Furniture that meets users' specific needs is essential for promoting their well-being. It should be free from harmful substances and designed with safety in mind to prevent poisoning or injury. The production process follows strict dimensional standards, ensuring quality and usability. When furniture is designed based on ergonomic principles, it should exhibit the following characteristics:
1) The materials used are natural and non-toxic, ensuring a safe environment for users.
2) Green products designed with ergonomics in mind prioritize human comfort. They consider both static and dynamic body conditions, avoiding any negative impact during regular or accidental use.
3) The design aims to extend the product’s lifespan, making it more durable and reducing energy consumption during reprocessing.
4) The furniture should have high quality, incorporating cultural and technological value.
These furniture items must support user health. For tables and chairs, there are established height standards. Table heights range from 700 to 760 mm, with four specifications, while chair seat heights are between 400 and 440 mm, with three options. The height difference between the table and chair should be between 280 and 320 mm.
The correct height allows users to maintain two key vertical postures: first, when sitting, the thighs and calves should form a near-right angle, with no pressure on the underside of the thighs. Second, when arms hang naturally, the upper and lower arms should be perpendicular, and the table top should align with the underside of the forearm. This ensures proper posture and reduces strain. If the height is incorrect, it can lead to poor posture and long-term health issues. Therefore, the space under a desk should be at least 580 mm in height and 520 mm in width.
For sofas, the front seat width should not be less than 580 mm, the seat depth between 480 and 600 mm, and the seat height between 360 and 420 mm. Regarding wardrobes, the distance from the top of the hanger to the cabinet top should be 40–60 mm, and the space from the bottom of the hanger to the cabinet floor should be at least 1350 mm. The depth of the closet is typically 600 mm, considering shoulder width, and should not be less than 500 mm to allow proper door closure.
Bookcases also have size standards; each shelf should be at least 220 mm high, as smaller shelves cannot hold standard-sized books. The spacing between shelves is generally 300–350 mm.
When choosing safe furniture, consumers should consider the following:
1) Stability: Look for furniture with a wide base to prevent tipping.
2) Strength: Avoid thin or flimsy structures that could break easily.
3) Hazard traps: Check for sharp edges or gaps that could cause injury, such as bed ladders that might trap children.
4) Construction: Ensure all joints are tight and free of cracks or exposed screws.
5) Assembly: All parts should fit properly, with secure fastenings and functional locks.
By paying attention to these factors, consumers can make safer and healthier choices when selecting furniture.
