Mini Crib Mattress

I researched mattresses for a long while before buying this one from my babies mini crib. now that I have bought this, I really love this mattress and my baby sleeps as good as ever.My only complaint, initially, was that I was delivered a mattress that was previously sent to someone else and opened. I returned that one and bought the one I have now, which was delivered new the second time around.

Quality made and soft and waterproof

The tag for this mattress says that it is "100% polyester".Waterproof cover is made of nylon (vs others made of unsafe vinyl).No fiberglass for flame retardant.Weave-like feeling. Kind of similar to Newton Baby's more expensive mattress when pressed down.Upon arrival, I aired the mattress for a day since it was sealed in a plastic cover. After 24 hours, the smell was pretty neutral.No BPA or polyphenol fumes as you would encounter with memory foam mattress on the market.I use an ikea waterproof pad, a mattress cover, and thin cotton sheet. My baby sleeps soundly and goes down for naps faster with this new mattress. I press down on it with this setup and wonder why I didn't buy this in the first place. For the pricepoint, baby's demonstrated comfort, and baby-safe safe materials used, I give it 5 stars!

This mattress is a great buy. It is comfortable for my baby to sleep on. It fits perfectly in the mini crib with no side gaps. The mattress seems very solid not flimsy or too plush, I think it will last for years until he outgrows it.

This could have been a good mattress, with a firm surface and seemed breathable for infant. Unfortunately the first mattress I ordered came with a manufacturing defect (fabric bunched up on the side and sewn up that way) and was also uneven, with a gap more than two-fingers-worth on one end. My mini-crib is made by the same company, Delta. The replacement that Amazon sent arrived in a much too large Amazon box and was otherwise unpackaged... no plastic bag or informational inserts, and so it was likely used. I tested it for gaps anyway, and it fit even worse (gaps on both ends). This time, I let Delta know about the issue with the Amazon mattresses and asked them to send me one from their factory instead, or to work with Amazon to ensure that I was sent a new mattress without defects. They responded more than a week later and required a mountain of documentation. At that point I cut my losses, returned the second mattress, and decided to upgrade to a nicer mattress by a different company.

Fits our Mini Crib nicely. DaVinci Kalani. I looked through a ton of reviews before purchasing and couldn’t find one that said it fit so I took a chance and I’m glad I did. Great price for a mini crib mattress. Doesn’t have any smell - not sure what the other reviews are talking about.

My son has been using this mattress for many months and turly it's good quality, Firm, yet soft. My son enjoys it and I'm happy.

I purchased this mattress for my delta mini crib about 4-5 weeks ago, ironically around the time that my son was having his 5 month regression and this thing saved my life haha!He sleeps 9-10 hours waking once to feed (he’s 6 months) which tells me that he’s comfortable. The mattress is firm but I wouldn’t say it’s hard. We do have a mattress pad on top for waterproof purposes but regardless I think he likes it.It fits our delta mini mattress perfectly so he’s able to stay in our bed for a little bit longer before transitioning him to his own room. With that said I actually like the firmness of the mattress because it’s identical to the delta mattress I have for his full size crib so I think it will make the transition much easier for him.All in all great purchase

Esperaba que fuera mas suave-blando pero al contrario, el colchón es un poco duro.
