Perfect! Purchased to place under seat cover of John Deere lawn mower S110. John Deere makes a great mower but their seat is not so soft! These cushions are super soft and of good quality.

This was a Christmas gift. I use it every day. It really helps on long drives.

Got it more for the racing sim seat as I spend some time sitting down, driving around the track like a scalded bald eagle, singing out the last note of freedom til its heard across the land, raising hell, praising Dale, doin it for Dale with some orthopedic cooling gel memory infused seat cushion comfort and lumbar support. Yeah it's been great for I what I purchased it for!! I typed this from my wife's account too, she don't normally sound like that.Nothing is perfect that's why it's 4, otherwise, excellente purchase!

Like Sitting on a Cloud Made Just for Big GuysI don’t say this lightly—this cushion combo is divine. As a big man who spends long hours at a desk, finding comfort has always felt like chasing a unicorn. But the Everlasting Comfort Lumbar Support & Seat Cushion changed the game. My bunghole? Walking on clouds. That’s right—floating in pure, plush bliss.The seat cushion cradles you like royalty while the lumbar support hits that perfect sweet spot in your lower back. It’s firm yet forgiving, supportive but never stiff. Whether you're working, gaming, or just vibing in your chair, you’ll feel like you’ve unlocked a cheat code for comfort.Highly recommended for anyone built like a linebacker or just tired of that numbing tailbone pressure. This isn’t just a cushion—it’s a throne. You’ll wonder how you ever sat without it.

I got this do to tail bone problems when sitting, the little tail bone spot isn't big enough or something. I still get pressure where I don't want it. Seems well made and otherwise works as designed.

These cushions are extremely comfortable & has helped my sciatica pain! I recommend these 100%!

This is a perfect must have

I bought this to make the regular wooden dining chairs we have at home work for 8 hours per day work from home while we are social distancing for covid. Whereas I couldn't sit on the chair all day without a sore tuchus, this makes it bearable by the end of the day, and at the end of the week. That being said, I am ready to be done sitting on it as soon as I am done working, so it doesn't make a chair suddenly into a 16 hours per day seat.I read other negative reviews which made me worry about purchasing, but all brands seemed to be the same....so here's my own experience relative to them:-- re: "mold" mine had no mold on them. I do think some of the black cover, or lint from it transfers, but I was careful to inspect when I first got them, because I would have returned if I thought it was mold. This was the most concerning to me. For me, it was just lint. They did smell a little funny, but it was chemical smell, not mold, and that is pretty typical for memory foam. I left them outside overnight to air out and all is fine.-- re: too squishy/flattens. A member of my household who weighs 300 pounds sat on this for over an hour and did not experience the cushion overly flattening. Of course it squishes, but it has always sprung back so far, and provided comfortable cushioning. I wouldn't say this is soft, it's quite firm. I do notice that the cushion has different comfort levels on different chairs/styles. Both of my main chairs at home have wooden seats, but on one of them, this cushion set is a lot more comfortable. Go figure! So if you have some options yourself, maybe try that. I actually think a very lightweight person like a teenager might sit on this and not get any squish at all and find it a little bit hard!-- re: chair damage -- it does have small rubbery nubs glued to the bottom side of the cushion. It's helpful so it is not sliding around relative to your hard chair. No marks left on our finished wood chairs.--re: previously opened. My box was not really well taped shut (edges of flaps had a gap) but when I pulled off the tape, the graphics on the box peeled off too, so it would be evident if someone had untaped and re-taped. I think that tape job may come from the factory. So, I can't say for sure that it was 100% not opened before, but it didn't appear to be to my eye, just a bit sloppy on the inital box taping. If it had been opened and returned/resealed, they did a fine job re-packing.--re: cracks or tears after moderate use. I have had for 2 weeks, no problem. Fingers crossed it gets me through the covid shut down. When I was inspecting the foam, I did notice that it looks like there was at least one "fold" in the foam -- like a cold shut - where it was in the mold and formed a bit of a surface that goes into the volume of the foam. That could be a weak point and might be the cause of future tearing, but has held up so far. That may depend on the location and direction of the fold in the material. So - maybe a potential manufacturing issue there.In summary. Pleased with the purchase. It's sufficient for my purposes, I have not personally experienced any of the negative features other people found.
