Adjustability: One Product That Changes to Fit

Adjustability builds movement into a product so it can change size or form to match different users.
Instead of fixing one shape and hoping it suits everyone, the person sets the fit, as with a sliding car seat, a raised chair backrest, or an ironing board that locks at several heights.

Definition

Adjustability

Adjustability is the ability of a product to change in size or form to suit a wider range of user sizes or percentiles, improving comfort, fit, and usability.

Why Adjustability Works

Adjustability avoids anthropometric mismatch, where a product's fixed dimensions do not fit the person using it.
One adjustable unit can span a wide percentile range (see A1.1.3), so a single design serves both the 5th and 95th percentile user without a separate product for each.
The movement can be driven by mechanical, electrical, pneumatic, or hydraulic means.

Payoffs
1. One product serves many users, cutting the cost of making and stocking separate versions.
2. Users tune the fit to their own preference.
3. The product keeps working as needs change, so it lasts longer.
Trade-offs
