Advanced Technology

Give your little one the gift of cool, chemical-free sleep.

The Celsius Crib Mattress pairs certified organic cotton softness with high-tech Glacier cooling yarns that whisk away extra heat, making sweaty nap times a thing of the past.

Inside, Bundle Fiber with memory technology delivers airy support without a hint of foam, latex, or harmful VOCs.

One flip takes you from an extra-firm infant surface to a slightly plusher toddler feel, meaning the same mattress grows right along with baby.

Completely breathable, water-repellent, and hypoallergenic (and backed by a limited lifetime warranty ), this 6-inch profile nestles neatly into any standard U.S. crib so parents can rest easy, too.

100 % Breathable Core

Allows fresh air to circulate, reducing overheating and suffocation risks.

No Foam, No VOCs

Eliminates off-gassing worries for a purer nursery environment.

Edge-to-Edge Stability

2-inch perimeter support keeps little explorers safer during stand-up moments.

Key Mattress Benefits

5 Layers
Of Cooling
Comfort

A certified organic cotton and Tencel blend forms the top sleep surface. It feels soft against the skin while remaining breathable. Glacier cooling yarns actively pull heat away from the body. This helps keep the baby cool and dry throughout sleep.

A gentle water-based finish sits just beneath the cover. It enhances temperature regulation on the infant's side. This layer helps maintain a fresh and sweat-free surface. It supports more comfortable sleep during warmer conditions.

A reversible design provides two firmness levels within the same mattress. One side delivers extra-firm support for infants. The opposite side offers a slightly plusher feel for toddlers. This allows the mattress to adapt as your child grows.

A foam-free Bundle Fiber core forms the main structure of the mattress. It allows continuous airflow throughout the entire interior. The core contours gently while staying breathable. This supports comfort without trapping heat or chemicals.

A high-density perimeter edge surrounds the mattress. It provides added stability along the borders. This support helps toddlers stay balanced when standing. It also improves durability and prevents edge sagging.

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

Yes. Cooling yarns plus a water-based finish actively pull heat away from the baby for a steadier sleep temperature.

The cover is water-repellent, meaning small spills bead up for easy wipe-off. A separate protector is recommended for full waterproofing.

Each side is calibrated differently: an extra-firm infant surface promotes safe spinal alignment, while the flip side adds plushness for toddlers who need a bit more give.

Organic cotton is grown without harmful pesticides and feels naturally soft. While no fabric guarantees better sleep, many parents prefer it for reduced chemical exposure.

With dimensions of 28 × 52 × 6 inches, the Celsius fits all standard full-size U.S. cribs and toddler bed frames.
