Posture Wedge Cushion – Relief in Sitting


An ergonomically designed orthopaedic cushion, the posture wedge cushion is an angled seat wedge cushion that can be very useful for reducing hip and pelvic pain in sitting. This cushion helps to redistribute loads around the hip and pelvic joints, muscles, tendons and nerves, all of which might contribute to hip and pelvic pain in sitting.

Portable and lightweight, the posture wedge cushion can go anywhere with you, easing your sitting pain and saving you $$$ on ergonomic chairs. 

Reduce hip pain in sitting by using a posture wedge cushion

Many seats, particularly lounge chairs and car seats, force a sitting posture where the knees are higher than the hips. Sitting for prolonged periods with the hips bent more that 90 degrees can irritate painful conditions at the front of the hip, such as labral tears, osteoarthritis, femoroacetabular impingement and hip flexor related pain. Sitting in this position can also irritate pain around the side of the hip associated with gluteal tendinopathy or trochanteric bursitis (greater trochanteric pain syndrome). Using a posture wedge cushion lifts the hips higher than the knees, opening the front of the hips and relieving tension around the side of the hips. For many people, this can be an excellent tool for reducing hip pain in sitting.

Reduce pelvic pain in sitting by using a posture wedge cushion

Whether sitting in a low or normal height chair, some people naturally tend to sit with the pelvis rolled back quite a long way. This can alter where the pressure is distributed, but also the stretching forces around the back of the pelvis and the lower back. Sitting with the pelvis rolled back usually shifts the bodyweight further back. This places more pressure under the back of the sitting bones and the coccyx (the tip of the tailbone). Such sitting postures might increase tenderness of the hamstring tendons that join into the sitting bones, or pain in the coccyx region (coccydynia). Using a posture wedge cushion can reduce sitting pain in these situations by encouraging more even weight redistribution. For those with coccydynia, a cut out in the wedge cushion might also be required. A coccyx cushion is specifically designed for this purpose.

With the pelvis rolled back in sitting, there will also be more pressure on the muscles of the lower buttock and the nerves that pass through the buttocks and down into the legs. Pain associated with irritated nerves in the buttocks (Piriformis syndrome, Deep Gluteal Syndrome, Pudendal Neuralgia), may be aggravated when sitting for longer period in these postures. A posture wedge cushion can often assist in reducing nerve pain in sitting.

Sitting with the pelvis rolled back also increases the strain on certain ligaments of the lower back and pelvic joints. These forces are normal but if you are experiencing pain in the lower back or sacrum region in sitting, altering these forces can assist. A posture wedge cushion helps tip the pelvis a little further forward to take some pressure off sensitive ligaments, reducing back and pelvic pain in sitting.

Reduce muscle pain and fatigue in sitting by using a posture wedge cushion

If you are naturally more flexible than others, you might have a tendency to sink into these more extreme ‘slouched postures.’ Working hard all day to hold yourself in more upright postures can be extremely fatiguing and become painful. The aim is to use the minimal amount of effort in sitting – to find a relaxed position where the body weight is well supported. By using a posture wedge cushion and ensuring you are sitting against your chairback, you can relax and allow the chair and your cushion to do the heavy work. The posture wedge cushion can then allow longer periods of sitting by reducing fatigue and muscle pain.

A posture wedge cushion or a new chair for pain in sitting?

While it can be helpful for some people to invest in an ergonomic chair, this doesn’t solve the situation for those who need to work in different workplaces and for those who get pain in the car or during social outings. Unlike a chair, you can take the cushion anywhere with you, on planes, in cars, to the theatre and movies – wherever you get pain in sitting.

Scared to catch up with friends or go out to dinner because of your pain?  The posture wedge cushion is so light and easy to take with you. Now you can enjoy your time out everywhere!


Setting up your posture wedge cushion on your chair, to reduce hip and pelvic pain in sitting

At work and at home just set up your chair to have your knees and hips at 90 degrees and then place the cushion on top. This automatically lifts the hips to be just higher than the knees, allowing the hips to open up and the pelvis to sit in a more supported and relaxed position. You may need to slightly adjust your lumbar (low back) support, as you are now sitting a little higher in your chair.  And that’s all you have to do – it’s that easy!

Some of the more common conditions in which a posture wedge cushion may reduce pain in sitting:




I used my angled cushion before and after my hip replacement surgery. I gave me the confidence that my hip was above my knees after the operation when I was sitting



I have pain in my lower back buttock and front of my hip. I would be unable to sit and to drive if it was not for my posture wedge cushion. It has changed my life with how I am now able to get out and about and travel and socialise.
