Review on Seville Classics Adjustable Sitting Ergonomic Furniture by Sara Lutz

This is exactly what I need. I leave my laptop on it and tilt it just right for use. I had to add something (I used some black screws) to keep the laptop from sliding off. It rolls back and forth easily when I use it on my chair and easy to move around when it's time to vacuum. One of my favorite purchases this year! I'm attaching a picture so you can see where I added the screws, they don't interfere at all.
