Great but don't forget to tap free Angi assembly.

Please don't forget to tap the free Angi assembly. I did and couldn't get it after the purchase. I noticed it 1 min after order and was too late. Even after talking to both Walmart and Angi rep. So I had to pay some one to assemble it. Looks great, sturdy granddaughter loves it for her newborn on the way.

Good low cost choice

True standard size which fit snugly in our two different cribs from two manufacturers. It's a lighter weight than our other crazy expensive “breathable” crib mattress, but I think it will hold up fine. That said, our grandkids are on the small side and don't tend to be rowdy jumpers—unless the newest 3 babies break the pattern! I'll try to update this review as this mattress gets more use.

Baby shark snore, snore snores

Product is simply amazing. It was so easy to assemble and our son absolutely adores it to anybody transitioning from getting their kid to sit in their big boy bed and stay in it. Here's your item.
