Frequently Asked Questions

Q. Being as light as 7.5 kg , can the Quickie Nitrum accommodate plus sized users?

Ans. Why not? Even though the Tiga Sub4 weighs only 7.5 kilograms, it can still accommodate users up to 125 kilograms. 

That’s because every single part is made taking the unique measurement of the user itself. So, don’t worry if you’re plus sized, the Quickie Nitrum will be your buddy.

Q. Is the Quickie Nitrum suitable for travel?

Ans. Yes, it is! Just use the Twist Lock bar to release, fold, and load the chair into your car. The ergonomic grab bars with rubber grips reduce wrist strain and make lifting easier. Removing the rear wheels opens the underside of the frame for easy car transfers, all without removing side guards or cushions.
