Not too firm...not to soft...just right! I was sleeping on a 10 year old futon-style mattress that frequently gave me lower back pain. First night on my T&N and the pain went away. I love it so much and look forward coming home and sleeping on it every night!
The feel of the bed's surface is amazing. With the right sheets, this bed is super comfortable. I would like to compare it to the mint in the future but for now, I will continue to sleep comfortably.
