FAQs

What size crib sheet fits a US standard crib?

US standard cribs are 28x52 inches with a mattress up to 6 inches thick. These sheets are cut to fit that footprint with enough depth (up to 9 inches) for memory-foam and breathable-mesh mattresses. The elastic runs the full perimeter so the corners don't pop off at 2 a.m.

How often should I wash a crib sheet?

Weekly is the baseline. After any spit-up, diaper leak, or sick night, sooner. Tanboocel muslin dries in about two hours on low, which is why a two-sheet rotation usually holds.

Are muslin crib sheets safe?

Yes — with the standard rule that applies to any fitted sheet: it has to fit the mattress tightly with no excess fabric the baby could pull up. These sheets are sized to US standard cribs and the elastic is engineered to hold its grip through repeated washing.

Will these fit a memory-foam mattress?

Yes. The pocket is cut to fit mattresses up to 9 inches deep, which covers the thicker memory-foam and breathable-mesh mattresses most families are now using.
