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.

Will this mattress fit in the delta children 6-1 crib?
Best Answer: Yes. The Newton Baby Breathable 2-Stage Crib Mattress is a standard-size crib mattress (52" × 28" × 5.5"), and it is designed to fit all standard full-size cribs.

Poor quality control - disappointing quality of product
I purchased a Nest convertible crib. Product arrived damaged, a split/separation in one of the wood pieces (something that should have been caught by quality control).
A separate pieces of wood looks like it was damaged and sanded down in production, then they tried covering the damage up with the finish (the piece of wood should have not been used).
Some pieces arrived with cosmetic damage (scratches, a mark down the whole side of one of the pieces), other pieces are sanded down in areas…

Newton is a bad company
I ordered an overpriced mattress but apparently what I purchased was multiple unsolicited spam emails per day.

Miracle Mattress!
We have a special needs daughter that isn't very mobile. She is always hot and sweats like nothing I have ever seen. Every morning and after naps, her head and hair is soaked. The sheets are soaked. We can't even keep blankets on her. She wakes up all during the night sounding her alarms and waking everyone.
Thought this was a little "pricey" for a crib mattress; but, we had to try something else. Received the mattress and swapped it out. The first use was during her daily nap. She woke…
