When sitting in an office chair the first area of the chair to focus on is the part you sit on all day, the seat. With your back against the backrest, the seat should support most of the length of your thighs without applying pressure to the back of your knees. Waterfall seats (which most chairs now come with) are ideal for allowing you to sit comfortably and properly. Your seat height should be set so that your thighs are approximately parallel to the ground when your heels are firmly planted on the ground. If it is not possible to have your feet flat on the ground because your work station is too high and not adjustable, a footrest is a good addition to keep your feet flat and body in proper posture. Movement throughout the day is encouraged, so do not feel as if you always need your feet to be planted on the ground. There is generally a lever on the right side if not the left that when pulled up allows you to move either up if your taller or down if you are of shorter stature. A tip for adjustment is to start with your seat at its highest and lower it gradually until it is at a comfortable height. as you cannot usually raise your seat while you are sitting in it.
After you fully understand how to adjust your chair, place the chair in front of the work area in which you will be using it most often. If your chair can be adjusted pneumatically simply apply a little pressure and push down on the seat while pulling the lever up to have the chair go down in height. To have the chair go up, apply a little pressure to the bottom of the seat and pull up with one hand while simultaneously pulling the lever up with the other. Computer chairs that do not have a pneumatic lift can be adjusted by loosening the height adjustment bolt by hand and pulling up or pushing down on the seat until the desired height is reached. Once you are happy with the height of the chair you will then need to tighten the bolt back to its original place.
Once you have determined where you will be spending most of your time sitting and ergonomic accessories that may also play a part in the height adjustment of your chair, you will want to locate where the button or lever is on your chair that controls the height. On most chair models, it is generally located on the right hand side of the chair right below the seat. Some higher end chairs may even have pictures on their levers explaining what each lever on the chair does. All chair models will vary, and you will need to take the time to understand what each button does in order to fully adjust your chair to meet your needs.
Next you will want to determine the area the mat is going to be used. You want to have a mat that will cover enough of the floor for you to be able to at the very least roll back to get out of your chair. It is best to use a tape measurer and measure from the desk outward to see how far the mat should extend before your purchase. Most chair mats are sold in multiple sizes to accommodate most desk areas and are large enough for regular uses. Measurements can be found in product spec and information area, so it is good to have your desk areas measurements prepared beforehand. If you typically like to roll your chair from one desk to another or between two areas it is best to get the largest mat possible.
If you look at antique French wing chairs, or newer chairs echoing the Louis XIV or Louis XV period, you may well see a lower seat in the bergère style. Similarly, in 18th century England Hepplewhite tried lowering the seat in his designs. He called the wings saddle-cheeks, perhaps knowing that they were called cheeks, not wings, in France. Ears is their other name, used in some parts of Europe, and remembered in the old-fashioned British name lug-chair. (Lugs is slang for ears.) American wing chairs, also called easy chairs, were often considered bedroom furniture suitable for anyone frail or tired, sitting quietly in their room. Both antique and modern wing chairs may be associated with elderly people; a high seat and back with built-in draught-proofing offer an appropriate kind of comfort, and remind us that another name for this piece of furniture is grandfather chair.
Another feature that is crucial for a good chair to have is adjustable armrests. Most chairs that have adjustable armrests can easily be lowered or raised by pushing a button in and manually pulling the armrests up or pushing them down. Armrests have to be at the right height for your body, if they are too high it will force you to position your arms awkwardly. If armrests are too long you might find yourself to be slouching or sitting in an awkward position which might start to cause a back ache. While typing, your arms should be able to swing freely. Armrests should be positioned about half an inch below your elbows, with your elbows hanging comfortably at your side. If your arms are resting on the armrest while you are typing, you will be inhibiting the normal arm movement which will cause extra strain on your fingers and their supporting structures.
