ErgoGlide ReliefCore lumbar cushion mounted on an office chair
Contour-fit design
Follows your spine's curve

Your chair was built for shipping costs, not your spine.

Flat cushions flatten. Cheap foam goes stiff. And by hour four, that dull ache in your lower back has settled in for the day — at your desk, in the car, or at your gaming setup.

Why it works

Designed around your spine, not a spec sheet

True contour fit

Curved core mirrors your spine's natural shape instead of pushing back against it.

High-density memory foam

Holds its shape sit after sit — it won't flatten out after a few weeks like cheap foam does.

Fits almost any chair

Adjustable straps secure it to office, gaming, car and dining chairs alike.

Breathable knit cover

Stays comfortable through long sessions, even in a warm room.

Light and portable

Under 700g — move it from desk to car to couch in seconds.

30-day comfort promise

Give your back a month to adjust. We're here if it's not the right fit.

From box to relief in under a minute
