      Worth every penny

      I suffered a broken tailbone and a ruptured disc four months ago, and suffered quite a bit. I had a cushion that was supposedly for coccyx relief, but when it's broken you can tell if it's true pretty quickly. It wasn't. A nurse friend of mine sent me a different one that she happened to have an extra, and while it was better, it was still not getting the job done because it was too soft and I would end up just smooshing my bum into the chair again. So, after doing a little research, I came across this Cushion Lab pressure relief seat cushion (large size). The reviews were quite good. I was a bit put off by the price at first, especially since I haven't been working due to the injury. Eventually I couldn't stand it (more accurately I couldn't sit it) anymore and decided to go for it. After two days of using this cushion, I was able to cut back on my medications and had doubled the amount of time I could sit. It's also done wonders for my arthritic hips which was a pleasant surprise. The sciatic nerve pain is also better (at least until I get up). While I'm still healing, I feel like I can finally get back to work so long as I have this cushion under my tushy. Only time will tell how well it holds up, but even after my physical woes are over, I expect to keep using this cushion as all the relevant body parts just feel *right* while sitting on it. My advice: just get this cushion from the get go - it'll be worth every penny in the end.

      Where have you been?

      I have only had this seat cushion for over a month and it has helped my sciatica and low back pain on my right side. I bought this to replace the cushion I had on our dining room table because after what was only several weeks, the cushion went from very supportive to not and I was in extreme pain that I couldn’t even sit down to have a meal for too long because the pain in my low back had become so unbearable that no matter how I adjusted myself while sitting, nothing worked. I can’t even tell you honestly how I found Cushion Lab…I think I went on google and just searched top seat cushions looking for Purple as I saw on an ad that they now have a seat cushion and was curious about it. Instead, I ran into a link for Cushion Lab and through my desperation, I went to see what they sold. I saw this cushion and read the reviews and looked promising. I told my husband about it and he said try it out so I bought it and I’m so glad I did. The moment I got it, opened it, and used it; the pain in my sciatica has decreased when I sit on this Just yesterday (April 6), my right side was on fire and really angry to the point where I couldn’t even stand. So I went to my dining room chair where this cushion is on and sat there for a few minutes and I went from wanting to cry in pain to relief. After 5 minutes of sitting on this, I was able to stand up and finish up a few small chores around the house. My husband has seen how it has helped me and he has been having these weird low back and hip pains as well that he asked me to get him one to try out. He’s 6’1” so I got him the larger size. I love how firm the product is because that tells me the support will stay firm for a very long time. The other plus is the grippiness of the cushion. We have wood dining room chairs and this doesn’t slide around on my chair. My only issue (which is not a deal breaker) is that since I’m 5’1”, it’s ever so slightly tall when I need to sit on it so I almost have to come at it from the sides but once I’m on it, I am comfortable and pain-free. I know for someone who’s going to read this very long post and think it’s a hype. It’s not…I don’t leave very many product reviews because not all products are created equal. But this product is legit! Do I still have my low back pain and sciatica pain? Yes, but this has helped managed it and I’m so glad I got it.

      I sit - a lot

      I work twelve hour shifts in 911 dispatch center where you sit all night. I have only used the cushion lab cushion once but it made a huge difference. My bum and back both felt better than usual by the end of the night!

      A year ago my husband fell and injured his tail bone. Ever since, he has had a difficult time Sitting for any length of time. We have bought all types of cushions, but none have helped. I saw your product and hesitated because of the cost. Then I remembered the old saying, "You get what you pay for". It's true! Your product has been a God send. My husband has no problem sitting any more. Thank you so much!

      10 star rating!

      I drive the school bus. I have scoliosis, and a spinal fusion. My back loves these cushions. I’m lucky enough to own two of them. My back pain is less after driving with it on my school bus for a week!
