Purchased the Luxe in a king with the cool cover. The cool cover got wrinkles in it pretty quickly (about 7 months) and with sheets it doesn’t make much of a difference. Don’t recommend it at all. The mattress performed well until recently. The cool cover is now pilling and can be felt thru our thinner sheets. The mattress itself is bulging at the sides like a pancake. Even with quarterly rotations we are starting to get depressions. I don’t feel it will last more than 5 years which is disappointing.
