Review: 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 desertcart 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.
Review: Great relief, worth the price, get it. - Great for standard work task chair. The quality is great. Saved me from the standard corporate chair that has been sat on before by more than a few people, I am guessing. I don’t care if people in the office see it as it is a good looking cushion. Just adjust as needed. It’s Comfortable and helps with back and hip strain. It’s heavy, not flat, holds its shape but a nice soft give where you need it. Fabric is nice. Get it.

## Questions & Answers

**Q: How does the cushion come boxed? (The box packaging) It's for a gift. Does someone have an image they can share, please?**
A: It comes in a brown cardboard box.  The pillow is squished into a plastic bag.  You must wrestle the pillow from the bag and allow to sit and fluff up.  My advice- buy something else.  This was gifted to me on Monday.  Under 140 pounds, sat on it for 5 minutes.  The pillow was flat and I could feel my tailbone touching the seat through the hole in the cushion.  They do not provide an invoice, packing slip, info on how to return or who this was a gift from.  I emailed twice- no reply.  Rcvd a c/b a few minutes ago but they can’t find any info for my pillow.  I sure how to return.  This item is way too expensive for what it is and it doesn’t do what it says.  I am so appreciative to be thought of and that someone is willing to spend this much on a special pillow to help me but this pillow is a fail.  I was sent the seat cushion and lumbar pillow.  The lumbar pillow hasn’t really been tested much (I’m not over the moon about it).

**Q: How is the seat cushion for bigger people, 6'6" around 380 lbs? Will it hold?**
A: I am in a similar category - 6'5'  ~ 350 lbs -- I did not like it -- it is too small -- it hits my legs in the wrong place -- and ( for my liking ) is NOT wide enough ....it requires constant adjustment to remain comfortable

**Q: The photo says 16x16x3, the description says 15.5 x 18 x 4 inches. Which one is correct?**
A: I found the dimensions for standard and large sizes per the manufacturer:

Standard: 18 W x 15.5 L x 4 H inches 
Large: 21 W x 18 L x 5 H inches

**Q: Has anyone tried it on a couch? i’m in my 70s and finding i have lower back pain after i’ve been sitting on the couch. hard chairs are fine**
A: I have 5 lumbar (& 5 cervical) vertebrae which are messed up in multiple ways.  I’ve found a good lumbar support cushion helps more than a seat cushion support. That said, it doesn’t matter how many different types of lumbar supports (with or without a seat support—I have tried many), that I try or use, if the chair or couch I am sitting in has lost its firmness/support, or was just too soft and not well-supporting to begin with, I will still have pain—even with the addition of constant heating pad use.  I had a very nice Lay-Z-Boy recliner (though I never use the “recline” feature—it is more comfortable for me to have a rocking recliner and use an ottoman so I can keep my knees bent, and provide more relief of my lower back at the correct angle for me).  When my back pain got considerably worse, my recliner was about 6 years old.  I paid several hundred dollars for a Laz-y-Boy repair man to reinforce/replace the springs in it and replace the foam cushions.  That, plus a lumbar support pillow and heating pad, kept the recliner usable for me for about another 4 years.  Then, I decided to just buy a new one.  I bought another Lay-Z-Boy, but still use a lumbar support pillow (one that goes as high up on my back as I could find: 17 inches), & of course, a heating pad about 80% of the time.  I found trying to use a seat support on my new chair caused me to sit too high in it, and all the support it provided was hitting me wrong.

I guess my point is: these types of supports can definitely help (depending on how severe your spinal problems are), or enable you to extend the life of a chair you like, but at some point, you may need to upgrade whatever you’re sitting in, and shop with back support as your top priority.  Also, just like with mattresses: stay away from “all memory foam” construction.  It breaks down over time and becomes a spongy mess.   Look for good old fashioned firm spring support, though it is usually more expensive.  You can always buy a memory  foam topper for it—and when it becomes flat, just replace that!

### ⭐⭐⭐⭐⭐ Nice chair cushion! Makes me want the pillow too
*by A***R on February 9, 2026*

I like it a lot! Really helpful with tailbone pain, leg discomfort and with lower back alignment. Springs back to shape well and the size are great even for a plus size person. It's functionally weighted with grippy nubs so it won't dance off of your chair. It's flat enough to not be intrusive.
