Overview

The 2-in-1 Organic Kids Mattress is a flippable organic kids mattress designed to grow with your child. One side features waterproof protection for potty training, while the other offers quilted comfort for older kids ready for a more grown-up feel. (And both sides are firm enough to support proper growth and development.) This nontoxic kids mattress is made with certified organic materials — and without polyurethane foam, flame retardants, vinyl/PVC, or fiberglass. It’s a smarter organic twin mattress for growing kids.

The Organic Kids Mattress That Grows With Them

Waterproof Design Made for Potty-Training

Non-GMO sugarcane PE waterproofing protects against accidents. No extra waterproof pad needed (and no extra chemical concerns like vinyl/PVC or phthalates either).

One Mattress, Two Different Feels

Sleep on the flip side! Start with the waterproof side for potty training, then flip to the comfier, quilted side when your child is ready for a more grown-up feel.

Certified Organic Materials, Inside & Out

This nontoxic kids mattress is made with organic cotton and plant-based PLA batting with a standard innerspring system — no polyurethane foam, glues, or flame retardants, ever.

Accidents Happen.

Do Kids Need a Waterproof Mattress?

Kids mattresses go through a lot, from potty training accidents to water bottles, sick nights, and everyday messes. A waterproof kids mattress stops liquid at the surface, because once moisture seeps past the sheets and into the mattress core, it can be extremely difficult to fully clean or dry. Over time, trapped moisture can lead to lingering odors, stains, and potential mold or mildew growth — not healthy for your growing child to be breathing in! Built-in waterproof protection can help keep kids mattresses cleaner, fresher, and better protected for years of use.

How a Two-Sided Kids Mattress Works

1. Start with the Waterproof Side

Use the waterproof side while your child is potty training. It protects the mattress against accidents and spills, so cleanup is easier when accidents happen. And, made without vinyl/PVC, phthalates, or PFAS (as the only UL Non-Detectable PFAS Validated kids mattress on the market), the materials are cleaner, too.

2. Flip to the Quilted Side

When your child is fully potty-trained and ready for a more grown-up feel, flip the mattress to the quilted side. It features a softer, more finished sleep surface while extending the life of your organic kids mattress through multiple stages (because they grow so fast!).

Because When They’re Sleeping, They’re Growing …

Firm Support for Growing Bodies

Kids need a mattress that promotes healthy alignment as they grow, not one that lets them sink too deeply into the surface. This kids mattress uses a firm design to help keep growing bodies properly supported through toddler years, childhood, and beyond. It’s a practical choice for parents looking for an organic twin mattress that’s comfortable but still feels stable and secure.

Allergy-Friendly Materials

Because young children may not know or show sensitivities yet, this allergy-conscious kids mattress is designed without wool or latex. It offers a simpler material profile for families who want certified organic comfort without two of the most common mattress allergens parents may be trying to avoid — at least until kiddos are a little older!

Sleeps Cool Without “Cooling” Chemicals

Kids can sleep hot, especially as they grow, dream, and squirm around at night. The 2-in-1 uses breathable organic cotton to help regulate comfort without the gels, foams, or questionable “cooling” additives you see in conventional mattresses. It’s an organic kids mattress designed to keep airflow clean and simple.

Organic Cotton
Plant-Based PLA
Nontoxic Waterproofing
Steel Innerspring

Organic Cotton

Naturally soft, breathable, and gentle on the skin, organic cotton promotes airflow and helps keep your sleep surface cool and comfortable.

Plant-Based PLA

Derived from non-GMO sugarcane, this fiber adds lightweight resiliency and helps wick away moisture for a fresher, cleaner sleep environment.

Nontoxic Waterproofing

A smooth, easy-clean surface made from non-GMO sugarcane PE protects the bed from everyday messes (and avoids phthalates and vinyl).

Steel Innerspring

Made in-house without glues or adhesives, this network of steel coils creates a stable base to maintain consistent support across the surface — essential for a child’s development.

I am very picky about making sure the least amount of toxins are entering my home, especially where my son sleeps. Naturepedic hands down is the best option when it comes to checking all the boxes for me.

Very comfortable mattress for my young child. Love that it has the waterproof side while we are still working on potty training.

2-in-1 Organic Kids Mattress Care Instructions
To care for your 2-in-1 Organic Kids Mattress, remove bedding and wipe the waterproof side clean with a damp cloth and mild soap as needed. Avoid soaking the mattress or using bleach/harsh cleaners, and always let the surface dry completely before replacing sheets or covers. For the quilted side, spot clean only and keep moisture to a minimum, since liquid that seeps into any mattress can be difficult to fully clean or dry. For best results, use the waterproof side during potty training or spill-prone stages, then flip to the quilted side when your child is ready for less built-in protection. We recommend adding a waterproof mattress protector to the quilted side of the mattress in case of accidents.

100-Night Risk-Free Sleep Trials
Sleeping is believing! That’s why we offer a 100-night, risk-free trial. Let your little one sleep on it, and if you’re not completely satisfied, you can return it within 100 nights for a full refund. We want you to find the perfect fit for their sweetest dreams.

Minimized Chemical Exposure
At Naturepedic, we minimize environmental impact and health risks by strictly avoiding flame retardants, phthalates, vinyl/PVC, formaldehyde, and other materials found in conventional mattresses and bedding. We adhere to strict, third-party standards and testing protocols and, in 2024, we became the first mattress brand to become EWG Verified®. View more of our certifications.

Organic Cotton
Certified organic cotton stands out as a safer choice for the environment, farmers, and consumers alike because it’s cultivated without synthetic pesticides or fertilizers, as prohibited by the Global Organic Textile Standard (GOTS). Organic certification ensures adherence to strict environmental and ethical standards, promoting biodiversity, soil health, and fair labor practices. This results in a healthier, more sustainable fabric that minimizes exposure to toxic chemicals.

Plant-Based PLA
Plant-based PLA (polylactic acid) is a fiber derived from plant sugars. Ours is sourced from non-GMO sugarcane. As a plant-based alternative to petroleum-derived synthetics, PLA helps reduce reliance on fossil fuels while offering a lightweight, resilient material that performs well in bedding applications. By using responsibly sourced plant inputs rather than conventional plastics, PLA supports a more sustainable material system while maintaining the comfort and durability expected in modern sleep products.

Glueless Encased Coils
Our encased coil system is engineered without the use of glues or adhesives, relying instead on precise mechanical assembly and heat-sealed fabric encasements. Each coil is individually wrapped to provide targeted support and reduced motion transfer, helping the mattress respond more accurately to your body. Made in-house using recycled U.S. steel, these coils reflect a more controlled, responsible approach to manufacturing. By eliminating adhesives in this critical structural layer, we prioritize material integrity, durability, and a cleaner overall design.

Sustainability in Every Stitch
Naturepedic has been honored with the Good Housekeeping Sustainable Innovation Award, the Real Leaders® Eco Innovation Award, the Clean Production Action’s Chemical Footprint Project Front Runner Award, the Environmental Working Group Hero Award, and others. We are a Green America Gold certified business and, as a 1% for the Planet® Member, Naturepedic donates 1% (or more!) of our annual mattress sales to environmental organizations driving change.

Responsible Packaging
Naturepedic’s packaging is crafted with Mother Nature in mind, featuring kraft paper roll-packing to reduce the need for plastic. We use environmentally safer soy inks, FSC® certified paper, cardboard with high recycled content, and local printing partners to help reduce our carbon footprint. Learn more about our packaging.

Naturepedic products are consciously crafted in the USA using a blend of high-quality domestic and global materials. By manufacturing here at home, we support local jobs and ensure strict quality control, while our carefully selected global materials help us create products that meet the highest organic and safety standards — plus, we’ve personally tested them so we know they’re oh-so-comfy!

GOTS-Certified Organic Factory

This means that our facility, located in Chagrin, Falls, Ohio, is inspected once a year to ensure it continues to meet the stringent standards for organic production, environmental management, and social responsibility.
