Review on Dapolu Adjustable Aluminum Laptop Stand - Portable, 7-Level Height and Angle, Ergonomic Computer Holder - Foldable Silver Notebook Stand for Laptops 10-15.6 Inches by Troy Early

It's perfect for any size computer so there's no limit to the model, it's easy to set up, just open it, adjust the height you want and clip it to keep it still! It's comfortable, with a rounded shape at the bottom to hold and an extra pad, it won't hurt your wrist at all when using it. Of course it doesn't help the computer to get warm :)
