I am totally in agreement with all that is stated in this excellent article. I am a manufacturer and retailer of custom-built ergonomic chairs in Cape Town, South Africa. I use an assessment form for each and every client, and the chair is made to exactly suit the client. I have three models of chairs each of which have specific weight carrying characteristics, i.e. up to 120kgs, 120 - 150kgs and 150 -300kgs. I also manufacture a range of assistive devices, like lumbar cushions and coccyx wedges. These assistive devices can also be custom built to suit the individual client. The 120kg chair has 6 different shaped backs, so one will suit the client. If none of these work, we foam the chair with the client sitting in the chair.

Algunas ideas para tener en cuenta: - Sillas con respaldo completo - Apoya brazos - Que la altura se pueda regular - Que el usuario sienta comodidad - Se puede incorporar un desnivel para apoyar los pies - No estar muchas horas sentado - Realizar estiramientos con frecuencia Para tener un buen rendimiento es indispensable contar con los equipos adecuados, y aunque no todos lo tengan presente, la silla es una herramienta más de trabajo.

Als erstes ist wichtig wo der Stuhl im Einsatz ist. Z.B. Büro oder Fertigung. Dann sollte der Stuhl auf den Anwender bzw. die Tätigkeit zugeschnitten sein. Auch nicht zu vernachlässigen ist, welches Polster verwendet wird und mit oder ohne Armlehnen.

Una vez en el trabajo, es evidente cómo una silla ergonómica puede ayudar vastante, puesto que estas sillas están diseñadas para apoyar la postura natural del cuerpo, reduciendo la tensión en la espalda, cuello y hombros. Además, promueven una mejor circulación sanguínea y ayudan a evitar la fatiga, lo que se traduce en una mayor productividad y bienestar general.

Here’s an often overlooked feature: armrest contour. Some office chairs — often the inexpensive ones — have concave armrests. It’s as if you’re meant to fit your forearms exactly into them. I advise against using a chair with armrests like these. Because if instead you naturally sit with your forearms resting across the armrests, they will chafe your forearms. This sounds like a small detail, but it gets very distracting. I recommend looking for chairs with flatter armrests.

Un aspecto clave que no mucha gente tiene en cuenta es la elección de una silla con descansabrazos o sin descansabrazos. A priori parecería que es una silla con descansabrazos es una buena opción de confort. Sin embargo los inconvenientes se presentan cuando ajustas correctamente la altura de la silla y los descansabrazos chocan con la superficie de trabajo. Inmediatamente se bloquean los movimientos y giros naturales con el cuerpo. Si vas a elegir una silla con descansabrazos asegúrate que no sean fijos porque van en contra de una adecuada ergonomía. En mi experiencia prefiero emplear una silla sin descansabrazos y si más bien una superficie con una profundidad aproximada de 60 cm que me va a permitir apoyar los brazos sobre la superficie.

Consider: Material and Fabric: Leather or vinyl might be easier to clean but can cause discomfort in warmer environments. Weight Capacity and Stability, Ease of Adjustment, Seat Depth and Edge, Neck Support: This can reduce strain on the neck and shoulders, Environmental Sustainability, Testing the Chair, Adjustment Training, Warranty and Customer Support, Ergonomic Accessories,

I always suggest to my corporates clients about considering these before choosing an ergonomic chair: Material Matters: Opt for a breathable, cushioned seat wide enough for hips and thighs. Adjustable Backrest: Backrest should support the spine's natural curve, adjustable in height, angle, and tilt. Lumbar Support: Adjustable depth and height for optimal lower back support. Versatile Armrests: Adjustable in height, width, and angle to support elbows and forearms. Head and Neck Comfort: Look for an adjustable headrest for personalized height and angle. Swivel Base: Ensure a swivel base for easy rotation without body twisting. Floor-Friendly Casters: Choose casters suitable for your floor type for smooth and safe movement.

Como bien plantean los que me precedieron, no existe una técnica para la elección de las sillas. Sin embargo, es fundamental que éstas tengan ciertas características que nos permitan amoldarla a nuestros gustos (y medidas). Si bien es indispensable que la misma no tenga vencido ninguno de sus componentes, es fundamental que el usuario realice estiramientos con frecuencia, como así también adaptar su espacio de trabajo para tener una mejor performance.

In my experience here are few points to be considered: Armrest Alignment: Ensure armrests are at elbow height, supporting relaxed shoulders. Dynamic Movement: Encourage occasional shifts and movements to prevent stiffness. Monitor Height: Set your computer monitor at eye level to reduce neck strain. Footrest Use: Consider a footrest for additional support and comfort. Regular Breaks: Incorporate short breaks to stretch and maintain overall well-being. Task-Specific Adjustments: Modify settings based on the nature of your work for optimal support. Proper chair adjustment is key to preventing discomfort and promoting a healthy work environment.

De acuerdo con mi experiencia, sugiero que el usuario puede estar cómodo, erguido, con los brazos en los apoya brazos, con el mentón y la vista dirigida hacia la pantalla (evitar curvaturas, malas posturas, etc). Si no tenemos el hábito de usar los apoya brazos, que éstos se apoyen en la mesa, es decir, que estén a la misma altura.

It's important to remember that once you have set it to suit your body for everyday tasks, you are not locked into that position for life. The chair may need readjusting over time dependant on the work you're doing, or what you feel is ergonomic and comfortable that day.

En lo personal, luego de sentir los dolores que todos seguron atraviesan tras estar largos tiempos fue: 1. Asegúrarme de que mis pies descansen cómodamente en el suelo. 2. Y que el soporte lumbar encaje en la curva de tu espalda baja, de tal manera que los reposabrazos permitan que los hombros permanezcan relajados.

Many of my patents are struggling with this: Regular Breaks: Take short breaks every 20-30 mins to stretch, stand, or do light exercises, preventing prolonged sitting fatigue. Eye Level Monitor: Ensure the monitor is at eye level to reduce strain, avoiding tilting up, down, or sideways. Use Support Accessories: Consider a footrest, lumbar pillow, or seat cushion for extra comfort and support. Dynamic Sitting: Change positions frequently, promoting flexibility and reducing the risk of stiffness. Mindful Arm Position: Maintain wrists straight while using the keyboard or mouse, avoiding strain. Adopting these habits maximizes the benefits of your ergonomic chair, promoting a healthy and comfortable work environment.

What allowances do you make for those clients with Type A or B diabetes? Do you create a gap under the hamstrings, to allow better blood flow to the feet, by using a footpad?

En mi experiencia, el uso adecuado de una silla ergonómica implica más que solo sentarse correctamente. Es importante levantarse y moverse regularmente para evitar la rigidez. Además, ajusta periódicamente tu postura y la configuración de la silla para adaptarte a diferentes tareas.

n my experience, maintaining your ergonomic chair involves more than meets the eye: Stability Check: Ensure no wobbling; address instability promptly. Tension Adjustment: Fine-tune tilt tension for optimal comfort during tasks. Cushion Evaluation: Regularly check seat and back cushions; replace or add support as needed. Healthy Sitting: Foster even weight distribution; avoid excessive leaning. Cushion Rotation: Rotate cushions periodically to maintain consistent support. Proactive care ensures your ergonomic chair lasts and supports your well-being.

We once watched a short time lapse study of persons seated on a long distance rail trip over several hours, the passengers looked like they "had ants in their pants". Its important that body movement for muscle comfort are part of the ergonomic design. Designs should allow users to wriggle and adjust for blood flow and refreshing muscle joint positions

Sin ser para nada experto en mantenimiento de sillas, podrí hacer las siguientes recomendaciones: - Revisa y ajusta los mecanismos de la silla periódicamente. - Limpia la silla según las instrucciones del fabricante, prestando especial atención a las áreas de contacto frecuente.

In my opinion, maintaining your ergonomic chair is crucial for comfort and health. Regularly check and tighten screws, bolts, and levers to keep the chair stable. Clean it using a damp cloth and mild detergent, avoiding harsh chemicals that could damage the material. Regularly vacuum the upholstery to remove dust and debris, and treat any stains with a gentle soap solution. Keep moving parts like casters and swivel bases lubricated with silicone spray. Replace worn or damaged parts like cushions or casters to ensure the chair remains supportive and comfortable. Proper upkeep not only prolongs your chair’s life but also enhances your sitting experience.

Optimal chair setups go beyond the chair itself. While a quality ergonomic chair is crucial, consider other elements for a holistic experience: Desk Setup: Choose a desk that aligns with your body proportions. Ensure a comfortable height for forearms and maintain a clutter-free workspace. Monitor Arm: The often-overlooked monitor arm is transformative. Regardless of chair quality, a poorly positioned monitor can hinder your efforts. A monitor arm provides flexibility to adjust the screen to eye level, preventing neck strain and promoting a neutral spine position. Conclusion: Ergonomic excellence is holistic. Pair a top-notch chair with the right desk, peripherals, and monitor arm for a workspace prioritizing health and elevating work.

In my experience, when considering ergonomic chairs and their impact on workplace health, it's also important to look at the broader environmental and psychological effects of your workspace design. Incorporating natural light, sufficient ventilation, and quiet spaces can significantly enhance the benefits of an ergonomic setup. Also, consider the dynamic nature of work encourage movement and stretches throughout the day to complement the physical support of an ergonomic chair. These additional factors contribute to overall well-being and productivity, creating a more holistic approach to workplace health.
