This is confusing to the consumers, and there is really no industry-wide guide to go by. When you look at a mattress purchase, you should also consider the very important cost per night analysis. Using this analogy, it is easy to establish a relative value. A. Space is a critical component of a good night's sleep. In mattresses, bigger is better.
King size is better than queen size.
Queen size is better than full size. Go as big as you possibly can. This is particularly true for Americans who are large. Big people demand big mattresses. You will not regret this even if it means new bedroom furniture.
