Review context: Ben purchased and opened a Pottery Barn Kids Lullaby Organic crib mattress for a review published in 2017. His photos and observations describe that sample, not necessarily the current Lullaby model.
Our verdict
Ben was disappointed that the original Lullaby sample contained more synthetic material than he expected from its “organic” description. He found a pocketed-coil unit, a water-resistant barrier and foam among the layers. If organic content is a priority, read the component labels and certification scope carefully; a product name alone does not establish that every layer is organic.
What we liked: the original sample had a two-sided design and coil support. What gave us pause: its organic wording did not match Ben’s expectation of an all-organic mattress.
Ben’s original teardown
Ben bought the mattress directly from Pottery Barn Kids and opened it to inspect the layers. The 2017 product description advertised a firm infant side and a different toddler side; he did not notice a substantial difference in feel between them. That subjective comparison is not a safety or firmness certification.
Inside, he observed individually wrapped coils connected to a steel perimeter, a barrier and foam. He also saw a cardboard-like component and material he thought might contain wool. He did not conduct laboratory testing to identify the composition or certify the percentages.

What does “organic” mean here?
The historical description referred to blended cotton and wool, a water-resistant barrier and soy-enhanced foam. A foam containing a plant-derived ingredient is not automatically organic; likewise, a certified component does not make the entire mattress certified organic. Check the exact label and whether a certificate covers the finished product or an individual material.
Pottery Barn Kids currently includes a Lullaby crib mattress in its crib mattress guide. The present product may differ from the original sample, so confirm the manufacturer’s current specifications rather than assuming the teardown applies unchanged.
Infant sleep safety comes first
Use a firm, flat mattress that fits the crib snugly and is intended for that crib. Place babies on their backs and use a fitted sheet, keeping pillows, blankets, bumpers and other soft items out of the sleep space. The American Academy of Pediatrics explains its safe-sleep recommendations.
For a two-sided mattress, follow the manufacturer’s labeling for the infant and toddler sides and consult your pediatrician if you have questions. Do not open or use a damaged mattress for a child; Ben’s teardown was for review, not a recommended setup step.
What to compare before buying
| Question | What to check |
|---|---|

| Two-sided design | Clear infant/toddler labeling and instructions. |
| Care | Water resistance, cleaning instructions and replacement policy. |
Price and current availability
The original review recorded a price of $379; that is not a current price. Compare the current model number, dimensions, materials, warranty, delivery and return terms. The original review is valuable for understanding the older mattress but cannot certify today’s product.

Frequently asked questions
Did Ben inspect the mattress?
Yes. He purchased and opened the original sample, photographed its layers and recorded an unboxing video.
Was every layer organic?
The original sample contained synthetic components. The product name alone did not establish that every layer was organic.
Can I use a soft topper in a crib?
No. Follow infant safe-sleep guidance: a firm, flat, properly fitting mattress with a fitted sheet and no soft bedding.
Is the current model identical?
We have not established that. Check the current product specifications and labels.
