Frequently asked questions
What does the Back Cushion do?
It's molded 100% GelFlex Grid shaped to fit the natural curve of your lower back, so you get lumbar support instead of just leaning against a flat seat back. It's designed to encourage better posture whether you are sitting for a few minutes to answer an email or a few hours in the car.
Do I need a specific seat cushion to use it with, or does it work with any chair?
It pairs with any Purple seat cushion, but it also straps onto most chairs on its own — office chairs, car seats, and more — using its built-in strap-and-buckle design.
Is the Back Cushion good for the car or for travel?
Yes, it's built for the office, transportation, and gaming, so it works whether you're commuting, on a road trip, or at a desk. The strap keeps it in place on a car seat instead of sliding down.
Does it help with lower back pain from sitting?
The Grid is molded to the contour of your lower back, giving it something to actually rest against instead of a flat surface. That targeted support is what helps reduce the fatigue that builds up from hours in the same seat.
Will the strap fit my chair?
The adjustable strap-and-buckle design is made to fit most standard office, gaming, and car seats, with plenty of strap length to adjust to most chairs. If your chair has an unusually shaped or narrow seat back, check the dimensions (15.75" x 9.25" x 2.5") against your chair before ordering.
How do I clean it?
The cover is machine washable on cold with a low tumble dry; hand-wash the cushion itself with warm water and a gentle detergent.
What's the trial period and warranty?
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.
Is the Back Cushion FSA/HSA eligible?
Yes, Purple seat cushions are FSA/HSA eligible. Select Truemed as your payment option at checkout to use your card like any other form of payment.
