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.

Great Pillow!
Size: King (Pack of 1)
Excellent product. I have been searching for a pillow that wasn't too soft or too hard and supported my neck. I now wake up without a stiff neck and a headache. Wonderful!
