I purchased this mattress with the adjustable base for my wife. We had another brand mattress adjustable bed and the mattress was very hot for her and kept her sweating at night. She did all the research on mattresses and knew exactly what she wanted when we got to the store. It's the best sleep ever with the cooling plush mattress. It's so comfortable and the mattress keeps her cool at night. I'm happy she did the research because it is definitely the best mattress we've owned. It was a great choice.The King size Sealy Hybrid is the way to go! We love it
