Hip OA and sacroiliac joint pain are exacerbated by sustained sitting on flat, hard surfaces. A seat cushion that redistributes pressure away from the greater trochanter (hip bone) and reduces pelvic tilt can meaningfully reduce pain during sitting. The best designs use a coccyx cutout or contoured foam to reduce direct pressure on the painful structures.

Carex Lumbar Support Cushion

Best combined lumbar + hip support

For people with both lumbar OA and hip OA, a combined seat cushion with lumbar support pillow addresses both simultaneously and is particularly useful for car seats and office chairs that offer minimal built-in support.

Arthritis Supplies Rising Chair Aid

Best for sit-to-stand difficulty

For people with hip and knee OA where rising from a seated position is particularly painful, seat lifting aids (electric or spring-assisted) change the standing-up mechanics to reduce peak joint load. A frequently overlooked intervention.

Carex Foam Seat Riser

Best for low furniture

For hip OA patients, deep-sinking soft sofas are more painful than firm, elevated seats. A firm foam seat riser placed on top of a couch or chair changes the hip angle to reduce impingement. Simple, inexpensive, and highly effective.

Where to start

For most people with hip OA or tailbone pain: start with the Carex coccyx-cutout cushion for your primary sitting surface (desk chair or car). Then address the sofa with a seat riser if deep sinking is a problem.
