The Invacare® Rolls 900 Series is designed to meet the special needs of the most demanding user. A reinforced 900 chair is the industry standard when it comes to durability and reliability, because we have strengthened the 900 in numerous ways. With supports. Gussets. Reinforcements. The entire chair is custom-made to withstand just about anything. In fact, the 900 redefines the term “custom wheelchair.” Each one is built to the exact specifications of the user. The chair is available in over 150 widths and depths, almost 20 different backs, numerous seat-to-floor heights, with a weight limitation up to 450 lb., resulting in a chair that can accommodate almost any user.
