Seat comfort, bought for the problem you have
Foam vs gel vs air, five cab-first fit checks, and three ranked cushions with research-based scores. Updated September 2026.
Five fit checks
Measure the cab before the cushion
Buy for your problem, not the product page.
Seat width
Measure your air-ride seat pan. A cushion wider than the pan hangs off and rocks on bumps.
Cushion height
Every inch of foam is an inch of headroom gone. The ComfiLife’s 2.8 inches is the one to watch in low cabs.
Stability
Non-slip base or straps keep the cushion centred through 8–11 hour days and frost-heaved highways.
Material
Memory foam cradles; gel pulls heat away in summer; air lets you tune firmness. Pick for your climate.
Cover
A removable, washable cover survives cab life. Charcoal and dark covers hide January grime.

Methodology
How we score
Research-based. We did not test these hands-on. Scores come from published specs and driver reviews, and a product is never called tested unless it was used in a truck cab.
Each cushion gets one Field score out of 20, weighing cab fit, materials and value for Canadian drivers. Scores are provisional and identical on every page of this site.
