BoYata Laptop Stand 360° Rotating PC/Tablet Stand, Lectern Stand, Angle/Height Adjustable, Ergonomic Design, Heat Dissipation, Non-Slip, Posture Improvement, Back Pain/Kyphosis Relief, Compatible with Laptops and Tablets up to 17 inches, Presentation, Telework, Work from Home (Black) Reference price: 4299 yen [360-degree rotation & 180° angle adjustment at 2 points] The BoYata N33 laptop stand allows you to freely rotate the top plate 360 degrees without tools, depending on your usage situation. It has 2 points of 180° adjustment, and the height and angle can also be adjusted in multiple stages. ★ Simply rotating it allows you to easily share the screen with the person opposite you, making it the perfect laptop stand for watching movies with family, meetings and presentations in the office, and working from home. [Stepless height adjustment & posture improvement] The BoYata laptop stand is designed based on ergonomics, allowing stepless height adjustment (4CM-30CM). By adjusting the height and posture to suit yourself when working on a PC, the burden is reduced and kyphosis is effectively prevented. ★ Note: When typing directly on the keyboard with the stand raised high, it may shake slightly, so we recommend preparing a separate keyboard. [Convenient storage & excellent heat dissipation] Effectively utilize the space under the laptop stand to store keyboards, USB hubs, memos, pens, etc. when not in use, and keep your desk tidy. ★ Ventilation holes are provided on the contact surface with the laptop, reducing the worry of heat buildup even when working for long hours in the summer. [High-quality design & wide compatibility] The stylish silver color and smooth edge processing and matte body create a sense of luxury, making it a PC stand that can be easily matched with interior decor wherever it is placed. ★ Compatible models: MacBook Air, Macbook Pro, Microsoft Surface, Google Pixelbook, Dell, HP, Acer, ASUS, Lenovo, Alienware, and other 11-17.3 inch laptops.
