The floor offers optimal support to the mattress, and even many individuals prefer the feel to place their mattress directly on the floor. When you place a bed directly on the level, it helps cold air circulate all over the base of the mattress, thus allowing people to stay fresh the entire night. Most of the sleepers find it easy to get on and off the mattress when placed directly on the floor and thus consumes lesser effort. Placing mattresses on the floor can diminish strain on the body over time. Also, if you set the mattress directly on the floor, you'll be able to cut off the extra expenses on purchasing a bed. But there are some side effects.The mattresses have a direct exposure to dust mites and dust particles when positioned on the floor. The mattress can even absorb heat, moisture, and restrict airflow when place on deck. Such problems happen in humid and hot weather. Your mattress even gets access to bed bugs when placed on the floor, which requires thorough cleaning later on to remove these insects.
