DK Glovesheets have been making fitted sheets since 1950. They are still made in their family run factory in Surrey, using only top quality yarns, to ensure you receive exceptional products for your baby. The Fitted sheets are made from 100% jersey Cotton and offer exceptional quality. They will retain their shape and softness for years to come. The original sheet design still fits the mattress better than other fitted sheets. The deep corners and elasticated edge keep them firmly attached to the mattress, without slipping or rucking. Glovesheets are made from top quality 100% combed cotton interlock, which is far stronger than single-jersey material used by most other manufacturers, and will last for much longer. It is thicker, and softer to lie on. Machine washable at 60 degrees. Designed to fit mattresses between 69-71cms x 140-144cms
