Don't let my 4-star review dissuade you, as I've had to reassess prior products that initially I thought were great but then failed me in the long term. These are definitely full and plush, you might want to avoid if you prefer slightly thinner support, especially if you are a side sleeper. But so far I find them comfortable and meeting all of my expectations.
