The Matias iRizer Portable Ergonomic Laptop Stand is a notebook/laptop computer support designed for use by individuals with carpal tunnel syndrome or other upper extremity disabilities. The unit helps prevent neck and wrist pain by raising the laptop keyboard and screen to a more comfortable angle for typing. It also allows air to circulate freely under the laptop, so it runs cooler and quieter. The stand fits virtually any laptop. It adjusts to four heights and can be set at an angle of 20, 30, 40, or 50 degrees. The unit has two slim acrylic plates that stack together for storage in a notebook bag. The unit comes with a MiniRizer, a credit-card sized version that can be used as a stand for an iPod, iPhone, cellphone, or business cards. It also comes with carrying sleeves and an instruction card. DIMENSIONS: When folded flat the unit is 11.42 x 8.92 x 0.55 inches. The stand height adjusts from 2.25 to 6.5 inches. WEIGHT: 1.5 pounds.
