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!

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.

this pressure relief seat cushion truly deserves five stars and more. From the moment I sat on it, I could feel the difference. Whether you're working long hours at a desk, driving for extended periods, or just need extra support at home, this cushion delivers unmatched comfort and support. The ergonomic design is fantastic — it promotes great posture and helps evenly distribute weight, which has drastically reduced the pressure on my tailbone and lower back. I used to stand up with stiffness and discomfort after sitting for a while, but now I can go hours without any pain or fatigue. What really impressed me is the quality. The memory foam is dense and supportive but still plush enough to feel luxurious. The cover is soft, breathable, and easy to clean — a thoughtful bonus that adds to the overall value.

The C CUSHION LAB Seat Cushion is more comfortable than the Egg Sitter cushion I bought from Grommet. Of course, it is more expensive. A bit difficult to get it placed just right in my recliner. It does provide some relief from pressure on my tailbone. So far, it is the only cushion I have found that makes sitting more comfortable. I recommend.

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.

I have a desk job so I’m sitting for most of my 8 hour shifts. I did my research before deciding what brand to buy and the research paid off big time because this has been a life changing purchase for me. Now I did buy the seat cushion, the lumbar support, and the footrest all at the same time and literally on the first day of use I was finally able to leave my work shift without a sore back and numb feet. This is soft yet firm and lightweight enough to travel with. My sleep quality has improved because of no longer creating back and leg pain all day at work.
