Comfortable and well made. Recommended.

The cushion is firmer than similar products I've used but still good enough.

Way too small for adults and not that comfortable either – probably because it is too small.

Comfortable just what I wanted

Working from home I have a fairly comfortable but thinnly padded chair that feels a tad uncomfortable after an hour or so (a shame MightyApe doesn't have facility to include photos in their reviews). This cushion makes a huge difference in comfort for me, so much so that I bought a second as a spare for the day (hopefully in the far future) when this one eventually need replacing. Absolutely worthwhile. Quite a decent size (about 60cm wide by 35 deep) and mesh cover allows airflow.
