In the modern technology era, where much of our work is done on computers for extended hours, swivel and ergonomic chairs are now common in office furniture.
Choosing the right size for an office chair is crucial for ensuring comfort and improving work productivity. Let's explore the standard dimensions of office chairs and how to determine the right size for your needs in the following article!
1. Standard Dimensions of Office Chairs
To select the appropriate office chair, pay attention to three key dimensions: height, width, and depth of the chair.
1.1. Office Chair Height
Office chair height typically ranges from 90 to 130 cm, depending on the user’s needs and purposes. This height is measured from the base of the chair to the top of the backrest (or headrest if present). Additionally, consider these specific height measurements:
Seat Height: Usually between 45 and 60 cm, measured from the ground to the seat cushion. This can be adjusted with height-adjustable chairs.
Backrest Height: Typically ranges from 40 to 50 cm, measured from the seat cushion to the highest point of the backrest. This height generally reaches the user's shoulders if there is no headrest.
Armrest Height: Ranges from 20 to 30 cm, providing a comfortable arm position. Measured from the seat cushion to the highest point of the armrest.
High-end ergonomic chairs often feature adjustable heights to accommodate desk levels and user preferences, allowing the overall height to adjust by 10 to 20 cm using a lever or smart button.
1.2. Office Chair Width
Chair width refers to the overall width from the left armrest to the right armrest. The standard width, accounting for the sitting area plus an additional 3 to 5 cm for comfort, generally ranges from 50 to 70 cm. Additional measurements include:
Seat Width: Typically between 45 and 55 cm, measured from the outer edge of the seat cushion.
Base Width: Typically ranges from 60 to 70 cm, measured from the outer edge of one base leg to the outer edge of the opposite base leg.
1.3. Office Chair Depth
Chair depth is measured from the backrest to the front edge of the seat cushion. This is crucial for providing comfort and support for the back and thighs. Office chair depth usually ranges from 40 to 55 cm. Before purchasing, it’s recommended to visit a showroom to ensure the depth matches your leg length and sitting posture.
Additionally, some ergonomic chairs offer depth adjustments of 5 to 10 cm via a lever system integrated under the armrests.
2. Benefits of Choosing a Swivel Chair with Dimensions Suitable for Your Body
Selecting a swivel chair that fits your body size offers numerous benefits, especially for office workers' health. The right dimensions provide a comfortable sitting experience and significantly enhance work efficiency.
2.1. Improved Sitting Posture Beneficial to Health
A well-sized swivel chair maintains proper sitting posture, with adjustable and reasonable seat height and depth. This smart design helps you sit with your back straight and feet perpendicular to the floor, supporting the spine and reducing pressure on other body parts like the lower back and thighs.
2.2. Reduced Risk of Posture-Related Health Issues
Sitting in an improper posture for extended periods increases the risk of spinal and joint issues, such as scoliosis and back pain. A properly sized office chair promotes a comfortable and correct posture, positively impacting both physical and mental health.
Additionally, the adjustable seat depth and back height support the lower back, helping maintain proper posture and reduce stress on the spine. By maintaining correct posture, the chair also alleviates pressure on spinal discs, thus reducing the risk of herniated discs and related problems like cervical spondylosis and spinal spurs.
The seat width and armrest height are adjustable to distribute body weight evenly, reducing strain and fatigue on large muscle groups like the back, thighs, and shoulders. By decreasing pressure on each body part, the chair helps prevent excessive muscle strain and discomfort.
2.3. Enhanced Work Performance
Comfortable seating prevents distractions caused by back or neck pain. Without pain-related concerns, you can complete tasks more quickly and effectively.
An appropriately sized swivel chair creates a comfortable workspace with optimal working posture, reducing work-related stress and improving mental health.
2.4. Extending Chair Lifespan and Reducing Repair Costs
When frequently changing posture due to an ill-fitting chair, uneven pressure distribution can lead to quicker wear and tear, reducing the chair's lifespan and increasing the need for repairs. A chair used correctly will maintain its function and appearance for a longer period, saving maintenance costs for businesses and ensuring maximum safety and comfort for users.
3. How to Determine the Right Size for an Office Swivel Chair
Determining the right size for an office swivel chair is crucial to ensure comfort and work efficiency. You can base your selection on the following factors to choose a chair that fits your needs:
3.1. Based on User Characteristics
Choosing a chair size based on user characteristics is necessary to ensure comfort and optimal support for the body. Each person has different height, weight, and usage needs, so selecting the right chair helps avoid health issues caused by improper sitting posture.
Consider the following characteristics to choose a chair that fits personal dimensions:
Weight: Users should select a chair with a sturdy frame, thick padding, and load capacity suitable for their weight. High-end ergonomic and office chairs that meet BIFMA standards typically support weights up to 130 kg. Additionally, prioritize chairs with adjustable tilt tension to avoid difficulties and the risk of tipping when reclining.
Usage Habits and Job Nature: For those who sit for extended periods, choose a chair with high-quality, breathable padding that supports body parts well, ideally with a comfortable backrest and lumbar support. Adjustable armrests are important to accommodate various working positions and reduce strain on shoulders and arms. For jobs requiring frequent movement, select a lightweight chair with flexible wheels and easy adjustments.
3.2. Based on Floor Size
Selecting chair size based on floor size is important to ensure a well-organized and comfortable workspace. Overcrowding a small space with too many chairs can make it feel cramped and difficult to move around. Ensure that the chair fits the floor area to optimize workspace while maintaining comfort and efficiency.
To determine the appropriate chair size for the floor area, follow these steps:
Step 1 - Measure Floor Area: Use a tape measure to determine the length and width of the chair placement area. Calculate the total area based on these dimensions.
Step 2 - Choose an Appropriately Sized Chair: Subtract the space occupied by shared furniture (tables, cabinets, shelves, etc.) from the total floor area. Divide the remaining space by the number of chairs to find the average area for each chair. Then, select a chair with width and depth that fits the average floor area. Ensure that the chair does not occupy excessive space, leaving enough room for movement and arranging other items. For smaller spaces, prioritize chairs with a compact design and ease of movement.
3.3. Based on Desk Height
A chair that does not match the desk height can lead to posture issues, causing strain on the neck, shoulders, and back. When the chair and desk are at compatible heights, you can maintain a comfortable and effective sitting posture, reducing the risk of health problems. Therefore, choosing the chair size according to desk height is essential for ensuring comfort and proper posture.
To determine desk height and choose the appropriate chair, follow these steps:
Step 1 - Measure Desk Height: Use a tape measure to measure from the floor to the top of the desk. Record this height as a reference for selecting the chair.
Step 2 - Choose a Suitable Chair: Select a chair with adjustable height so that when seated, your arms form a 90-degree angle with the desk. Ensure the seat cushion is between 40 and 50 cm from the floor, allowing your feet to rest comfortably and perpendicularly. Check that the chair provides adequate lower back support and that the backrest is high enough to support your spine while working.
3.4. Based on Intended Use
Choosing chair dimensions based on intended use is essential to ensure the swivel chair meets job requirements and provides maximum comfort. Depending on the specific job, users may need a chair with special features and dimensions. For example, office chairs typically require flexibility and strong back support, while chairs for brief meetings may be simpler and less adjustable.
Here are some guidelines based on intended use:
Office Employees: Choose a chair with adjustable height, backrest, and seat depth to provide the best support for the back and neck. Ensure the chair has adjustable armrests to reduce strain on the shoulders and arms.
Executives: Larger chairs are suitable for executives, featuring thick cushions and high backrests for comfort and authority. These chairs often come with premium materials and flexible adjustment features.
Meeting Rooms: To impress clients, meeting rooms should feature luxurious designs with high-end chairs and smart adjustment features to provide the best experience. If office space is limited, choose stackable or foldable chairs to optimize space. Additionally, consider designing flexible meeting rooms to accommodate various purposes.
4. Common Mistakes When Choosing Office Swivel Chairs
Beyond size, other factors should be considered to select the ideal office swivel chair, creating a comfortable and efficient working environment. Here are 5 common mistakes in choosing office swivel chairs:
Overlooking Backrest Recline: Chairs without backrest recline adjustments can cause discomfort and back strain. Without proper support, you may experience spinal issues and uncomfortable sitting posture, leading to stress and fatigue during work.
Ignoring Material Quality: Chairs made from non-breathable materials can cause heat and discomfort. Opt for chairs with breathable materials like fabric, mesh, or leather, preferably environmentally friendly, to maintain a comfortable temperature throughout the workday.
Not Considering Color Before Purchase: The chair’s color is also important for creating a harmonious and aesthetically pleasing workspace. An appropriate color enhances work spirit and provides comfort. An unsuitable or glaring color can reduce focus.
Choosing a Chair with Insufficient Features: A chair with minimal functions or basic features that do not meet your needs can be uncomfortable and inadequate for body support. For example, a chair lacking height adjustment, armrests, or lumbar support is unsuitable for long periods of sitting and may cause fatigue and back pain.
Selecting a Chair for the Wrong Purpose: Choosing a chair not suited for its intended use can affect comfort and work efficiency. For instance, a multi-purpose chair meant for meetings or training might not provide the necessary support and features for a dedicated work chair, leading to discomfort and reduced work effectiveness.
