No truck seat has a tailbone cut-out. New seat or half a million miles on it, by hour six the foam stops mattering and the tailbone takes over. This one is built for the seat you sit in: the width of an air-ride cushion, firm foam that holds up under any driver, and a cut-out where it counts.

Why not memory foam alone
Memory foam feels great in the store and on day one. On its own, ten hours a day under a working driver, drivers told us it goes flat. So ours uses it only as the top 1.2 in. Under it is firm high-resilience foam, the family of foam truck seats are made from, with a cut-out your seat does not have.
It will feel firmer than the cushions you have tried. That is the point.
Who it is for: anyone who sits 8 hours and up. Owner or company truck, new seat or old, any size of driver. For anyone whose tailbone, hips or the backs of the legs have opinions by hour six. If ten hours in the seat leave nothing to complain about, it is not needed.
Measured in real cabs
What we measured
We measured six real truck seats with their drivers: Freightliner Cascadia, two Volvos including a VNL 760, International ProStar with a National NS 2000, Kenworth W900L with a Sears Atlas II, and a Sears Elite 80. The flat part of those seats is 11 to 14 in. The seats are 21 to 24 in wide and 18 to 20 in deep. That is why the cushion is 11 in wide at the bottom and 19 in on top.
How we are building it
- Asked 530 drivers what wears them out. Read 1,600 one-star reviews of the cushions you already bought. Wrote down where they fail.
- Took the spec to the factories that make foam for seats, not the ones that make pillows.
- The first cushions go to working drivers in their own trucks. What they say decides the final version, and it goes on this page, uncut.
Questions drivers ask
Will it raise me so my armrests do not work?
Will it bottom out under a heavy driver?
Does it get hot on a 10-hour day?
Will it slide on a vinyl air-ride seat?
Will it fit my seat?
When does it ship?
What if it is not for me?
