Added to another wayfair purchase of a firm memory foam mattress that was too stiff for my husband, and it gives just enough fluff in between to help with the firmness. I did think it would be more substantial but considering we got the cali king it BARELY fits in our standard size washer and dryer, I guess it's good that it's air fluffy and not substantially fluffy. It's definitely reminiscent of a comforter, which I enjoy, so hopefully my prince and the pea hubby will also like it.
