Firmness is as expected, maybe even a little softer than desired but it works for us. Big seats, with plenty of room to sit cross-legged if you want, but also good for both relaxing back or sitting up on the edge. The only negative thing I have to say so far is that one chair arrived with a broken support beam (staple split it) and missing both types of washers. To Wayfair's credit, they promptly replaced this chair, and the replacement had everything and no damaged pieces, but it is ridiculous that the washers and bolts are loose inside the bottom of the chair instead of being contained in a small bag.
