@dalybrady Target Sealy Butterfly 2- Stage Crib & Toddler Mattress I received these products for free from the Hey, Bullseye sampling program in exchange for my honest review. Target and #heybullseye #ShareMyTargetStyle The Sealy Butterfly 2-Stage Crib and Toddler Mattress is a must have. It arrived vacuumed sealed inside a box. Open the mattress and it starts to expand. Per the directions it says to let it expand for 48 hours. The mattress is a firmer high density foam side for the infant and a more comfortable soybean memory foam side of coziness for the toddler. The sides are identified on the sewn tag of the mattress. I like that the mattress comes with a waterproof zip off cover to keep the mattress dry from any accidents. The cover is breathable and fits the mattress snugly. Fits snug in the crib. I absolutely recommend this mattress. The mattress is Hypoallergenic. It measures 52 x 28 inches. A quality mattress that is perfect for the little one. Another perk to the mattress is that it is made in the USA!
