Description

Breathable, soft, and gets better with every wash: the Loulou Lollipop Muslin Fitted Crib Sheet keeps a baby comfortable all night, every night, without the overheating risk of a heavier fabric. The open-weave construction naturally regulates temperature to help prevent overheating during sleep, a genuinely important safety consideration for anything a baby sleeps directly against for hours at a time.

Made specifically with standard U.S. crib and bassinet sizing in mind, so there's no guessing about mattress compatibility. Available across the full range of Loulou Lollipop's hand-drawn prints, so a crib sheet can be matched to a swaddle, sleep bag, or quilt in the same design for a coordinated nursery look.

Why We Love It

Soft & Breathable Fabric

Made from bamboo cotton — naturally breathable and gentle on newborn skin.

Perfect Fit

Designed to fit all standard crib mattresses

Comes With a Reusable Drawstring Bag

Packaged in a reusable, matching drawstring bag for easy storage and transport

Designed for Deeper Sleep

Soft, breathable fabric keeps your baby at the right temperature all night long.

The Details

Fit. Sized to US standard cribs (28 x 132 cm / 52 in, up to 23 cm / 9 in of mattress depth). Elastic runs the full perimeter — corner-only elastic is how a sheet pops off at 2 a.m. and ends up bunched under the baby's leg. The deeper pocket also fits the thicker memory-foam mattresses most parents are buying now.

How many you need. Two is the minimum, three is the answer: one on the crib, one in the wash, one to absorb a sick night without a midnight dryer run. The open weave dries in about two hours on low, so the rotation actually works.

Materials & Care

Irresistibly soft, airy, and breathable, our muslin is called Tanboocel. It's made from bamboo tree pulp through a manufacturing process that uses 99% less water than conventional cotton.

FAQs

What size crib sheet fits a US standard crib?

US standard cribs are 28x132 cm / 52 in with a mattress up to 15 cm / 6 in thick. These sheets are cut to fit that footprint with enough depth (up to 23 cm / 9 in) to wrap securely. 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® Bamboo Viscose dries in about two hours on a low dryer setting, which is why a two-sheet rotation usually holds.
Are muslin crib sheets safe?

Yes — with one rule. The fitted sheet has to fit the mattress tightly with no excess fabric the baby could pull up. These sheets are sized to US standard cribs specifically, and the elastic is engineered to hold under repeated washing.
