Most people don't consider the benefits of a full size air mattress as an alternative to their current spring mattress, but think nothing of keeping an air mattress guest bed for use by visitors. Do visitors need less comfort than their hosts, or perhaps these guests are getting the better deal and the more comfortable rest! Many prefer an air mattress to one of a traditional sprung interior for a number of reasons outlined below. Most people do not keep themselves informed on advances in air mattress technology, and likely still look upon them as being nothing but a huge bag filled with air using a foot pump. If they think that they would be completely wrong - is that you, or are you more au fait with technology and understand what is needed for a good night's sleep? Adjustable Each Side Of course you are, but maybe you just need a quick reminder of the benefits that a full size air mattress can offer when compared to a regular spring coil mattress. First, a modern air mattress is not just a big bag of air! It is carefully designed with internal compartments that balance the pressure when you lie on them, and the design of modern air mattresses enables the hardness to be adjusted each side so that you and your partner can set your side of the bed to be just as hard or soft as you like it. Sleep is an extremely important part of your life and plays a very important role in enabling you to maintain good health. A mattress is not something to be left to chance, and vary rarely will two people in a partnership have exactly the same preference. Most believe that a full size air mattress cannot match a spring equivalent for comfort and durability. Here are a few facts that might change your mind. Even Pressure Air mattresses are newer technology than spring mattresses that are made from a large number of small coils or springs inside the mattress. When you lie on these coils, the pressure is not evenly spread, and the coils will be compressed according to the direct pressure placed upon them. Your body will tend to sag along with them because the coils either side will not take up any significant part of the load - they cannot due to their design. Sure, there will be a small degree of load spread but not much. An air mattress contains a number of inflatable air chambers and when you lie on one, the sir pressure in the chambers around the direct area you are lying on will take up a large part of the load. Air is like water - the pressure is equalized throughout the interconnected air pockets, so your body is given more even support. Not only that, but the air compartments can be segregated in a manner that enables each half of the bed to be independently adjusted for pressure so that you can each have your half of the mattress set at the ideal pressure for you. Unlike a traditional spring mattress, you don't have to compromise, with perhaps neither of you getting your ideal level of comfort. Longer Lasting The life of a full size air mattress is greater than that of a coil sprung bed, and the reason it will last longer is not only because it is an air mattress guest bed that is rarely used. Springs lose their strength with repeated use and your bed can sag after 2-3 years of continual use. Not so with a good quality air mattress that is self-adjusting according your body size, weight and sleeping habits. You don't have to rotate a full size air mattress to keep it performing well as you do its coil equivalent, because the air chambers do not change shape or wear with repeated and continual use. They last significantly longer and many find them superior to the more tradition type of mattress. Nor do you get the same level of edge sag as you do with a sprung mattress, when the springs at the edges of the bed wear out through the concentrated weight of people sitting on them. Yes, there is lower resistance at the edge of an air mattress, but not too low. What Price Sleep? Doctors often recommend harder air mattresses for those with back conditions because they offer more support with less of a tendency to sag when you are sleeping. You can have orthopedic-style hardness on your side while your partner has their side set a bit softer. Perhaps a full size air mattress is the more expensive, particularly the very high quality designs, but think what you gain in terms of comfort and save in terms of the life of the mattress. In any case, what price do you put on a good night's sleep and your health?
