The Nitrum is the newest ultra-lightweight wheelchair from Quickie. The Nitrum features a mono tube design made of a high-end special ovalized 7020 series aerospace aluminum. The mono tube frame design provides frame flexibility while the premier tubing creates an incredibly lightweight frame. The Nitrum is highly configurable allowing you to tailor the wheelchair to your most precise personal preferences. There are 89 seat width/seat depth combinations with widths up to 20”. Three front frame angles are available to accommodate your leg positioning preferences. Frame inset options of 0”, 1”, and 2” allow you to taper the taper the legrests to the openness or tightness you desire.
