Made of high quality aluminum alloy, the LPS04-5U Foldable 6-Level Adjustable Laptop Riser features sleek surface and elegant appearance. Capable of firmly holding most 11”-17” laptops and tablets. At only 0.12” thick, the riser easily folds flat for storage or transport. Six levels of height adjustment provide optimal viewing and comfortable working angle. The open design offers maximum air-flow for heat dissipation so devices maintain cool operation. Soft silicone pads keep the device in place during use and protect surfaces from scratches.
