Crib Sheet in Tanboocel® Bamboo Viscose - Astro Explorers

Soft, breathable bedding that does not trap heat — fewer wakeups from a hot, damp mattress, and more unbroken sleep.

Rockets, astronauts, UFOs — and one very small space explorer about to fall asleep.

A crib sheet has to do three things well: tuck tight and stay tucked, dry fast enough that a two-sheet rotation actually works, and look good enough to earn its place on the registry page. This one is built for all three.

Material. Tanboocel® Bamboo Viscose, blended with cotton and woven into open-weave muslin. Tanboocel® is a branded bamboo viscose made through a closed-loop process — third-party verified, with a lower water and chemical footprint than the generic bamboo rayon most brands quietly label "bamboo." It gets softer after the fifth wash than on day one, the opposite of how cotton ages.

Fit. Sized to US standard cribs (28 x 52 inches, up to 9 inches 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.

The print. Soft pink ground with multicolored rockets, astronauts, flying saucers, planets, moons, and small stars.

Care. Machine wash cold and tumble dry low. Tanboocel® takes the dryer better than bamboo rayon, with less pilling and shrinkage over time. Don't bleach; iron on low only if you need to.

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.

Adjacent products. Pair with a matching muslin swaddle for the newborn months or a 0.5 TOG muslin sleep bag in the same print for a coordinated registry set. The Newborn Gift Bundle includes coordinating pieces at 15% off.

Safety & certification. AAP safe-sleep compliant. Tested to CPSC, CPSIA, and ASTM standards. Material certified to OEKO-TEX Standard 100. Loulou Lollipop is a Certified B Corporation.
