"How exactly are office chairs defined?
An office chair is specifically designed for use within an office environment, typically featuring adjustable height, an adjustable backrest, and adjustable armrests. Its primary purpose is to offer users a comfortable seating posture while providing excellent support to minimize fatigue and enhance productivity. According to the American National Standards Institute (ANSI), an office chair is described as a chair intended for use in an office or similar workplace, providing comfort and support to its user.

The American Association of Spine Surgeons (AOSS) recommends that office chairs incorporate certain features such as adjustable height. The seat height should allow the user’s feet to rest flat on the ground with their knees bent at a 90-degree angle relative to their hips. The backrest should also be adjustable to support the lower back effectively, and armrests should be height and position adjustable for optimal arm support.
The Ergonomics Society further suggests that office chairs should include a well-cushioned and supportive seat cushion. The backrest should provide both lumbar and neck support, while armrests need to be height and position adjustable to ensure proper arm support.

Hand And Foot Care
The hand is the second face of a woman, from the hand can judge a woman's identity, cultivation and life quality. If you don't care carefully, others will see the signs of time from your hands. And the foot is a microcosm of the human body, and more and more people have been working with facial care.
We only have very few sebaceous glands on the backs of our hands, so it's easy to dry out, and it's a smart woman's idea to keep hand cream handy. Apply it every time you wash your hands to replenish moisture and nutrients. You can use all the high-quality hand protection products that are commonly available on the market. This does not mean that you can use them freely. If the back of the hand is tight and there are small fine lines, it is necessary to choose mild products, such as those containing glycerin, mineral oil, lanolin and other moisturizing ingredients. If you find yourself with itchy, peeling skin, look for products that contain soothing ingredients like mint and chamomile and moisturizing ingredients like minerals and glycerin. The best time to care is also in the evening, before going to bed with almond cream hand cream, then wear a pair of thin plastic gloves, better for the skin to absorb nutrients.
