ReliefCore seat cushion with back support on a black mesh office chair at a white desk

An office chair cushion with back support

A separate seat cushion and lumbar pillow drift apart through the day. ReliefCore keeps both in one piece: push it against the backrest, sit down, and the raised rear lip sits behind your lower back in the same place every time.

The side contours guide your thighs into position.

ReliefCore seat cushion with back support on an upholstered armchair in a living room

For dining chairs, armchairs and wide car seats

Set it on a dining chair, an armchair or a wide, flat car seat. The non-slip underside helps keep it where you put it.

In the car, install it while parked and adjust your driving position before you set off.

Questions

Will it fit between my armrests?

Compare the width under Size & weight with the space between your chair's armrests.

Does the back support come off?

No. The seat and the back support are one piece, so their position always stays the same.
