Sheet size finder
Fitted sheets fail on depth more often than on size. Enter your mattress and this returns the sheet size to buy and the pocket depth it must list — before you order a set that pops off the corners.
What to buy
A Queen fitted sheet with pockets of at least 12″
That is a standard-pocket set for a 60″ × 80″ mattress standing 10″ tall — the extra 2″ is tuck allowance so corners stay put.
Where to look: any set listing “standard pockets” and an explicit 12″-or-more pocket depth fits this mattress. Of the products assessed on this site, the Miracle Made® set lists pockets to 17″ in its manufacturer specification — details in the full review.
