This luxurious 100% cotton "woven" portable / mini crib sheet is 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. Color is a solid dark grey. 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 '24 x 38 x 3'. If you have the extra deep 5.5" or 6" mattress you will need the extra deep fitted '24 x 38 x 5.5' size sheet. The extra deep sheet works with brands such as the 'DaVinci extra deep mattress' as well as some other brands.
