Hard as a rock for side sleeping
To me, this is a hard mattress. I am a side sleeper and this is noticeably hard and uncomfortable for me.The mattress seems well made, but who knows The materials and mattress have no certifications that I can find. I purchased an Avocado Green topper to see if it would help, and even that wonderful product cannot blunt the hardness of this bed. If you want the firmest possible mattress, its comfort level would be fine for you.
