    Rock hard
  

*by R***. on Reviewed in the United States on September 20, 2024*

If you like extra extra extra firm, this is for you. Nothing like a half moon shaped cardboard... There's memory foam, but it's so firm, it might as well be a baseball bat.Btw, I'm pressing as hard as I can and that's how deep it gets???? Bffr!!!

    I Sit On It
  

*by P***L on Reviewed in the United States on August 24, 2023*

I have sciatica pretty bad and can't sit for long periods on most chairs. This pillow is extremely firm, and when I put it on a chair and sit on it, there's sort of a bicycle seat effect and it takes much of my weight off of the pressure points in my butt. I can sit for long periods again. The manufacturer should advertise it for this use. Regular soft pillows are useless for me to sit on.
