Are Wedge Cushions Good For Back Pain?

You’re probably experiencing backaches and pains from sitting in the same position for long periods. A slight adjustment, such as a sitting wedge, could offer you an affordable solution to provide more comfortable working positions, which will help improve your posture while reducing pain. Please keep reading to find out about what they are, how they work and their benefits!

As a general rule, a wedge cushion will help those who suffer from chronic back pain. The purpose of wedge cushions is to realign the spine and relieve back pain caused by prolonged sitting. It is essential to design a wedge cushion with an angle between 110 and 135 degrees from the trunk to the thighs.

*This is my opinion as a chiropractor and seat designer.

Based on my 30 years of treating back pain, posture problems, and weak cores, I am writing an article on finding the perfect wedge cushion. The following tips will help you avoid low back pain while sitting. Follow my simple recommendations in this blog to feel better and avoid back stiffness while sitting.

Sitting Wedges: What Are They?

They position your body in a natural and relaxed position, helping to reduce fatigue from being seated for extended periods of time. For the best results, choose a wedge designed by an ergonomic expert or made from natural materials like latex. With the right sitting wedge, you can easily improve your posture while enjoying greater comfort throughout your day.

Sitting Wedges: How Do They Work?

The wedge cushion will make your back feel better when you sit on it. Sitting wedges improve the angle between your torso and upper legs and enhance the surface you sit on. In addition to tilting your pelvis forward, the cushion will improve your lower spine’s inward curve. Consequently, your spine may be less stressed, your back may be able to distribute your weight more naturally through your sitting muscles, and you should be able to sit more upright without straining your joints, discs and ligaments.

For your health and comfort, it is important to consider the seat angle when you are looking for a sitting wedge. The recommended range for the seat angle tends to be between 8-13 degrees, as this may affect how much strain is placed on your back muscles. Natural latex wedges are best in terms of support and durability, so make sure to keep this in mind during your search. Additionally, it would be wise to look for a wedge that was designed by a back expert or specialist who has experience with postural disorders and seating solutions. If you have never experienced this seated position, start with short periods of time to let your posture adjust gradually until your back muscles become stronger.

Why Should You Use A Sitting Wedge?

By using a sitting wedge, you can ensure that you won’t hunch over your desk. In addition to improving your appearance, it prevents back pain in the long run!

The Following Are Some Benefits of Sitting Wedge Cushions:

  • Comfortable and supportive pelvis
  • Enhanced posture
  • Engagement of core muscles (transverse abdominis, pelvic floor, quadratus lumborum, obliques)
  • Relieves low back or sciatic pain
  • Relieves pain caused by the coccyx 

A Core Muscle Wedge: How Do You Use It?

Simply place it on your office or dining chair with the slope inclining towards the front of the chair and then sit on it. Your spine will be straightened by it as you sit up straighter. Soft seating, such as a sofa or chair, is generally not compatible with these wedges.

If you are considering buying a wedge cushion, here are my recommendations:

  • An ergonomically contoured wedge cushion helps to improve your comfort and posture. 
  • 8-13 degree angle slope may work
  • High-quality base foundation foam (+96 kg/m3)
  • Soft top comfort layer (56-68 kg/m3)
  • The best overall foam for comfort, resiliency, and alignment is Natural Latex (my opinion!)
  • 4D stretchy cover
  • Non-slip bottom cover

Use a Posture Wedge Cushion to Reduce Low Back Pain

If you’re struggling with low back pain or sciatica, using a wedge cushion can be beneficial when seated. Your pelvis will tilt forward, allowing your lower spine to follow its natural curve and take pressure off of your joints, discs, and ligaments. For optimal use and comfort, the cushion should be crafted with natural latex by an experienced expert on back pain. Utilizing this type of cushion can help reduce discomfort so that one can spend more time seated comfortably and less time feeling discomfort or strain throughout their entire body.

Use a Sitting Wedge Cushion to Reduce Hip Pain

Sitting in an office chair can sometimes cause some individuals to tilt their pelvis backwards. This posture can lead to discomfort in the hips, pressure on the muscles in the lower buttocks, and nerves in the legs. A different weight distribution can result, putting more pressure on the hamstrings and tailbone. This can increase strain on the pelvic joints’ ligaments.

A wedge cushion can improve posture and alleviate discomfort. It helps distribute weight evenly from the buttocks to reduce pressure on sensitive areas in the back and pelvis, potentially reducing discomfort and aches from extended sitting.


Sitting in a chair for hours on end can take its toll. The human body is not made to sit still for long periods, and it’s common to experience backaches, soreness, or pain from sitting in the same position day after day. 

A simple solution would be investing in some ergonomic products that will offer you more comfortable positions while at work. One such product is a sitting wedge cushion that elevates your hips so that you can keep your spine straighter while seated – this minor adjustment has been shown to reduce stress on the lower back by as much as 60%.
