Arrived today and as other reviews have stated, it went flat almost immediately. It's boxed up in the front porch waiting for UPS to pick it up for return.

Just horrible, does nothing for posture, not comfortable for long periods of time, and work from home has been painful with this thing. Less painful, yes, but overall still very painful with this.

for a so-called "cushion", this thing is hard as a rock

This cushion compressed down to a 1/2" or less instantly. I had back surgery and needed cushioned support. This has none. Can't return item like you would with a seller that stood behind their products. It is not Memory Foam. Low density cheap foam. Reviewers that only weighed 120 lbs had same problem. I didn't see that before I bought. Could not be more dissapointed.

The cover doesn't stay in one place, but it slids and I have to remove it and rearrange it at least once a week.

The product is very disappointing for an $80+ pillow. Within 2 weeks it has squashed flat and provides no support or comfort. How do I return the pillow? Do you have a product that does provide support and comfort? DHH

I purchased this cushion to help support my back and it quickly went flat, and will not bounce back to how i had received it. It's so flat that I feel like I'm sitting on just a pillow. I'm very disappointed in this purchase. I really wanted it to work for me because I suffer from back pains when sitting at my desk.

You cannot position yourself to make this comfortable. Total, total rip off. horrible horrible horrible horrible horrible horrible horrible horrible

I bought this cushion after reading all the raving reviews though the price was quite steep for just a foam seat. It did held up to the promise for the first week but after that the seat started caving in. I am not a heavy guy but within three weeks this cushion has lost most of its height and is almost a thick sheet of cloth now. Not sure if others were reviewing the same product but I found it a total waste of money.

Hard as a rock and did nothing to help my sore coccyx. In fact, it made the condition worse. Made well but terrible to sit on.
