A sitting wedge seat cushion helps you to sit better by raising your hips to slightly above your knees.  This naturally helps to create the inwards curve to your lower back and reduce strain on your spine.  As you sit more upright you will also reduce excess strain on your upper back too.

When you sit in a more upright way you will be using your stomach/core muscles more this could mean that you feel achy when using a sitting wedge cushion at first.  If this is the case persevere as this is just what you back needs to strengthen and reduce back pain over time.  Gradually increase the amount of time you sit on your wedge for.  Just like any exercise your body will adapt and you will begin to easily sit on a wedge and experience its benefits.

As you will be sitting slightly higher on a sitting wedge seat cushion make sure that your chair or seat height is still correct so that you have both feet placed firmly on the ground.

In addition check your set up if you are working at a a desk or computer to make sure that you are still at the recommended height in relation to your computer screen and keyboard.

  1. Really pleased with this – it changed my posture within days, makes sitting a lot more comfortable. It’s firm.

  2. Excellent product. I ended up buying two to help recovery from a total hip replacement. They are ideal for dining room types of chair and I used one for a few weeks in the car as well, but they are very firm and I have gone back to a softer cushion in the car now I am driving again to soften the affects of pot holes.

  3. Slightly more expensive than others but I wasn’t disappointed it’s firm enough to do it’s job and I use it all the time when sitting.
