You're lucky, I have a bear of a time sleeping and often feel physically uncomfortable sleeping on the floor. I bought a cotton-filled Japanese futon mattress and slept on it for 6 months. In the end, I was still waking up with hurt joints, almost like bruising, and I bought a $1,000 mattress instead. So I think it's due to individual nerve differences or something...
