- thewhoFirm, supportive, and perfect for sciatica relief — worth every penny!Based on my own purchase (I don’t receive free items to review), I can honestly say I love this cushion! I have sciatica, and sitting used to be painful — but this has made a huge difference. The firmness is just right: supportive without feeling too hard, and it keeps its shape even after long hours of use. I’m about 175 lbs now and fit perfectly, but I also used it when I was around 220 lbs and it worked great then too. It’s lightweight, easy to move from my desk chair to the car, and even comes along on trips because I can’t go without it. My husband tried to borrow mine on a recent trip, so I just ordered him his own. Excellent comfort, size, and quality — highly recommend!
- Judy L.Has helped so much with pain caused by old couch cushions. Better than others I tried.We eat dinners in the family room while watching a movie and sit on an old couch with a coffee table that raises to table height. I am 77 years old and sitting on the worn and flattened cushions of the couch was causing pain in my hips so that it was difficult to walk for a bit when I got up from the couch. By the end of a 2-hour movie, my legs were uncomfortable, beginning to ache, and felt like the blood supply was cut off from them because the couch cushion flattened so that the frame of the couch was hitting the back of my thigh.
Since we haven't found time to get out to find a replacement couch, I turned to Amazon to find a temporary solution. I ordered this "butt cushion" in addition to 4 others in hopes that one of them would relieve the discomfort of sitting on our couch. I wanted something firm enough to overcome the flattening of the old couch cushions, but, it trying the different cushions, I found that shape and size is also important. Since I weigh 112 lbs., most of the cushions I ordered were firm enough, but the support offered by each was different. Some flattened after a short time, and some just weren't very comfortable because of the shape.
This cushion is more expensive than the others I tried, but saving money at the expense of less comfort wasn't an option. I have been using this cushion every night for over a week, and no longer have the hip pain when I get up from the couch. The leg discomfort is also gone. The 4 other cushions have been returned. Since I weigh 112 lbs., I can't vouch for how this cushion would hold up to more weight, but it works for me and I am happy with it.
UPDATE 07/30/24:
I have been using this "butt cushion" every evening for at least 3 hours for the last 2 months, and I wouldn't want to do without it. In this time, it has not flattened at all, is very supportive, and perfectly fits the contour of my butt and thighs so I no longer get pains in my hips and legs from sitting on our old couch. You would think that finding a suitable cushion to sit on would be an easy task. In my experience of trying different cushions, I found that the perfect cushion is a very personal thing. Not only does it have to supply a comfortable firmness for support, but it must conform to your individual "butt contour". It is often necessary to try more than one to find the one that is perfect for you. This cushion is all that for me.
UPDATE 12/16/24:
I have now been using this cushion on my couch to sit on for over 6 months. It is still as supportive as it was when new, and has not flattened at all. Since using it, I have not had pains in my hips or legs after sitting on the couch. The cushion is so comfortable, we have put off getting a new couch. I suppose this is the only down side to having a comfortable cushion to sit on.
I hope this review was helpful for you. - AndyA Game-Changer for Desk Workers: The C CUSHION LAB is a Must-Buy!I purchased the C CUSHION LAB Patented Pressure Relief Seat Cushion a few weeks ago out of sheer desperation. As someone who spends 8+ hours a day at a desk, the discomfort, especially lower back pain and a persistent ache in my tailbone, was becoming unbearable, even with a supposedly "ergonomic" office chair. After trying this cushion, I can honestly say it's completely transformed my workday.
The patented pressure relief design is not just marketing—it's genuine engineering. The contoured shape cradles your hips and thighs perfectly, but the true magic lies in the U-shaped cutout at the back. This feature entirely eliminates pressure on the coccyx (tailbone), allowing you to sit properly without sinking into a painful position. It promotes a healthier posture naturally, and within minutes, I felt the tension melting away from my lower spine.
Unlike many cheap memory foam cushions that flatten out after an hour, the C CUSHION LAB maintains its shape and density throughout the day. The high-density foam provides the perfect balance of firmness and soft cushioning. It feels supportive enough to keep you upright but comfortable enough to forget you’re even sitting on a cushion. The cover is also high-quality, durable, and easy to remove for cleaning, which is a big bonus.
Whether you're dealing with sciatica, recovering from an injury, or simply seeking an upgrade for long-haul sitting (at the office, in your car, or at home), this cushion is an investment in your physical well-being. Don't hesitate—if you want to sit comfortably again, the C CUSHION LAB is the best purchase you can make. It truly lives up to the hype! - James NorthIt's worth itWorks as aspected and maybe even a little better.
it's actually comfortable and if they paid me I would definitely endorse and or advertise their product.
Being a 56 yr old male 350 lbs with edma and eczema this cushion is a great help. - Katherine JohnsonWorth the money!I have had recurring tailbone pain for years, and have bought several other tailbone cushions over the years. They never really worked, and I would still get pain after sitting on them. I kept seeing ads for Cushion Lab's cushions and figured I would give one a try, so I bought this one. I have been using it for 2 months now and I am so impressed that it actually works! I can really feel a difference in this cushion, and I think a big part of it is the shaping. I didn't want to spend the money, because this cushion is pricier than the flat cushions, but it actually works. I use it in my car and move it to my desk chair, so I probably will end up buying a second one to keep at work. This cushion is totally worth it, and I have not had any pain while using this cushion!
