Very comfy! I wouldn’t say it’s super soft though. It’s firm enough where you don’t feel the other person moving around very much but soft enough where it forms around your body perfectly. I have slept on it for 3 nights now and have woken up so rested and ready for the day. I did slept on it after 5 hours of it being unboxed(idk if that was good to do or not but it seems fine). Also being someone that has neck and back pain daily, this mattress is excellent for forming to your body and relieving pressure. I also never sleep through the night and wake up feeling exhausted usually so the last 3 sleeps have been amazing!
