    • Great kids mattress
Size: Twin
I bought this for my toddler who was outgrowing the toddler bed. It’s comfortable to sleep in and he sleeps through the night. I wanted to get a mattress that was green guard gold certified. I like that I was able to purchase on Amazon straight from Naturepedic seller. The mattress arrived vacuum sealed in a box. The directions were straight forward to unbox and unroll. After the mattress was out of the vaccum seal it was ready to go. I could hear the springs as it undid and felt that it was sturdy with no lumps or imperfections. I am super satisfied with my purchase! ... show more

    • Peace of mind, but not comfortable
Size: Twin
My 3 year old loves her new big girl bed but I find it extremely uncomfortable. It feels stiff and crunchy and like you can feel the springs. I bought my other daughter an Avocado mattress years ago and it’s so much more comfy. At least I know the Naturepedic one is clean even if it’s not comfy.

    • 1000% Recommended for kids with allergies/asthma
Size: Trundle
My preschooler was having chronic allergies/asthma attacks every night until I realized his toxic mattress was the culprit. I wish I bought an organic mattress years ago! The first night he laid his head down on this mattress, he didn't cough a single time. I wasn't paid to write this review ya'll. If you're a parent of a toddler/bed wetter the waterproof side makes PM potty training less daunting. BUY THE MATTRESS. Also want to mention, I've fallen asleep next to him on the new mattress & I've never slept deeper. Although it's firm, it's much better for my neck & back issues -- I've since purchased a 2nd mattress from Naturepedic. I'm thrilled & Ill tell everyone about this wonderful, AMERICAN company, THANK YOU!!! ... show more

    • No chemical smells
Size: Trundle
Materials are quality and it fits nicely in a twin bunk. Best of all it had no off gassing or smell at all. It's not as soft as I would like but my kids have not complained.

Size: Full
2nd mattress we purchased and it came nicely, and good quality- these hold up well as our first is still lasting well and had it for years. 2nd kid needed a mattress so this is our second and good for the price and organic components. Worked well. Will likely order another for another kid in the future. Thanks. ... show more

    • Perfect mattress for transition from crib to "big kid" bed
Size: Twin
We love Naturepedic products. They are a responsible domestic company with high quality. We bought their crib mattresses for our twins. Now that they are ready for twin beds, we wanted to go with Naturepedic again and they did not disappoint. We appreciate having the waterproof side since our kids still have accidents. But we also know that this mattress could last them for a long, long time. The packaging was also great. It was easy to take out of box and was in great shape. ... show more

    • Really bad smell had to return
Size: Twin
Had to return the mattress The smell and or offgassing from the mattress was way too strong couldn’t imagine my child using it. Can’t imagine this is OK. Can’t tell you about firmness, quality, comfort, expansion rate or thickness because the smell was so bad.
