国家市场监督管理总局批准发布了《家用儿童学习桌、椅》国家标准（GB/T 48090—2026），该标准适用于3至14岁儿童使用的家用学习桌椅，涵盖阅读、书写、绘画等日常使用场景1。标准建立了多重安全风险防线，重点防范挤压夹伤风险、有毒物质释放以及电气安全等问题1。
在电动升降功能的安全防护方面，标准规定了严格的要求1。当桌椅电动升降装置受到外力阻碍时，必须在5秒内将挤压力下降至安全阈值1。松开操作按键后，桌面位移不得超过10毫米，以防止意外移动1。此外，标准禁止使用声控和远程控制实现升降调节1。对于可倾斜桌面，标准要求其须通过5000次开合循环测试1，确保长期使用的安全性和耐久性。
The State Administration for Market Regulation has approved and issued the national standard for household children's study desks and chairs, GB/T 48090—2026, applicable to study furniture used by children aged 3 to 14 for reading, writing, and drawing.1 The standard establishes comprehensive safety safeguards for motorized lifting functions, product performance requirements, and multiple protective measures designed to mitigate risks including crushing and pinching injuries, toxic substance release, and electrical hazards.1
The new standard imposes strict requirements on the safety of electrically adjustable desks and chairs.1 When external force obstructs the lifting mechanism, the compressive force must decrease to a safe threshold within 5 seconds.1 Additionally, once an operating button is released, the desktop displacement must not exceed 10 millimeters.1 The standard explicitly prohibits the use of voice control or remote control systems for height adjustment.1 For tilting desktop surfaces, manufacturers must demonstrate durability through 5,000 opening and closing cycles.1
