Personally, I always prefer to sleep on a pillow. Because good sleep is very important to me. And to take care of my health during sleep, I use only orthopedic sleep products. After reading this article https://fierytrippers.com/hotel-stays-and-sleep-quality-orthopedic-pillow/ , I even prefer to take an orthopedic pillow with me to the hotel. And it really helps me. Because I used to often face the problem of poor sleep while staying in a hotel.
