Frequently asked questions
It's Purple's biggest and thickest cushion with 2.5 inches of 100% GelFlex Grid built specifically for larger chairs and heavier weight support. The Grid relieves pressure on your tailbone and hips instead of just padding over it, so long stretches in the same seat stay comfortable instead of numbing. The Ultimate Seat Cushion is also our pick for users over 200 lbs.
Yes, it's built for 8+ hours in the same seat, whether that's an office chair, a truck cab, or a gaming setup. The GelFlex Grid's air channels keep heat from building up underneath you, so hour six feels a lot like hour one.
The Ultimate Seat Cushion is designed to work in truck and car seats as well as office and gaming chairs, so you're not stuck buying a separate cushion for the commute. Its no-slip base keeps it from sliding around on a vehicle seat the way a flat foam pad would.
Because extreme heat can warp the GelFlex Grid material, we recommend avoiding leaving your seat cushion in hot vehicles, as heat damage may void your 1-year warranty. If you need to keep your portable Purple seat cushion in your car, store it out of direct sunlight—such as in your trunk or under a seat.
The GelFlex Grid cradles your tailbone and distributes pressure across the rest of the seat, which is where most sitting discomfort starts. Pair it with the Back Cushion for lumbar support if your lower back needs attention, too.
Every Purple seat cushion comes with a 30-day trial and return policy starting from the date of delivery, giving you time to experience the pressure-relieving comfort of GelFlex Grid in your daily routine. Additionally, our durable seat cushions are backed by a 1-year warranty to protect your investment.
The cover is machine washable on cold with a low tumble dry; hand-wash the cushion itself with warm water and a gentle detergent.
