Many serious health problems have been associated with lack of proper sleep. The mattress you sleep on will determine to a great extend how much your body rests. You need to get enough sleep when you lie down and it is not just about how much time you spend on the bed.
When it comes to getting the desired amount of sleep, it is only by having the right mattress that everything makes sense. You will find people investing heavily in mattresses for this reason. It is better to buy an expensive mattress that will give you peace at night, and durable enough to save you on cash.
When you find that your guests are not comfortable in the Airbnb your rent to them, nothing much you can do to recover the situation. You may have an immaculate listing altogether, but that is not what will make them stay happy.
