    5.0 out of 5 stars Has helped so much with pain caused by old couch cushions. Better than others I tried.
    Reviewed in the United States on June 15, 2024
    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 was pleasantly surprised, when I took it out of the box it felt hard and unyielding. I put in on my work chair overnight and the next day started to use it. I’ve been working from home since before COVID so the cushion of my chair left my bum numb after a while. I also have sciatica and back issues.

    No more numb bum! My sciatica is happy! For such a stiff support it does what I needed. I can now work with pain relief.

    The cushion fits just right in my chair. While yes I do sit a bit higher, it’s a minimal adjustment.

    I’m curious on the longevity of the cushion, as I still have 3 years of working from home until retirement. If this cushion can last that long it was money very well spent. But frankly, with the relief I’m getting, it’s already money well spent.

    4.0 out of 5 stars Better Solution to Buy a New Chair
    Reviewed in the United States on January 14, 2025
    I had been circling around getting a new office chair. I work from home and the price of the ergonomical chairs are pricey. I saw the cushion as a possible solution and bought on a whim, not expecting too much a difference.

    My current office chair is from IKEA and was semi comfortale to being with. Over time, because I work from home, the seat cushion began to get flat and was difficult to sit in for long periods of time. Coupled that with being 8 months pregnant.

    This cushion really surprised me! It absolutely transformed my chair into a more comfortable office chair. WAAAy more comfortable!

    The only thing stopped me from giving it a 5 star is the packaging. It comes folded in a small box. So when you open it the seat cushion is bent. I a few sittings and I think it will shape to what it's supposed to be. But I thought that was an odd choice for packaging a product like this. Where as, I purchased the seat back and the foot cushion in the same brand and they both came unfolded in their packaging.

    5.0 out of 5 stars Best cushion EVER! ❤️
    Reviewed in the United States on December 28, 2024
    I bought this to use in my car for long trips. Worked perfectly. Then I used it on a chair that I can’t sit comfortably in for kore than an hour. Sat using it for 4 hours today without amy discomfort. I park my car in a lot rather than in a garage. The weather has been below freezing so when I got into the car it was pretty solid from the cold temps. But it warmed up quickly and wasn’t a problem. I nevwr gave it a thought. Duh! ???? Am buying another one to use in my stitching chair in the house and the slip resistance will be a key plus factor. Wonderful! Gives great support and the shape is perfect.

    I already feel better in my hips and my legs. I just got this today and I already love it. This may be exactly what I have been needing. I would definitely recommend this for anybody with back and hip and leg pain. This cushion is made very good, great quality and it is pretty large and thick not anything like you buy at Walmart or other retail stores. Sure, it is a bit pricey, but it is worth every penny if it helps lessen your pain and already, I feel better, and my pain is less when sitting.

    This pillow has greatly improved my life. I was recently diagnosed with a herniated disc at L5 S1. Sitting was extremely painful until I ordered this. It has made working at a desk job and even riding in a car so much better!! If you’re suffering from disc issues or sciatic, this will be your new best friend!

    5.0 out of 5 stars Great seat cushion for a secretlab
    Reviewed in the United States on January 4, 2025
    I was slightly skeptical considering I saw quite a few people mention it was too firm. I would suggest ignoring all of these comments.
    I bought mine for use on a secret lab omega chair. Issue it with secret lab chairs while they are amazing chairs the padding on the bottom where you sit is uncomfortable and probably one of the worst parts of the chair, this cushion works perfect, fits almost perfect, and in my opinion makes the chair complete.
