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.
