Review on Adjustable Growing Footrest Casters for Homeschool Furniture in Kids' Furniture: Enhancing Comfort and Ergonomics by Dana Schmidt

I'm glad they don't use a gas bottle to adjust the height here. I've been paranoid since I heard the news about the office chair explosions. The only issue we have is that the reels seem to be weight sensitive. When the child sits on the chair, the wheels are locked. Although this makes the chair stable, it is also difficult to move closer to the table.
