Choosing the correct office chair – a short guide

Have you ever thought about how many hours you spend in the office sitting in your office chair? Have you ever wondered how important this item of office furniture is for your health and your well-being? Have you ever thought that the nagging neck pain or sciatica pain can depend on an office chair which is not right for you? If the answer to these questions is "yes", with this short guide we will try to provide you with some advice on how to choose your chair for the office and what features need more attention.

 

Wheels

The wheels are usually rubberized or non rubberized. The first allows easier movement on hard office floors (marble, wood, ceramics), the second on office carpets and rugs. The wheels should also feature a breaking mechanism.

Armrests

Armrests provide comfort, but you have to pay attention to the type of desk that you are using. Often the armrests' height exceeds your desk's height. In this case it's better to buy a chair without armrests or buy an office chair that gives the possibility to adjust the height.

Height adjustment mechanisms

These mechanisms are one of the most important aspects to consider before buying an office chair. The minimum should be: swivel seat, adjustable height with gas lift, adjustable back height and depth. Office chairs can also be equipped with options like the addition of an adjustable lumbar support. Obviously these addons can make the office chair more expensive!

Seat covering materials

In this case it is a choice of aesthetics and not comfort. The most common and cheapest are polyester chairs, available in numerous colours, and artificial leather office chairs. Manager's office chairs are instead usually available in leather, wool fabric and polyester mesh and are generally more expensive.

Some interesting facts about coffee and tea

The country in the world where they drink the most coffee is Finland, with a consumption of 12 kg per year. The country where they drink the least is Puerto Rico, with 400 grams of coffee per person.

The country in the world where they drink the most tea is Turkey, with a consumption of 3.13 kg per person. The one where they drink the least is Mexico, with 15 gramms.

Coffee spread to Europe in the 17th century as the "wine of Arabia". The first people to bring this product were Venetian merchants, close to Istanbul, which at that time was the capital of the Ottoman Empire.

Tea also spread to Europe in the 17th century. People say that tea was imported to the old continent by Dutch and Portuguese merchants, which contributed to the spread of a beverage that the Chinese had known about for 5.000 years.

The great German composer Johann Sebastian Bach loved coffee so much he dedicated a song to it: the Kaffeekantate, performed in Leipzig between 1732 and 1735.

Tea bags date back to 1904 and were invented by mistake: Thomas Sullivan, a tea merchant, used silk bags to send samples to his customers. These customers mistakenly thought that the bags were intended to replace the traditional metal infusers.

The most expensive coffee in the world is produced in Thailand and is called Black Ivory Coffee. To produce it some elephants are fed with coffee beans; after the beans are ejected naturally, they are washed and minced. Through this "process" people say that the coffee gets a sweet chocolate-like aroma and a kilogram can cost 1600 Euros.

The most expensive tea in the world is produced in China and doesn't have a name yet, but will costs $ 150,000 per kilo. The name of its inventor is An Yanshi and he is a professor at the University of Sichuan. Why is it so special? The plants are fertilized exclusively with panda dung.

After oil, steel, grain, coffee occupies the fourth place in importance in the scale of international trade.

Because of the high cost of transport, towards the end of the 17th century in England the cheapest tea came to cost seven shillings per pound, which corresponded to the weekly pay of a worker.

The origin of Post-it notes

Many of us use post-its every day, but who invented them and why did he do it?

Art Fry was a researcher at 3M and simultaneously sang at North Presbyterian Church of North St. Paul, Minnesota. In carrying out this activity he came across constantly a simple but annoying problem. During the celebration of Sunday Mass he used a hymn book, and within it he inserted leaflets used as a bookmark. However, these sheets used to fall each time the book was opened, becoming useless and frustrating the poor Fry.

However, as a researcher, he remembered the invention of a colleague at 3M, Spencer Silver, who had designed a sticker which was abandoned because its durability and resistance was too low. The idea was both simple and ingenious: it was necessary to make bookmarks sticky, but not too much, so that it was possible to remove them without tearing out the pages of books, making them unusable.

Easier said than done. Fry began to develop his own idea and after a year he began to distribute the first package to their colleagues so that would be used as bookmarks. It was a big surprise when he realized that the post-it notes were not used only as bookmarks, but chiefly to mark notes to attack on unfinished practicals.

So it was that Art offered his invention to the sales office, but was greeted with suspicion. However, thanks to his insistence, in 1977 the first test from 3M was made and in 1980 they began production and distribution of Post-its.

Now the Post-it is one of those inventions that has changed peoples lifestyles and that is the reason why Fry and Silver both entered in the list of the best Americans inventors.

Post-its now come in all shapes and sizes and are a favourite office product item.

Curious facts about glue

The oldest use of glue can be traced back to 80.000 years ago. At that time Neanderthals melted birch wood on stoves using with a special technique, which obtained a sticky substance similar to tar they used to build hunting tools.

The most powerful glue in nature is produced by a bacterium, the Caulobacter crescentus, which produces it to attach to rocks and walls.

The most powerful glue produced in the laboratory has been synthesized by researchers at MIT in Boston who were inspired to a protein secreted by mussels.

In medicine a material has been developed similar to the gels, inspired by the sticky secretions of snails and insects, that may function as a surgical glue stable, elastic and insoluble in water. This compound would allow applications which were impossible until now such as applying patches directly on to a patient's heart. Further trials are currently under way (source: Science Translational Medicine)

The Guinness Book of World Records has awarded the prize for the "heaviest vehicle lifted with glue" to Loctite. It took 9 drops of common Super Glue Universal 3G to paste the ceiling of a pick-up truck to a city car to give a total weight of 5.02 tons.
