Naturepedic 2-in-1 Kids Review: Buy It for Potty Training

The Naturepedic 2-in-1 Organic Kids Mattress is a flippable organic kids mattress built to grow with your child, and its main reason to buy is simple: it is the only certified organic and waterproof kids mattress on the market. One side carries a waterproof layer for potty-training years, the other flips to a quilted big-kid surface, and both sides stay firm enough to support growing bodies. If you want certified organic materials without polyurethane foam, flame retardants, vinyl, PVC, or fiberglass in your child’s bed, this is the model to look at first.

This review is part of our guide to the best mattresses for kids, where the strongest models are compared side by side.

Who is the Naturepedic 2-in-1 Organic Kids Mattress for?

This mattress is for parents of toddlers and young children who want a certified organic, nontoxic sleep surface with built-in waterproof protection. It suits families in the potty-training stage, families managing allergies who want a sleep space made without latex or wool, and parents who would rather flip a mattress than replace it when the child grows. The flippable design means one purchase covers both the little-kid years and the big-kid years.

It is a strong fit if you are furnishing a twin or full bed, a trundle, or a shorter trundle frame, and if firm support matters more to you than plush contouring. Naturepedic describes the feel as extra firm, and both sides are firm enough to support proper growth and development. That makes it a sensible pick for back and stomach sleepers in childhood, and for parents who have read that kids need a surface that keeps growing bodies properly supported rather than letting them sink too deeply.

It is a weaker fit for teenagers who want a softer, more adult feel, for shoppers working to a tight budget, or for anyone who needs a mattress without a firm lean. In that case, look at the adult options in the brand’s lineup, such as the Naturepedic Serenade, or compare the wider organic category in our Saatva vs Naturepedic comparison.

What sizes and prices does Naturepedic list?

Naturepedic lists four sizes for the 2-in-1 Organic Kids Mattress, with prices from $699 to $999. The twin is the entry point for a standard kids room, the trundle sizes cost less because they are shorter and thinner, and the full is the step up for older children or larger rooms. Here is the full price and specification table as published on the product page.

The listed weight limit is a product specification, not a recommendation about what any child should weigh. Naturepedic also offers optional foundations and legs alongside the mattress: a Deluxe Organic Bed Foundation in twin sizes is listed at $499 for the standard 8-inch version and $399 for the low-profile 1.5-inch version, with foundation legs at $149 for 7-inch legs and $139 for 5-inch legs.

How does the two-sided design actually work?

The two sides do different jobs. The little-kid side carries food-grade PE waterproofing derived from non-GMO sugarcane, which is the surface you use through potty training, water bottles, sick nights, and everyday messes. Flip the mattress and the big-kid side is a quilted organic cotton and plant-based PLA surface with a 1.5-inch microcoil comfort layer for targeted support. Naturepedic positions the flip as the moment your child moves from the training years into a comfier big-kid bed.

Both sides sit on the same support core: a 5-inch premium innerspring unit made in-house without glues or adhesives, plus organic cotton batting and a polyester spring insulator for cushioning and breathability. The whole mattress is encased in organic cotton. The practical result is that you are not choosing between a waterproof mattress and a comfortable one; you get both, in one product, by turning it over.

What materials are inside this kids mattress?

Naturepedic lists the materials in full, and the list is short on purpose. The mattress uses GOTS-certified organic cotton fabric and fill, food-grade PE waterproofing derived from non-GMO sugarcane, plant-based PLA fiber batting, polypropylene interlinings, polyester thread and coil insulator, steel fasteners, and a steel coil innerspring. Plant-based PLA, derived from non-GMO sugarcane, adds lightweight resiliency and helps wick away moisture.

What is left out matters as much. The mattress is made without polyurethane foam, glues or adhesives, flame retardants, vinyl or PVC, and fiberglass. It is also made without latex or wool, which Naturepedic frames as an allergy-friendly sleep space. For parents screening a child’s room for specific materials, that combination is the clearest argument for this model over a conventional kids mattress.

How firm is it, and will it sleep cool?

Naturepedic describes the comfort level as extra firm, and states that both sides are firm enough to support proper growth and development. The brand’s guidance is explicit: kids need a mattress that promotes healthy alignment as they grow, not one that lets them sink too deeply into the surface. If your child prefers a soft, plush hug, this is not that mattress, and no firmness label will change the design.

On temperature, Naturepedic points to breathable organic cotton and moisture-wicking wool rather than gels, foams, or what the brand calls questionable cooling additives. The brand’s stated approach is that breathable organic cotton helps regulate comfort without those additives. Parents shopping for a child who sleeps hot should read that as passive breathability from natural fibers, not as a cooling technology with a measured performance figure.

What do the trial, shipping, and warranty cover?

Naturepedic lists a 100-night trial on this mattress, described as love it or return it with no questions asked. Shipping is free in 10 to 14 business days within the continental U.S., and Naturepedic lists free shipping and returns. The warranty is a 25-year limited warranty. Those three terms are the ones to compare when you are choosing between organic kids mattresses, because trial length and warranty length are where brands differ most.

Read the linked return and warranty terms for exclusions before you order, and confirm the size selected in the cart. Promotional pricing can change, so treat the live selector as the final checkout price.

Who should NOT buy the Naturepedic 2-in-1?

Skip this mattress if your child is heading into the teen years and wants an adult feel. The extra-firm design and the kids sizing are built for toddlers and young children, and a full at 53 x 75 inches will feel small to a growing teenager. Skip it if you are shopping mainly on price, because a kids mattress at $799 for twin is a premium position in this category, and cheaper conventional options exist. Skip it if your child needs deep contouring or a plush surface, since the brand’s own description is firm comfort for growing bodies.

Skip it if you need latex or wool in the construction, because this model is deliberately made without either. And skip it if you want in-room setup and a longer tryout window, since Naturepedic lists free shipping rather than white-glove delivery here, and the trial runs 100 nights rather than a full year.

How does it compare with the Saatva Classic?

The Saatva Classic is the adult alternative once a child outgrows a kids mattress, and the two products solve different problems. The Naturepedic 2-in-1 is a flippable organic kids mattress with a waterproof side and a firm feel; the Saatva Classic is a coil-on-coil innerspring sold in three comfort levels and two heights, with in-home delivery. The comparison below shows where the two diverge on the terms parents and shoppers actually compare.

Who should buy the Naturepedic 2-in-1: parents of toddlers and young children who want a certified organic, waterproof, firm kids mattress in twin or full, and who value materials made without polyurethane foam, flame retardants, fiberglass, latex, or wool. The listed twin price is $799, the trial runs 100 nights, and the warranty is 25 years. This is the pick when the child’s age and the potty-training stage drive the decision.

Who should buy the Saatva Classic: shoppers buying for an older child, a teen, or an adult who wants a traditional innerspring with three preset firmness choices, two height options, and a 365-night home trial with free in-room setup and a lifetime warranty. It is also the better fit when delivery into the room and removal of an old mattress matter more than an organic kids certification.

What does the World Sleep Almanac score say?

World Sleep Almanac score: 8.0/10 for the Naturepedic 2-in-1 Organic Kids Mattress. The score is an editorial rating based on five criteria: price at equal size, trial and returns, warranty, materials and construction, and public customer reviews. The score reflects how the product is positioned on those criteria as published by the brand, and it is not a lab measurement.

• Materials and construction: certified organic cotton, plant-based PLA, a steel innerspring made without glues, and a flippable design with waterproofing on one side. The absence of polyurethane foam, flame retardants, fiberglass, latex, and wool is a clear strength for allergy-conscious families.
• Price at equal size: $799 for twin and $999 for full places it in the premium tier for kids mattresses, which pulls the score down slightly against cheaper conventional alternatives.
• Trial and returns: a 100-night trial with free shipping and returns listed is solid but shorter than the 365-night trials some adult brands offer.
• Warranty: 25 years is a long term for a kids mattress that will likely be outgrown before the term ends.
• Public customer reviews: this page does not carry a review count or rating for this specific model, so that criterion is scored conservatively.

FAQ

Is the waterproof side safe for a child to sleep on every night?

The waterproofing on the little-kid side is food-grade PE derived from non-GMO sugarcane, and Naturepedic positions it as the easy-cleanup surface for potty-training years and everyday messes. It is one side of a two-sided mattress, so you can flip to the quilted organic cotton and plant-based PLA side whenever you want a softer, more breathable surface. Both sides sit over the same firm innerspring core.

Can this mattress go on a bunk bed or trundle frame?

Naturepedic lists twin, twin trundle, and twin trundle short sizes, with the trundle versions at 6 inches thick and the standard twin and full at 7 inches. The trundle sizes are built for trundle frames, and the listed weight limits are 200 lbs for trundle sizes, 325 lbs for twin, and 450 lbs for full. Check your frame’s height clearance and slat spacing before ordering.

Does the mattress need to be flipped regularly?

The two-sided design is meant to be flipped at a life stage rather than on a schedule: you start on the waterproof little-kid side and move to the quilted big-kid side when the training years are over. Naturepedic does not publish a rotation interval for this model, so follow the care guidance that ships with the mattress.

What happens if my child outgrows it before the warranty ends?

The 25-year limited warranty covers the mattress for its full term, but a child will usually outgrow a twin or full long before that. That is the practical reality of a kids mattress: the warranty is there for defects in materials and workmanship, not as a promise the size will still fit. If you expect to hand it down to a younger sibling, the flippable design and waterproof side are what keep it usable across children.

Is this mattress vegan?

The 2-in-1 Organic Kids Mattress is made without latex or wool, which covers the two animal-derived materials most often flagged in organic mattresses. Naturepedic does not label this specific model as vegan on the product page. If a vegan certification matters for your purchase, the brand’s vegan line is the place to look, and our EOS Classic Organic Vegan review covers that option.
