    Great pad, but perhaps a little too firm for me
  

*by B***M on Reviewed in the United States on July 22, 2020*

I've used a Tush Cush off and on for years, due to a back problem. They're absolutely fantastic. When my husband started working from home so many hours, due to the pandemic, his home office chair just didn't cut it, and set his back problems off. (Well, excessive yard work didn't help either.) I got him this extra firm extra large Tush Cush, but it was actually just a bit too firm. He's almost six feet tall and weighs about 300, so I thought firmer would be better, but no such luck.  I think next time, I will buy him the standard cushion.As the mom of kiddos with autism, there are causes near and dear to my heart. Let Amazon donate to your favorite charity!

    Could be thicker, but works quite well
  

*by G***I on Reviewed in the United States on June 4, 2020*

My first one was either stolen or lost in the mail, so it took a bit to actually get a replacement. I'm satisfied enough that I like it. Working from home has made me have to sit a lot more, and my rather large backside couldn't handle much more without some sort of support. I double it up with a Purple brand seat cushion, and together they're ideal. One or the other just wasnt enough for me.

### ⭐⭐⭐⭐⭐ 







  
  
    Very comfortable with support
  

*by C***E on Reviewed in the United States on October 5, 2018*

It says it "Extra Firm" and it is compared to other seat cushions I've used. It isn't what I would call "hard" though. It's comfortable for me through an 8 hour shift as a 210 lbs guy with a bony butt. The cutout in the back is nice for the handle and seems to be designed to give a space for your butt bone, but that does make the back slightly less supportive. Still, it does raise me up a bit, tilt me forward a bit, and is still comfortable. The best seat cushion I've used!
