<h1 class= "pgc-h-arrow-right" > say goodbye to the bad habits of doing, how to choose a chair? </h1>
In recent times, I believe that many small partners have been "trapped" by the epidemic at home for a long time, basically sitting in front of the computer every day for more than half of the day, so it is necessary to have a good office chair, otherwise sitting in front of the computer for a long time can not stand up. I have bought some so-called ergonomic chairs before, and it is found that it will be better than ordinary office chairs, but there is still a great distance from the real ergonomic chair, and later it is found that the sponge of the armrest and the seat part is already dry and cannot bounce back, and the sponge's dryness makes the cushion become hard, very uncomfortable! Recently, I decided to be a little nicer to myself and got the Okamura Okamura Contessa2 ergonomic chair, which I spend at least 10 hours a day.
Okamura's craftsmanship is not necessary to say, it is really "quality determines the value of its own products". The price of office chairs on the market ranges from 100 yuan to 1,000 yuan and 10,000 yuan, because of the previous bad experience, so this time I chose to consider mainly from the ergonomics and comfort. Now in May, my side has ushered in a hot summer of more than 30 degrees, so the chair does not consider the leather version, but chooses a comfortable and breathable mesh style, so that you don't have to worry about sitting up like the leather model and feeling hot.
<h1 class="pgc-h-arrow-right" > Classic, Unboxed Details of Contessa</h1>
▲ The packaging box is really very very large, the weight is about 30KG, just received when the courier brother directly placed on the first floor, and then wanted to carry the whole box to the 2nd floor, found that it is really too difficult, can only be unpacked and moved upstairs to assemble. The inside of the package is filled with buffer corrugated paper to protect transportation, and the interior is mainly divided into 3 major pieces: backrest + cushion, five-prong chair foot, air pressure rod and so on.
▲ All the accessories, the main accessories have been assembled, such as the cushion and the backrest is integrated, and the chair foot part of the roller skating pre-installed, so only need to install the five-claw chair foot, air bar, etc., if you choose the headrest, you also need to simply get a few screws to get it, and the girl is very simple to install.
▲The one-piece molded aluminum alloy base adopts the common five-claw design, and after installation, it is also felt that the grip is very firm and it is not easy to follow the shaking. The five-pronged chair foot is made of metal bright design, the whole foot looks really atmospheric, and the inside of the chair foot can be seen using stiffeners, which can improve the sturdiness and durability of the chair.
▲ The chair wheel is a universal two-wheel design, the wheel adopts PU wrapping edge, rolling on the wooden floor will not hurt the floor, and it is very quiet. I used to buy a regular office chair, and the wheels were of the ordinary kind, making a harsh rolling sound when moving, and hurting the wooden floor. Therefore, when choosing an office chair, in addition to the ergonomic design and comfort mentioned earlier, it is also necessary to consider the base part of the chair wheel, if the quality is not good, the fastest damage may be the chair wheel.
▲ Although Okamura is known for "quality determines the value of its own products", it is still necessary to carefully check each chair wheel, after all, it cost so much money to start. Check each wheel once to see if there is any rolling that is not smooth.
▲ The air pressure rod is: Okamura Okamura customized South Korea Sanhong SHS 2.5mm thick pipe wall Air pressure rod, the outer pipe wall diameter of about 50mm, the air pressure rod inside the pure nitrogen filling, the load weight of 150kg, through 120,000 times of rotation performance durability test and SGS safety testing certification, in short, the quality is excellent, it can be seen that Contessa2 material is really not sloppy.
Many people think that the office chair is still so exquisite, can you sit on the line?! In fact, the quality of the air pressure rod determines the safety. The inside of the qualified bar is filled with an inert gas: nitrogen, which is extremely stable, so that the service life and safety of the product can be guaranteed. However, because of the high cost of nitrogen, some small domestic brands with a mixture of fish and dragons use compressed air instead of nitrogen to fill the gas rod, and the thickness of the pipe wall of the air pressure rod is also very thin, which is a great safety hazard.
How do you tell if the bar is filled with air or nitrogen? In fact, it is very simple, inert gas in addition to not burning, but also has a good lubricating effect. The air pressure rod filled with nitrogen is very smooth, uniform, and does not stutter during the ascent and descent process. The compression space is poorly lubricated due to the gas mixture, and the air-filled air pressure rod will have obvious fast and slow discrepancies and stuttering sensations during the process of rising and falling.
▲ Install the air pressure rod, it is very simple, do not need a tool to insert it into the center of the base hole, you need to pay attention not to insert the air pressure rod backwards.
▲Contessa2 has two kinds of headrest options, one is a small headrest, and the other is a large headrest with mesh cloth. This chair I chose is a mesh large headrest, when sitting for a long time can tilt the chair, head rest headrest small rest, large headrest compared to small headrest can have a larger support range, even if the side rest is also very comfortable.
▲The cushion and backrest of the Contessa2 can be said to be the soul of the design of the whole chair, and it is also the most expensive core component. The more eye-catching is the one-piece metal seat frame, most domestic chairs will not make a one-piece metal seat frame, but use direct injection molding plastic instead. After sitting up, you can feel that this chair is really very different, such as the pressure of partition hardness, the pressure of the front of the cushion and the contact part of the thigh is very small, the pressure of the middle of the cushion and the contact part of the buttocks is moderate, and the pressure of the cushion and the tail part of the hip is the largest, so the partition hardness pressure is very ergonomically designed, simply say that the place where the force is changed is forced, and the force is just right.
▲ After the completion of the installation of the headrest and the chair, continue to look at some of its details, there are many places that can be adjusted, in addition to the conventional headrest, waist pillow and other parts, there are some details.
< h1 class="pgc-h-arrow-right" > W's chair, what details are special? </h1>
▲Contessa2 supports wire control, and the cable part of the wire control is relatively soft, so there is no jerky feeling to control, and it is very smooth. Chair armrest part: 4D armrest design, can achieve high and low, front and back left and right adjustment, the armrest surface is a soft rubber layer design, the previous chair has been a hard plastic design, without any sense of rebound, sitting for a long time to lean on it feels very uncomfortable, the design of the soft rubber layer is better than the sponge durability, not only high resilience, there will be no dry phenomenon, the soft rubber layer also has a benefit is easy to clean, dirty with a damp cloth to wipe it clean.
▲Pull the lever under the handrail to adjust the lifting and lowering adjustment height of the handrail, and adjust the range of 100mm up and down.
The left and right adjustment of the armrest can be adjusted to the left or right at multiple angles, and the angle of 22.5° can be adjusted.
The front and rear adjustment of the armrest can adjust the position of the armrest forward or backward, the front and rear 40mm adjustable range, 5 gears of adjustment
4D armrests can allow users to diversify to meet the various states of arm comfort support, this detail of the adjustment of the place is indeed practical, in my experience everyone uses the computer desk may not be the same, in the case of the computer desk fixed, can only be used to the chair to adapt to the computer desk, so the chair can be diversified adjustment is necessary.
▲The cushion is a thickened elastic sponge material with high breathability, and the soft mesh mesh used against the back also has the characteristics of breathability and comfort, and it is very comfortable to sit up. Cushion partition hardness support to ensure long-term use, can have a good support for the human body, of course, no matter how to design the excellent ergonomic chair, but also to assist in correcting the sitting posture, slow down the pressure on the human body for a long time, or it is recommended that the small partners in front of the desk for a long time to refuse to sit for a long time, from time to time stand up and exercise.
▲ The mesh backrest is very comfortable, compared to the leather backrest to breathe a lot of comfort, summer do not have to worry about the back is not breathable to cover the sweat. Now many office chairs are also designed with mesh cloth, although the same as mesh cloth, but also have to consider the place: elasticity and durability, if the mesh workmanship will bring obvious sitting gap, and the service life is limited, it is easy to deform. The Contessa2 gives me the impression that it is elastic and not soft or hard, and that it is comfortable to sit on, with a supporting curve on the back. Although the headrest is fixed, it has a fine-tuned design and can be adjusted according to the lean of different users' heads.
▲When you press the cushion repeatedly with the palm of your hand, you can see that the sponge elasticity of the cushion is very good, and the rebound is very fast. Before I sat on some back net sitting net chair, this kind of full mesh design just started to sit when I did not feel that there was any big problem, time will find that the mesh has a loose situation, although many brands claim that the mesh can sit for a long time will not be loose, but the real experience is still there, but the loose is not too exaggerated, the cushion part of the support is obviously not as good as new. I carefully compared the previous chairs and looked at the patented 3D isohardness sponge cushion of the Contesa2 before I dared to bleed into it.
After sitting through Contessa2, I found that it was really different: the cushion part is designed with a 3D curve, using MDC technology, seamless gradient one-time molding cushion, and many domestic cushions are very different, because its entire cushion is divided into 3 stages of hardness: the front part is more comfortable, because this part is used to support the thighs, and the soft part can reduce the leg pressure of the thighs; the middle part is moderately soft and hard, because after the hips sit up, the entire body stress point of the human body is concentrated here. If it is too soft or too hard, it is very uncomfortable to sit for a long time; the back end part is hard, which can bring better force balance effect and improve the overall sitting comfort. Simply put, the cloth cushion of Contessa2 is soft and hard, just right, not too hard or too soft and uncomfortable, and there is a big difference between the ordinary cloth cushion.
▲ There are control switches designed on the left and right sides of the cushion, which need to be pressed at the same time to adjust the displacement of the cushion front and back, and there is a control lever under the right side, which is to adjust the backward resistance, and there is a gear adjustment above, rather than the traditional rotation damping adjustment. The adjustment of the front and back amplitude of the seat cushion, the adjustable range of 50mm before and after the front and rear, when adjusting, the seat cushion is unoccupied.
▲Contessa2 has a lever under the front end of the left and right armrests, the right lever is to adjust the pitch angle of the chair, and the left lever is to adjust the height of the chair. The previous chairs were controlled by the lever on the cushion chassis, and when adjusting, they needed to be specially extended to control it, which was very inconvenient, especially for girls or children, and the Paper was more difficult, contessa2 was designed in the armrest part to solve these inconvenient control problems.
▲ Adjust the height of the chair, just pull the lever with your left hand, you can easily adjust, up and down 100mm adjustable range, chair height 420 ~ 520mm. For the adjustment of the chair pitch, it is also necessary to pull the lever with the right hand, adjust the pressure of the backrest, and adjust the pressure of the backrest in combination with the resistance control lever of the backrest. Pitch 26° adjustable range, no fixed gear, combined with the lever adjusted to its own position after locking. In addition, Contessa2 also has a clever design, that is, it will adjust according to the pitch angle, and the cushion will also raise the angle to support fine adjustment of the hardness of the thigh partition.
▲ Some of the details of the workmanship of Contessa2 can be seen that this chair is very fine in all aspects, and the whole chair is very designed. If the chair in the early 10,000 yuan is balanced in terms of workmanship and design, it also confirms that "quality determines the value of its own product" is by no means casually said.
<h1 class="pgc-h-arrow-right" >Contessa2 made me reject "Ge You Lie"</h1>
Is Contessa2 good or bad? I summarize from these points:
From the design, contessa2 design in all aspects is very good, the appearance to the control, is a very high level. Compared with the traditional office chair, it is much more convenient, rather than a decentralized functional layout, but almost the armrest part concentrates the control adjustment of most chairs. The five-pronged legs and the one-piece seat frame are made of aluminum alloy, which is strong and lightweight.
From the material, customized air pressure rods and composite double-layer mesh backrests, elastic sponge cushions, pay attention to safety, but also ensure comfort and durability. The inner pure nitrogen filling bar of the 2.5mm thick pipe wall can be clearly felt in the height adjustment of the chair and the load weight: there is no jerkiness, high stability, and people will not shake left and right when they sit on it.
From the comfort, what impressed me the most was the soft rubber layer of the 4D armrest, and the daily elbow is the body part with the most supporting armrest, with high resilience, and there is no stuffiness in summer use. The support of the mesh backrest, when sitting on the chair backrest will be a good support for the entire body back, the chair in the waist part of the design curve projection, sitting on it can also support the waist of the body, reducing the feeling of sedentary fatigue.
Is it easy to sit? Good to sit. Is it comfortable? Okamura's patented 3D isohardness sponge soft cloth cushion is really comfortable. Contessa2 is a chair belonging to the posture correction type, which can help adjust the correct sitting posture very well, while also supporting the tail vertebrae, back, waist, hips, legs and other parts of the body, reducing the fatigue caused by long-term sitting. Let me refuse to "lie down" in the chair, change bad habits, and sit correctly! Sit in front of the computer for a long time, but also remember to stand up, walk more and exercise, so that you can have a healthy body. I hope that this sharing can be helpful to the small partners who plan to start an office chair in the near future.
