See real people enjoying lasting comfort and support with Aliner™ Cushion in every setting.

Sit Better, Feel Better

End Tailbone, Sciatica, and Back Pain When You Sit
Most chairs break your body down in less than 30 minutes. Your hips roll forward, your spine caves in, and pressure builds on your tailbone and sciatic nerve. That’s why long commutes, office hours, or even sitting at the table can leave you stiff, sore, and numb.
Aliner is designed to stop that. The coccyx cut-out lifts pressure off your tailbone, while the built-in lumbar rise fills the gap at your lower back to restore natural posture. High-density memory foam distributes weight evenly across hips and thighs, keeping circulation flowing so your legs stay energized instead of going numb.

Improve Posture & Boost Circulation
Car and truck seats are built tough, but never with your body in mind. Their bucket shape drags your hips down and presses your thighs into the cushion, choking circulation and leaving your legs restless. With time, this posture collapse strains nerves and leaves you sore long after the drive is done.
Aliner is crafted for endurance. The leveled base keeps hips aligned, contoured edges ease thigh pressure, and the lumbar lift supports your spine mile after mile. The result? Strong posture, steady circulation, and pain-free comfort no matter how long you’re on the road.

Support That Fits Every Seat
Aliner works anywhere you sit. The steady base and non-slip bottom keep it firmly in place on car seats, office chairs, dining chairs, and wheelchairs for all-day relief. High-density memory foam molds to your body without losing shape, while the removable, machine-washable cover keeps it clean and ready every day.
