ChairSmarts

The right wheelchair part, explained in plain language.

ChairSmarts helps wheelchair users and the people who help them figure out which parts fit, when it's time to replace them, and how to keep a chair rolling smoothly.

What ChairSmarts does

Wheelchair parts can be confusing. A caster, a tire, or a cushion cover might look right in a photo and still not fit your chair. Spec sheets are written for dealers, not for the people who actually use the chair.

We take that technical information and turn it into clear, step-by-step help:

  • What to measure before you order a replacement part.
  • Where to find the size that's already printed on your chair or old part.
  • Signs a part is worn and worth replacing.
  • Where to buy it, from medical-supply stores with good reviews.

Whenever we share a number or a safety fact, we link to where it came from.

Who it's for

ChairSmarts is for people who use a wheelchair, and for family members and caregivers who often end up doing the research and the ordering. You don't need to know any technical terms. We'll explain them as we go.
