Has anyone tried any of the cushion lab products? Are they worth it?

Give me a few minutes and I'll go look. Me ex bought it for my Hank Hill ass...

That’s gonna fuck up your stroke bruh. If you want a seat cushion for a rowing machine a folded towel or a piece of an old yoga mat will do. You can buy more expensive rowing specific seat cushions but it’s lowk not worth it unless you’re spending a serious amount of time on the erg (and are still uncomfortable)
