30(M) Side sleeper. I tried this pillow on a whim and bought with a package (bedroom suit, Purple mattress, adjustable base, pillows) at a furniture store. My wife bought a different model and I let the salesman talk me into this pillow. This is quite literally the best purchase I've ever made. I had a Purple Harmony pillow before this and the Storm 2.0 Cuddle Curve pillow blows this out of the water. I will post another review in 1 year to review the longevity and lomg-term reliability of the product.
