It works well for what I wanted, just a little padding and keeps you on the seat a bit better than seat alone. It is not like a cushioned bike seat if that's what you want. As far as the adhesive many people complain about, it's works fine as long as you clean the seat with alcohol first. I used a heat gun/hair dryer to warm and dry it after cleaning with alcohol, it has not budged in over a year.

Unnecessary, less comfortable than the seat by itself

Just got this and installed it not very happy with it all all rogue is none for quality so let’s work on making a better product before we start charging ppl for it.

The adhesive and the Concept 2 RowErg seat material aren’t compatible.

This cushion is thin and does not provide much cushion. It also does not stick to the seat well.

Fits great, no problems mounting, and stays put! Life saver for long rows.

Problem with this padding is that it does not stick to the seat. The adhesive on the bottom of the cushion is not tacky enough. After first use the adhesive did not keep the pad in place.

No, it does not stick to the seat. But I used a spray bottle glue, and it worked out. One tip: I "warped" the flat foam pad a little, to fit the curved seat better.
