Sleep is one of the most important functions of the human body since it allows us to relax, recharge, and allows our brain to take the time to carry out different processes like memory processing, healing and regenerating and so on. Now, we tend to sleep on proper beds and mattresses, and this is a practice that has become common all over the world, however, if you go to Japan, while you will still a lot of people using Western Style beds, a great chunk of the population still uses futons to sleep.
Now futons are Japanese mattresses that you can roll onto the floor, sleep in, and then roll them back up in the morning. Interestingly enough, they are slowly becoming popular in the West as well, and a lot of people choose to voluntarily sleep in futons over western style mattresses and bed frames.
The first reason why futons are so popular is that they are really minimalistic. You do not have to do much with a futon. There are no accompanying pieces or frames that have to be attached. All you have to do is roll the futon out when you want to use it, and once you are done using it, you just have to roll it back up and then put it somewhere else.
The best futon is made of 100% cotton and is great for your back. Futons are firm but not hard, and this is why they are great for your back, and this is something backed by research. Plus, you are sleeping on the floor as well, and the floor will help you make sure that your spine is properly aligned as well. This way your back stays in good condition, and you will find yourself sleeping really well with them.
