Trickonometry Half Moon Extra Firm Pillows - Versatile D Shaped Half Roll Cushion Support and Bolster Pillow for Under Knee, Neck Pillow, Leg Rest, and Tension Relief (White)

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 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.

Very good pillow quite hard and it’s for those who need a hard pillow and it’s memory foam comesback every time I have two of these one is old it just started becoming softer after 2 years so yeah it’s worth it

Wanted a firmer pillow. Mine was getting a little too soft. This one is definitely firm.

This is a wonderful bolster pillow. It feels soft and yet it's nice and firm.

The product is way too hard. I do not recommend it to anyone.
