My 7 year old couch cushions were worn out and I have tried a few other foam pads but non had the firmness while being comfortable until I bought this one. I bought 1 and cut it to fit in my couch cushion covers. No longer sinking into the bottom of my couch and this saved me from having to replace my couch. Well worth every penny spent, would buy again.Perfect for what I needed. It is rolled and pressed tightly to ship. Open it immediately, fluff the foam (especially the edges), and let it fully expand before laying or sitting on it.Foam was delivered in 2 days, rolled up tightly in box. After 10 minutes, it was fully expanded. Lies flat, no odor, clean and provides soft cush for tush on window seat.There has to be a better way to shrink wrap the foam. I was able to cut the two cushions I needed from the large foam sheet. It took several days to fully expand enough that I could cut it. There was about 2 feet left over that I didn’t need, but the corner of that leftover sheet never fully expanded. It’s been months and it has not expanded, so basically it never will. I just think if you expect to use the whole foam sheet you might be disappointed that it might not expand completely. I did everything recommended to get it to expand and it didn’t work. Just a heads up to the company, you gotta rethink the packaging. If a person pays for the whole foam sheet they should get a whole foam sheet, whether they use it all or not.It was more comfortable than what I had, but I would have liked it if I could have got it in my right measurements!I got a 5 inch high density foam and it works great for my van life bed/bench. I do have to mention it took about 2 days for it to almost completely rise to its supposed size, however, the end on one size didn't fully rise to a complete 5 inches but I'm not picky because it's now covered and have pillows around it. I also have to mention that you CANNOT, I repeat, cannot put this material in sun without a cover. I only placed it in the sun for a short couple hours exposed and it turned from white to yellow immediately. But it didn't affect the density of my foam so I didn't return it and I continued to cut it to fit for my van bed. And so, speaking of the firmness of the foam. It's perfect for me. It molds to my body without sinking. It's extremely comfortable. Which is why I overlooked all the other cons to it. It's practically perfect for me and my new vanlife adventures. I had to measure and cut it to size (what you see pictured) since I did a DIY bed/bench. I would have to purchase another one in the near future in order to complete the full bed when it converts. I have a Ford 2019 Transit Connect so my foam fit up to 71 inches. Will buy a second foam soon from this seller. Thank you ?Foam worked well to replace deteriorated foam in chairs that I reupholstered. Chairs are comfortable and the foam completely covered the seat prior to applying fabric for reupholstered chairs. Not quite a memory foam but sufficient and comfortable for my project. Would recommend. Before and After photos show chair on Left before reupholstered and chair on Right after.Overall this is fantastic! Used on our couch to stop sagging, provide comfort, and increase seat height. A family member is sleeping on it due to injury and it was uncomfortable after several days. This foam was PERFECT for our use in EVERY way! It is very sturdy, doesn't go flat even with 24/7 use. Now here is the catch... the description says 6" height, 30" wide, 72" length. Our couch is 68" long from arm to arm. When I unrolled the foam I let it rest/rise/straighten out for about an hour and measured it expecting to cut a few inches off. Good for me in my application that it measured at exactly 68" in length. I report this for others expecting exactly 72"...My old sofa has been revived by using this. Only required a few inches trimming off the end and it fitted just right.With a sheet of thin plywood underneath the foam, a layer of memory foam above it & the whole thing covered with a waterproof canvas material we were able to make really comfortable cushions to fit a window seat.This was bought because it was the exact size I needed and didn't need to be cut. The foam is firm but good quality and provides good support as a second mattress on a thin cabin bed.It wasn't as firm as I expected it to be but it was just as well it wasn't.Upgraded my futon bed from only-if-desperate to that'll-do-nicely.The item received was a horrible patchy yellow colour. You could tell it’s been sat around a while. Luckily my material was dark enough that you couldn’t tell!
