Because of a spinal cord injury, I have a lot of pain on my tailbone and am barely able to sit for longer than 30 minutes. I ordered this in the hope that it would bring some comfort, and yes it does what it says!
After using this for about 2 months I can say it has cured my bruised tailbone with flying colors, and it has retained its structure having been sat upon by a large man for the duration.
Since I started using my pillow last week I have not had any pain. It makes my work day much more pleasant and I don't go home at the end of the night with pain.
I spend 40 hours a week in front of my computer for work and another 20 hours for class, I can honestly say that this cushion has become indispensable. The cover material is soft, and the memory foam holds up beautifully. The non-skid base has kept the cushion in place on leather, vinyl, and fabric.
