We discovered quickly that the original 2-stage is a misleading marketing gimmick.
Our experience:
Our baby was ready to transition to the crib and we were stoked for this mattress due to positive reviews, but now we're wondering how truthful they were. Baby is a pretty good sleeper anywhere (we lucked out) but couldn't sleep for long stretches on the Newtown. He sleeps on his side or belly now at 8 months, starting on his back at bedtime. We observed that he couldn't roll on this…

Overview
Description
This mattress features a patented Wovenaire core that’s made of 90% free air (yes, air) and 10% food-grade polymer—so basically your baby could breathe right through it.
It’s all wrapped up in a breathable and plush dual-layer quilted cloud cover that provides comfort and unzips for easy washing.
They use absolutely no polyurethane foam, adhesives, metal springs or glue so it’s non-toxic, hypoallergenic, and GREENGUARD Gold certified. A third-party CPSC accredited laboratory showed that a baby gets 97% more air while breathing through a Newton Crib Mattress than on a conventional waterproof crib mattress.
The washable material prevents bacteria growth—and can even pop right in the shower (or rinse off with a hose) for a good washing.
The 2-stage design allows for longevity through the toddler years.

misleading description: not a 2-stage mattress
This is not a 2-stage mattress. I haven't used this product yet and maybe I'll love it once I do, but I was disappointed to discover that it's not actually a 2-stage mattress. Both sides have the same level of firmness. I asked Newton about this and they said: "It is designed to be firm enough for infants while also being comfortable for toddlers. Both sides of the Original Mattress are identical. " This is a different definition of "2-stage" than what I have seen with any other seller of crib mattresses and I think it's very misleading marketing.

Light and breathable
Love this mattress - I even got 2 to have at the grandparents house! Wouldn’t have chosen any other mattress other than the Newton. It gives me a peace of mind knowing it’s light and breathable considering my 3 month old is sleeping on his side and has rolled onto his tummy multiple times.

Peace of mind worth every red cent
Excellent mattress. I have purchased one for every grandchild born in my family. Customer service is excellent. Product quality can’t be matched by any other company.
