Idk why I always wake up with either my sides or neck or smth hurting when I wake up but that didn't happen while I stayed at a hotel. It's not like I'm an old broken man who should be waking up expecting this.
I sleep fine on just a couple blankets on the floor, sure maybe i could sleep a bit better on a fancy mattress but this is essentially free and extremely convenient so i would not say that spending a bunch of money on something that takes up space permanently is worth it. I would rather improve my health in other ways.
