Overview

Designed specifically for Stokke Sleepi V2 and V3 cribs, the Naturepedic Breathable Organic Oval Crib Mattress gives families a better organic mattress option for Baby’s unique crib shape. It’s made with firm support, certified organic materials, waterproofing, and a removable, washable, breathable layer, all to help to support airflow while keeping cleanup simple.

An Oval Crib Mattress to Fit Your Favorite Crib

Support for Stokke Sleepers

A stable sleep surface in the crib style you love. Meets AAP and CPSC guidelines for firmness and fit — designed specifically for Stokke Sleepi V2 and V3 cribs.

Waterproof and Breathable

Uniquely designed with a removable breathable layer over seamless waterproofing, so airflow and easy cleanup can work together. No need to compromise.

Certified Organic, Inside & Out

Made only with certified organic cotton and GOTS-allowed accessory materials — no polyurethane foam or flame retardants, ever.

How the Breathable Organic Oval Crib Mattress Works

1. Air Moves Through the Surface

A removable breathable layer creates space for 360 degree airflow between your baby and the mattress, helping to reduce trapped heat and moisture at the sleep surface. Back sleeping is always safest for Baby, but in case they do roll over, they can breathe right through the mattress surface.

2. The Mattress Stays Protected

Underneath, a seamless waterproof surface helps to prevent accidents from soaking into the mattress. This is essential. If a mess contaminates your mattress core, even "washable" mattresses, it's nearly impossible to clean. (And most "washable" mattresses are nearly impossible to dry.)

3. Clean Up Is Easy As 1-2-3

When accidents happen, simply remove the mattress cover (which conveniently has a waterproof backing for extra protection), wipe the mattress clean, and put Baby back to bed. No need to hose down your mattress (or worse, shower with it). 

Why Parents Love the Breathable Organic Oval Crib Mattress

No Compromise Design

Love the look and function of the Stokke Sleepi? Our Breathable Organic Oval Crib Mattress is designed specifically for Stokke Sleepi V2 and V3 cribs, so you don’t have to choose between the crib you want and the organic mattress standards you care about.

Lightweight for Easy Lifting

Designed with a lightweight core, this oval crib mattress is easy to lift, move, and maneuver when it’s time to change sheets or clean up after everyday messes. It’s practical support made for real-life routines.

Seamless Waterproofing

A smooth, seamless waterproof surface helps to guard against messes, which is a must for breathable mattresses. Made from non-GMO sugarcane, this waterproofing material keeps cleanup simple — no phthalates or vinyl/PVC required (two common sources of PFAS, aka “forever chemicals”).

What’s Inside the Breathable Organic Oval Crib Mattress

Cover made with organic cotton, polyester lattice, and GOTS-allowed TPU waterproofing for breathability. 

Organic cotton surface with PE waterproofing made from non-GMO sugarcane for hygiene.

Plant-based PLA firmness support layer for structure.

Texas-grown organic cotton batting for comfort.

WaveSupport™ core made from GOTS-allowed PE for innovative, lightweight support.

Simpler, Better Materials

Before it becomes an oval crib mattress, it starts here. Cotton. Non-GMO sugarcane. These materials are selected with your baby’s health and safety in mind.

Organic Cotton

This mattress is super cozy, but not too soft for babies. Fits the Stokke Sleepi perfectly. And love feeling safe knowing it's made from only clean materials.

Alan, Verified Buyer

Well made and will last for several years! Love that it's lightweight too for easier sheet changes.

Carmen, Verified Buyer

It gives me some peace of mind to know Baby isn't being exposed to questionable materials, especially when you consider how much time they spend in their crib over those first months and years.

This results in a healthier, more sustainable fabric that minimizes exposure to toxic chemicals.
