This luxurious 100% cotton "woven" portable / mini crib sheet features primary colorful pindots on a solid black background. Our sheets are made of the highest quality fabric that's measured at a 280 tc. That means these sheets are soft and durable. 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. Size: 24 x 38.Note: Please make sure to select the proper fitted sheet for your mattress size. There are two different depths available. If you have the standard 3 inch thick mattress, then make sure to select 61 cm x 99.1 cm x 7.6 cm ('24 inches x 38 inches x 3 inches'). If you have the extra deep 14 cm (5.5 inches) or 15.2 cm (6 inches) mattress you will need the extra deep fitted 61 cm x 99.1 cm x 14 cm ('24 inches x 38 inches x 5.5 inches') size sheet.
