Great toddler pillow
Size: 2.7"H (Standard)
We decided to get this for a toddler pillow for our son. I'm a little intense about what kinds of materials he is exposed to and I feel comfortable with latex. The pillow cover is synthetic and I'm not sure how I feel about that, but it is removable. It seems really comfortable for him--supportive but soft. He loves sleeping on it. And I don't have to worry about him burying his face in an ultra lofty pillow that would be making me nervous all night. I might buy one for myself and my husband at some point too!

Too thin...
Size: 2.7"H (Standard)
It is way too thin and doesn't even feel like real latex. Disappointed."

Buy if you love flat pillows
Love the fact the pillow can be separated into two sections. The thinner section is perfect for stomach sleeping; add the other piece for side sleeping. Add a down pillow for back sleeping. The pillow is fluffy, unlike the rock slab feeling of memory foam.

Only about 1.75 inches thick, and hard as a rock.
Size: 2.7"H (Standard)
This is nowhere near the 2.7 inches advertised. After waiting 4 days for it to expand, it never got higher than 1.75 inches from bottom to the highest point. Also, I'm not sure what kind of Talalay they claim to use; this was hard as a rock.
