Everlasting Comfort Doctor Recommended Memory Foam Seat Cushion for Office Chairs & Car - Ergonomic Office Desk Accessories - Cushions for Tailbone Pain Relief, Sciatica (Onyx, Large)

Great for my office chair I love it and have been using it for months. Plane ride was a recent thing I tried. I tried to do it for a 4 hour flight and it was a no go. Im 5’4” and felt like it made me to tall and misaligned my back to the backseat contour. The seats are also tilted on the plane so when this kept sliding back it just added a lot of pain vs helping. I only tried it once so I dont know if it was that specific airline/user error. TLDR 1000% yes to office chair. Do not recommend for planes.

I bought the Everlasting seat cushion because of its great reviews and the fact that it’s doctor-recommended for back and tailbone support. The cut-out design is smart — it’s meant to relieve pressure on the tailbone, and the memory foam feels high-quality and soft. The cover is also nice and easy to remove for cleaning. That said, it just didn’t work as well for me personally. I was hoping for more noticeable relief for my lower back pain, but after using it for several days, I didn’t feel much difference. Also, the cushion is thicker than I expected, which raised my chair height and made sitting a little awkward. It also slid around more than I liked, so I had to keep adjusting it. Overall, it’s a well-made cushion and probably works great for some people — just not the right fit for my back needs, so I returned it.

As described

Does not seem to be as thick as shown in the illustrations. However it is well made and seems sturdy enough. I use it in a recliner for more comfortable seating.

My husband is a proud over-the-road, long-distance truck driver who often deals with seat discomfort during his long hauls. Wanting to help ease his lower back pain, I took the initiative to research memory foam seat cushions that could provide real comfort and support. After nearly two years of searching and comparing options, I decided on the Upgraded Everlasting Comfort Memory Foam Seat Cushion. What set it apart was its 3-inch thickness—thicker than its 2-inch predecessor and most current competitors. Honestly, I wasn’t sure if he’d actually use it, but to my surprise, he loves it! He’s noticed a significant difference in his comfort level on the road. The only downside is that the cushion seems designed primarily for office chairs—it could use a bit more width and length to better fit vehicle seats. That said, there really isn’t a comparable product out there tailored specifically for truck seats, and this one gets the job done. He’s even started recommending it to his fellow truckers, which says a lot. If you're a driver looking for some relief, this cushion might be worth a try.
