I have had very significant discomfort for the past 7 years when sitting due to spinal stenosis and was hopeful this cushion would help (along with the epidurals etc). For the first month I used this cushion on an adjustable, cushioned recliner chair and I continued experiencing very significant lower back and leg discomfort (pain!)–and I was very disappointed the cushion didn’t help. BUT I always wait a while to write a product review until I have used the item for a while and I am very glad that I waited before writing this review. I recently tried putting the cushion on a dining room chair (wooden, straight back, no cushion chair) and eureka! This cushion really helps me!! I moved the straight back dining room chair into the living room, where I watch TV and use the computer and over the past 3 weeks it has made a significant difference. Am I cured? No…but using this cushion and a straight back chair has made a noticeable difference. Pros:. **Delivery was quick **Cushion seems strong and well made **Very comfortable to sit on (when well supported) **Company contacts you and seems to really stand behind their product **I would buy this cushion again ..More
