Safety Built Into Both Sides

Features a flippable, two-sided design developed with pediatric sleep specialists and parents, and built to the American Academy of Pediatrics' firmness guidance for safe infant sleep.

A Flippable Design, Newborn Through 3 years+

Infant Side

What it is

A flat, extra-firm sleep surface for newborns to ~12 months, made from fiberglass-free, Greenguard GOLD, and CertiPUR-US certified foam, hand-crafted in our Arizona facility.

Why it matters

Meets the American Academy of Pediatrics' firmness guidance for safe infant sleep with an extra-firm surface that keeps its shape, which infants need before they can reposition themselves. Covered in our breathable, 100% waterproof Easy Airflow Cover for heat regulation and safe sleep. Talk to your pediatrician about when to flip sides.

Easy Airflow Cover

What it is

A 100% waterproof and machine-washable cover.

Why it matters

Air can move freely through the honeycomb weave for temperature regulation, while full-coverage waterproofing keeps accidents out of the core, plus it's machine-washable, so everything inside stays clean and dry. No extra protector needed.

A Flippable Design, Newborn Through 3 years+

Toddler Side

What it is

Firm, fiberglass-free foam certified by Greenguard GOLD and CertiPUR-US, crafted in our Arizona facility to support years 1-3+.

Why it matters

Provides appropriate comfort and musculoskeletal support as they grow, with the same breathable, 100% waterproof Easy Airflow Cover, so protection never changes when the feel does. Move to a big-kid bed when they start climbing out of the crib; your pediatrician can confirm when it's time.

The 2-Minute Crib Reset

Don’t let diaper blowouts ruin your night. Unlike covers that protect only one side, our full-coverage waterproof design keeps every accident out of the core and gets everyone back to bed in minutes.

1️⃣ Unzip the dirty cover

The full zip-off design comes off in one easy motion.

2️⃣ Zip on a clean cover

Keep an extra cover on hand so there’s always a clean one ready.

3️⃣ Toss the dirty one in the machine

It's clean and ready for baby.

100% Waterproof. Magically Still Breathable.

Most waterproof covers trap heat. The Easy Airflow Cover stops water but allows air to flow.

Seals out every drop

360° waterproofing on all sides keeps liquid out of the core, helping prevent bacteria, mold, and mites that can irritate little lungs.

Lets air flow

A 3D honeycomb weave opens ¼″ air pockets across the surface so heat can escape and air can circulate, keeping your baby at a comfortable temperature for fewer wake-ups.
