I have grown dissatisfied with my mattress. I bought a new one 2 months ago, and I chose the firmest grade of foam available in my country. I don't like springs. When choosing a mattress, my goal is to find something that provides sufficient support without being too rigid. The foam grade vendors suggest for my weight is extremely soft, like sleeping on cotton candy. I don't know why people have this obsession with softness -- it is uncomfortable and terrible for your back.

My new mattress is perfectly fine but it is still not firm enough. Foam quickly loses its rigidity, and I can feel that it is happening already. It is not as firm as it was when it arrived. On a whim, I decided to sleep on the floor. Not literally on the floor, as I have no wish to press directly against the ground all night. I piled the folded plastic plaques we previously used for my son's playpen and wrapped them in a pair of thick quilts. The result was still very rigid but gentler on my joints. I slept on it yesterday. It was a success. I felt refreshed, only woke up once and got back to sleep right away. It was better than sleeping on my mattress.

I looked up traditional Japanese tatamis and futons, but they must be imported in my country because they were more expensive than a mattress. I ordered 4 meters of EVA -- each roll is 2 meters by 1 meter, 1 centimeter thick. I intend to stack them for a thickness of 2 centimeters, providing greater comfort with the same amount of rigidity. I may transition to (kinda) sleeping on the ground full time.

How do you like your mattress? Do you sleep on the floor as well? Or in something that resembles sleeping on the floor?

I just changed rooms, and my new neighbor makes noise. It's not much of a problem for other people, but I wake up at the slightest sound or the slightest change in lighting. Because of this, I am not able to sleep properly. I have tried earbuds and earplugs, but they hurt my ears. Can you suggest how I can become a heavy sleeper? Or how to sleep in this environment?

and a good japanese futon mattress as well.

i'm moving from a house into an apartment and am scaling my life down significantly. this seems a pretty good option... but unfortunately i don't know a whole lot about either of these (yet) so i'm looking for some guidance.

thanks!
