This baby mattress contains a breathable natural latex foam core. It also contains organic coir or coconut fibers resulting in super breathability and great support.
Another great internal component is the non-allergenic lamb's wool. Which is great for repelling dust mites and acts as insulation in the winter and cools in the summer.
The mattress itself is enclosed in a organic cotton cover that may be unzipped and washed.
This baby mattress is not cheap. It is one of the more expensive organic crib mattresses. Expect to pay around $500+. It just seems natural latex (comes with a price tag).
Now is it worth the investment? If you can afford it, I think it's a great choice.
