Improve Reading Habits: This book stand is made of high-quality white ABS plastic and high-quality aluminum alloy, making it lightweight and easy to carry for both children and adults. Small adjustments to your reading habits can help reduce shoulder, neck, and back strain while supporting better posture and visual comfort for an improved reading experience. Ergonomic Design: The reading book stand features a 180-degree swivel function and an adjustable height range from 0 to 7.87 inches. You can customize the angle and height based on your seating position and table height to achieve a comfortable viewing angle. The transparent side clips allow clear visibility of page content and enable one-handed page turning. Universal Application and Multipurpose: This book holder stand measures 8 inches in height, with a sturdy front shelf of 6.5 x 11 inches, expandable up to 16.5 inches. It accommodates books ranging from B6 to A4 size. The stand is suitable for books sized 5 to 8.5 inches and functions as a holder for devices from 6 to 13 inches, including iPads and tablets. It can also be used as a cookbook stand, recipe book holder, or book display rack. Easy to Install: The stand is ready to use right out of the box. Assembly is simple—use the Allen key stored beneath the white tabletop to attach the tabletop to the support arm. Note: There are two adjustment nuts on the support arm. Use the wrench located at the bottom of the book holder to adjust the arm tension. For heavier hardcover books or laptops, tighten the nuts securely for stability. This book stand is not recommended for books with very small pages.
