Take a load off anywhere you go when you have the Backtab Portable Comfortable Backrest. Designed to go anywhere you go, this device offers total support and comfort. The Backtab is extremely easy to use. Simply unfold and take a seat. The Backtab features a highly durable hinge system. Using glass fiber reinforced plastic and extremely strong stainless steel hinges, the system props up the angled backrest. In fact, this strong material is the same stuff used for helicopter rotor blades. In addition, the back of the Backtab uses CNC-machined “claws” to keep the entire system upright. You can rest the full weight of your upper body with total peace of mind. Additionally, the Backtab is complete with a water-repellent, tear-proof material at the base. It rolls out to cover the ground and give you a clean seat. Measuring only 10.2 inches long, the size of an average tablet, the Backtab can truly go anywhere.
