This luxurious plush 100% cotton "jersey knit" sheet is made of the highest quality fabric that's measured at 150 gsm (grams per square meter). That means these are softer than your favorite t-shirt, and as soft as flannel. Sheets are made with deep pockets and are elasticized around the entire edge which prevents it from slipping off the mattress, thereby keeping your baby safe. These sheets are so durable that they will last all through your baby's growing years. We're called sheetworld because we produce the highest grade sheets on the market today. Color is a solid black. Not a BabyBjorn®product. Sheet is sized to fit the BABYBJORN® crib. BabyBjorn® is a registered trademark of BabyBjorn AB.
