Comfort-First Cushions

Inside every cushion cover is 100% Purple Grid, for a sitting experience unlike any other.

The Grid cradles your tailbone (and even wallet!) while cushioning the rest of your seat.

Hundreds of air channels paired with a temperature-neutral material mean you're not stuck with a sweaty seat.

Engineered to bounce back and withstand wear and tear from normal use. (It's even covered by a one-year warranty!)

Premium Features

Stretchy Comfort Cover

Woven with two-way stretch, the cover flexes so you feel the full support of the Grid.

Easy to Clean

Throw the cover in the washer and clean the grid with soap and water.

No-Slip Design

A grippy bottom helps keep the seat cushion in place.
