It's actually almost TOO thick, but still pretty amazing!
Note: I bought this directly from the Purple store, as Amazon is out of these. But I would say it was just about worth it. It's very large though, and thick - like almost 3 inches. But it absolutely cradles your rear very well. This is a great cushion if you are going on a long car ride, or a long haul truck circuit. It's a little tricker to make fit onto chairs, and definitely take the exstra 2 or 3 inches into your chair and desk setups. Fortunately, I have a highly adjustable chair, and an electric sit/stand desk, so it's very easy for me to make these adjustments, but less ergonomic setups might find it difficult to adjust to the added bulk.<br /><br />If I had to do it all over again, I might have gotten the smaller one. I'm happy with my purchase though - if I could, I would have given it 4.5 stars, instead of simply 4.
