SNOO Silk Sheet was specially designed by Happiest Baby to ensure a safe, snug fit on SNOO’s bassinet mattress. While our silk sheet wasn’t created with other bassinets in mind, it may fit a mattress with the same dimensions as SNOO (77cm x 35cm x 2.52cm).

Our Silk SNOO Sheet is made from 100% Mulberry silk, which isn’t as naturally stretchy as cotton fabrics. Because of this, the sheet is designed to fit snugly and may feel tighter than our Cotton SNOO Sheet—especially the first time you put it on. This ensures a safe, secure fit on SNOO’s mattress. If it feels like a tight squeeze when you put it on your mattress, that’s totally normal! Just line up the seams of the sheet with the sides of the mattress carefully and then smooth it into place.
