I can’t say enough good things about the BlissTrends 5.2-inch Thick Memory Foam Seat Cushion. I’ve tried a handful of cushions over the years, but nothing even comes close to the comfort and support this one delivers. The moment I sat on it, I could feel the difference — the memory foam is dense, supportive, and genuinely comfortable, not the cheap kind that flattens out in a week. I use it at my desk for long workdays, and it has drastically reduced my lower back and tailbone discomfort. The ergonomic design takes pressure off exactly where you need it, and my sciatica pain has noticeably improved since switching to this cushion. Long drives feel easier too; it fits perfectly in my car seat and stays in place. The thickness is perfect — luxuriously soft but firm enough to keep your posture aligned. Even after hours of sitting, it still bounces back and holds its shape. The cover feels high-quality and breathable, and it’s removable for easy cleaning. If you sit for extended periods — whether in the office, car, or even on long flights — this cushion is a game-changer. Comfortable, supportive, and absolutely worth it. Highly recommended!

I suffer from DDD and SI Joint Dysfunction and have been searching for something to put on my hardwood dinner chair since I use my kitchen table as a desk and sewing area. I was sitting on several pillows to help ease my pain, but after about 20 minutes I was done, due to intense pain. I have used this Seat Cushion now for about 5 days and I am so pleased and happy with it! I can now work at my kitchen table for about an hour at time before I need to get up and stretch and start all over again. I'm considering getting a 2nd one to put in my truck, since long trip and days when I'm in my truck driving around running numerous errands can be very painful.

I still hurt, but it should help protect my back. After my disectomy, I need this to protect my tailbone. It' too tall to work in my car. I;m 5'7" and my head hits the roof with it, so I leave it in the living room. It makes me feel like a granny, but I am, so... Oh well.

Super comfortable. I have another one that I had purchased from another highly rated brand and I think I prefer this one. It larger and thus provides more rounded support where needed, also helping with posture. The back side comes up far enough to really emphasize posture and tailbone support. I got this because I work from home and sit all day in front of a computer. This has helped reduce the discomfort I was feeling in my chair. While I still need to get up and walk around because thats the best thing to do, this was a great purchase and would recommend.

This Extremely Comfortable seat cushion I bought for my car drivers seat is beyond my hopes for this product. I have been using an inadequate cushion for a long time. Due to the severe generation of my spine I have lost 6 inches of height from my originally 5'1" frame. I searched for a 4" cushion to lift me high enough to comfortably see out. This not only lifts me beyond my seats limit but does so with extreme comfort. Thank you for this out standing product.

I have purchased similar seat cushions in the past, but I find they are so small and I’m constantly readjusting during the work day because I begin sliding off the chair. However, THIS cushion is large enough to completely take up my office chair seat and I can sit comfortably for hours! I’ve used it for two weeks and I would highly recommend for anyone! I’m actually purchasing a second one for my car!

I sit at my desk all day for work and have been experiencing a lot of low back pain. Chiropractor suggested I consider purchasing a new chair with more support- this seemed like a budget friendly alternative. I noticed the difference instantly, and am able to work at my desk for much longer periods in comfort. Was surprised how well it holds up after being sat on for hours at a time- seems to hold its shape and its ability to support very well.

After six months of testing two of these cushions, I'm still very happy. Price was under $25 but has jumped in recent months to $31. I have not washed these yet but they are saving my sciatic nerve and fending off my spinal stenosis. I can't imagine sitting on regular computer chairs ever again without one of these. Great product. Thank you BlissTrends.
