Same. Also the newton breathability claims are a lot of fear mongering. I do think it’s nice that you can take apart the mattress and wash it, but the waterproof exterior of the naturepedic does basically the same thing. The mattress cover on the naturepedic is breathable and you can see lots of testing on their site. Super safe.
I got the naturepedic because it’s listed as cleaner than the newton when tested https://www.consumerreports.org/babies-kids/crib-mattresses/best-crib-mattresses-a9683309833/
Same on both.
Naturepedic
Since you mentioned eczema, you may want to go with a Naturpedic. We got one for our baby's crib because we learned about how harmful the VOCs from most mattresses are. Its made from organic cotton with no polyurethane foam. They have larger kids and adult mattresses. I recommend going with a firm mattress to be as safe as possible. Some of the reviews on Amazon mention the kids mattress isn't comfy, but idk if the adults mattresses are too soft. I don't have a large mattress, I'm also researching a safer mattress for cosleeping.
We had the naturpedic for a crib mattress. I know they are supposed to be very firm but it was so hard and I wonder if that’s why he didn’t sleep well in his crib. We got a full size Avocado a couple months ago for a floor bed so we can Co sleep and it’s very nice! I will say it felt too soft for the first couple days and we were worried. But it firmed up as it aired out. Now it’s very comfortable. He has been sleeping very wonderfully on it, too.
We used Naturpedic for crib and Avocado for his toddler floor bed.
I am getting Naturepedic but I prioritize things like natural fibers, no PFAs, etc. Naturepedic and Avocado are the main options in the “crunchy” category. Otherwise I think Ikea has some cheap cribs & mattresses.
