ZIKEE Gel Seat Cushion with Enhanced Support & Breathability, Extra Large Office Chair Cushion, Sciatica & Back Tailbone Pain Relief, TPE Memory Foam Cushion for Office Chair, Car Seat, Airplane

I liked the style of this cushion and hoped it would work the way I wanted it.It was comfortable at first but then, after sitting on it for about 6 hours (with small breaks) it was getting uncomfortable for me. It was starting to feel hard. It could be just my tender posterior. One thing that did not bother me as most do is the tailbone relief cutout. That worked well and I had no back aches.I did keep trying it for about two days before I had to give up on it. So then I decided to use it in my car. It is good for short term like running my errands to the shores.This ability to use it for the car is why I gave it a four star. I can still recommend it for short term use even with an office chair.

The published size was the same as a shop stool I have that has a hard seat, so I got this to make that stool more tolerable. It works! It would be nice if there was some grippy rubber on the bottom to prevent it from sliding around more, but that's a minor thing.

Nice and comfortable fabric. Fabric covering is removable for cleaning. Cushion is supportive and very comfortable to sit on. It did take a little getting used to and I hope will get more comfortable with use. Design is ergonomic and accommodating and the user guide provided is thoughtful and well written.
