Spinal Stenosis: What It Is—and How Smarter Sitting Can Help
Struggling with Spinal Stenosis?
If you’ve been diagnosed with spinal stenosis, you know how quickly it can make standing, walking, or even sitting a challenge. That dull ache, tingling, or weakness in your back and legs? It’s not just frustrating—it can feel limiting. While surgery or physical therapy may be part of your plan, one often-overlooked piece of the puzzle is how you sit.
Poor seated posture can significantly increase spinal compression, aggravate symptoms, and slow your recovery. But the right support can help relieve pressure and restore comfort.

What Is Spinal Stenosis?
Spinal stenosis is the narrowing of the spinal canal, which puts pressure on the spinal cord and nerves. It most commonly affects the lumbar spine (lower back), but it can also occur in the cervical spine (neck).
Causes of Spinal Stenosis
- Degenerative changes: Age-related wear and tear is the most common cause. This includes disc degeneration, osteoarthritis, and thickened ligaments.
- Herniated discs: When discs bulge or rupture, they can intrude into the spinal canal.
- Bone spurs: Arthritic changes can lead to overgrowth of bone that narrows the canal.
- Congenital narrowing: Some people are born with a naturally narrow spinal canal.
- Spondylolisthesis: When a vertebra slips forward, it can compress nerves within the spinal canal.
Common Symptoms
Symptoms vary depending on the severity and location of the stenosis, but may include:
- Lower back pain
- Numbness, tingling, or weakness in the legs or feet
- Pain or cramping in the legs, especially when standing or walking
(neurogenic claudication) - Difficulty balancing
- Relief when bending forward or sitting (which opens the spinal canal)
Why Sitting Matters with Spinal Stenosis
Although standing and walking may worsen stenosis symptoms, poor sitting posture
can also make it worse by compressing the spine and altering pelvic alignment..
Poor Posture Worsens Stenosis By:
- Increasing lumbar flexion and narrowing the spinal canal
- Creating slumped sitting, which loads the spinal discs and joints unevenly
- Causing pelvic instability, which leads to muscle compensation and fatigue
- Reducing circulation to nerves already under pressure
*Research has shown that postural adjustments and optimized seating can improve spinal loading and alleviate symptoms of spinal stenosis.*¹ ²
