C CUSHION LAB Patented Pressure Relief Seat Cushion for Long Sitting Hours on Office/Home Chair, Car, Wheelchair - Extra-Dense Memory Foam for Hip, Tailbone, Coccyx, Sciatica - Light Grey

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.

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!

Ordered both the seated cushion and lumbar support due to lower back pain due to my desk job. I just received them today and I have to say they work great! It feels like I’m sitting on my couch while I work. Very comfortable and I feel well supported. No back pain. Thankful for this purchase and highly recommended.

This item was a gift for elderly person, unfortunately, they felt it hard and high for their comfort as their rear-end has very little glutes. I felt the cushion to be of good quality in thickness, ease of use, and comfortable.

I made the mistake of buying a cheap gaming chair and it was super uncomfortable and painful after not sitting for very long, the cushion lab seat cushion and lumbar pillow are amazing and have made my chair comfortable. The pillows are a very high quality memory foam and feel great.

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!

A nice cushion for extra support. My husband is thin and often complains about his backside when sitting. This cushion offers good support, is made just right to alleviate pressure, and makes sitting much more comfortable. The cushion fits in the car seat, at the dining room table, and anywhere else one might be sitting. It is the right size for most anywhere.

This cushion (and the back rest) saved me money from having to buy a desk chair. The desk chair in the room I am now in was so uncomfortable I couldn't stand to be in it more than 30 minutes at most - my back hated that chair, so did my old piriformis injury--even getting up a lot and moving around as I do, this chair was simply awful. I stumbled on an ad for these cushions and decided to order from Amazon, even though amazon is becoming iffy on some things, like why did the cushion come in a box but the back support did not? Was it returned and sold again - ew - you can never trust Amazon anymore to know quality control or the newness of something. This seat is high so I have to use a foot rest but I had one any way since I'm only 5'2". it molds to my body. I'm about 117 pounds and I have plenty of room. It fits on the chair so there's not very much overhang, and this chair is not very big. It's cushiony but not soft, supportive. My back pain and leg pain were relieved by 85%-90%. And if I get up plenty of times, sometimes I have no pain (this is with the back support, so note that). Function wise, it does what I need it to do. It's sturdy, helps with pain relief, and comforts to my body instead of being a hard flat surface. It is not pleasing to look at - since I have to look at it every day, I wish I could cover it up with something else - bleh. Or I wish I had ordered both pillows in black - the grey does not look good and sticks out in a way I dislike - that's on me; should have returned and ordered the black.
