Guide for fitting - We recommend allowing an extra two inches on the depth of the sheet to ensure that the sheet tucks right under the mattress. For example; If the exact depth of the mattress is 8" then we recommend a fitted sheet with a 10" Box If the exact depth of the mattress is 10" then we recommend a fitted sheet with a 12" Box All sheets are machine washable at 40 degrees and can be tumble dried.
