Purple Double Seat Cushion ($111, originally $139)

Sitting on an office chair from nine to five will do a number on your posture and back. Purple's Double Seat Cushion delivers its GelFlex Grid technology to any seating option you want. It helps cradle your tailbone, offering support and cushioning to your lower back. Place this on office chairs, dining chairs, or even in your car.

You can also consider getting this Level Up Bundle ($190, originally $238), which comes with the brand's Ultimate Seat cushion and back cushion. This seat cushion has a wider, deeper seat and a contoured groove for posture support.
