We spend a third of our lives in bed, which is why we understand how important a comfortable sleep is. A perfect sleep begins with choosing a good mattress. The use of Bonell springs in the Olivia mattress makes it springy and prevents it from sagging. An additional layer of felt and molded, highly flexible HR foam gives us the assurance that we have a mattress in front of us that is not only comfortable but also durable. All of this is enclosed in a removable cover.
