We are impressed with the quality of the Restava mattress. We purchased the Ivory Gel in the king size along with the box foundation. The mattress was described as comparable to the Tempurpedic-Cloud Luxe. I did go to our local Tempurpedic store and test the Cloud Luxe. We are finding the Ivory Get a bit firmer (almost too hard) than the Tempurpedic-Cloud Luxe. I have noticed the mattress seems to be softening somewhat since we first slept on it a month ago. We will give it the full 120 day trial. If it remains too firm we will exchange it for a softer Restava since we are so pleased with the quality of the product. A side note... The box foundation is 9 1/2 inches and when we placed the foundation and mattress in our bed frame (which is a little higher than normal) our bed is too high off the floor. Comfort Selected 4 since the mattress is much firmer than we expected. Support Very firm with excellent support. Firmness A little too firm. Durability We have only been sleeping on the mattress for a month and so far it is very durable. The edge of the mattress is supportive when we sit on the edge of the bed.
