Most people have heard of adjustable beds. Everyone has seen numerous print advertisements and late-night infomercials telling of their virtues. Few, however, know the origin of them.
Electric adjustable beds were actually the work of the eccentric millionaire, Howard Hughes. An avid aviator, Hughes was involved in a near-fatal crash in 1946 shortly after take-off for a test flight. For the remainder of his life-thirty years–he had chronic pain. Today, he would likely be diagnosed with Reflex Sympathetic Dystrophy (RSD). When hospitalized in 1953, he concocted the idea of an adjustable bed that could diminish suffering by allowing a person to elevate their back and legs, finding the position most comfortable for sleeping.
The idea he came up with has given relief to countless sufferers of many illnesses ranging from heart disorders to hernias. The ability to elevate the back allows gravity to aid the heart in circulation, takes pressure off your hips, and lets you sleep more deeply than a flat bed does.
An adjustable bed, especially when used with a memory foam mattress, can give you the perfect night’s sleep you have been dreaming of all your life. There are beds with programmable memory controllers so you can find and then permanently set the best position for sleeping, reading, or watching cable. A touch of the control arranges the position automatically. There are even adjustable beds that provide a stress-relieving massage. Choose from ten speeds; the bed will return to its last position after thirty minutes of relaxing massage time.
For anyone who has difficulty falling asleep, who tosses and turns restlessly, who wakes up still fatigued, sore, and reluctant-or unable–to move, an adjustable bed can provide a world of relief. A memory foam mattress, the ability to raise and lower your back and legs, and a deep massage at bedtime–what better way to assure a good night’s sleep!

To describe an ergonomic laptop stand would be quite a chore because in fact the word may refer to a variety of things, their only similarity being that they were all designed and engineered to cater to those who want more ease and convenience in using their laptops. There are a lot of items like these to be found in magazines, retail stores or even the internet. Simply put, ergonomic laptop stands can be classified as anything from the simplest table to the most complex accessory that gives you that extra comfort when using your laptop.
In spite of similar appearance, there are marked differences between the table and desk ergonomic laptop stands. A table on one hand has only its surface available for your laptop to rest upon, while the desk stand has several other features like compartments and extra levels and surfaces where you can put other things for ease. The ergonomic desk-style laptop stand really lives up to its name because when you have one, storage is never ever a problem. You can access everything you need from these stands, with minor effort on your part. Some of the compartments are even tailor made for other computer accessories such as printers keyboards, CPUs and various paper products that could come in handy.
Table-type laptops, though not being similarly loaded like a Swiss army knife with features, is still very ergonomic in its own uniquely simple way. Laptop stands such as these usually have pull-out surfaces for your mouse or keyboard . To add to that, many also come with adjustable heights to suit any user or situation while the wheels that several models have with them make them mobile and ready for action. This is really the type of laptop stands for those who want simplicity combined with function.
Lastly, the accessory-type ergonomic laptop stands are composed of the different platforms that can be affixed to other furniture or surfaces to accommodate a laptop. An example of this is a pull-out drawer specifically designed as an attachable accessory for a table.
Some of these drawers even have locks to secure the laptop. Others look like wall-mounted stands of televisions that have a movable neck and a platform to carry the laptop on its end.

What would you say is the second most frequent of doctor visits in this country? Some might guess heartburn; others might say a nagging cough. The answer, however, is lower back pain. The problem among adults 45 to 65 years of age is so widespread that over 75% can expect to be affected by it. If you are one of the 65 million patients in the United States who suffers from back pain, it is a relief to realize that only about one in ten patients actually need surgical intervention.
Lower back pain manifests itself in several different ways. Some patients have persistent aching in their backs, others feel terrible pain shooting down their legs, still others become so stiff they can hardly straighten up. Weakness and numbness in certain areas can also be experienced. Part of the reason there are so many different kinds of pain is that there are over fifty different nerves that can be affected.
In 90% of the instances, the source of back pain is the motor and sensory nerves that weave through the spinal cord and back. These critical nerves are surrounded by the bones of the spine and slip out through holes to other places in the body. When these nerves are pinched for any reason, pain follows. The back muscles seize in response to the nerve irritation, and pain and stiffness result. Sometimes a bulging disc is at fault. Other times, the cause of the problem is a herniated or ruptured disc. Whatever the source, back pain can be incapacitating.
You can effectively try to treat back pain on your own at home. Take an anti-inflammatory, such as ibuprofen, to relieve swelling. Taking it easy for two or three days is recommended. Find a position that does not cause pain and rest. The idea is to halt the pinching of that nerve. If symptoms do not subside or if they worsen, seeing a doctor is advised. Tests can determine the source of the pain and rule out more dangerous issues. Physical therapy may be advised. Fortunately, in most cases, the pain can be stopped without surgery.

Do you have a favorite chair at home-maybe not something that attractive to look at, but so comfortable you cannot wait to flop down and get comfortable? Maybe it is a great lounger or a cozy arm chair. You slave all day thinking about the moment when you can fall into that chair and relax. Just think! How great would it be if you could look forward to sitting in your office chair that much!
Maybe you can. When a desk chair is ergonomically designed to adjust to your body height you get a great fit and can sit comfortably for longer periods. Too many people are sitting in chairs that are too large for them or with contoured back support that hits all the wrong places. Others scrunch up in chairs too small for them. There is no way you can work well when you are not comfortably seated.
With an executive office chair, you get handsome looks and unparalleled support for every body part. Bent wooden arms give it a distinctive look, but the most important feature of these arms is that they are adjustable. Everyone working at a desk needs to be sure their lower arms rest at the proper angle to minimize strain on wrists and shoulders. The seat and back angle, as well as height may be fitted, too.
Good lumbar support is a feature of this chair as well. How many times have you gotten out of your old desk chair groaning and trying to massage the murderous knot in between your shoulders or in your lower back? Part of it is probably caused by user error: sitting too long without a change in position, but your chair is also often a culprit.
Learning to sit with good posture will help you avoid strain on joints, muscles, and circulatory system. When you know where you need support, at what angle your wrists should be, how high your knees should be in relation to the seat, and other important elements of posture, you can get the ultimate benefit from an adjustable chair. Obtaining an ergonomic chair, maintaining good posture, and taking frequent breaks to stand and walk around a little will have you feeling much better when you leave work.
