I've had the mint hybrid cal king mattress now for over a month and a half. It's perfect for me. I'm a side sleeper. I used to have a hybrid Tempur-pedic. I hated it. I sleep great with no tossing or turning. No hip or lower back pain. I almost bought a purple mattress for a grand more. I'm so happy I went with this one. Shipping was fast, set up was fast and easy.
