We spend a third of our lives in bed, which is why we understand the importance of a good night's sleep. Perfect recovery begins with choosing a quality mattress for sleeping. The use of Bonell springs in the Olivia mattress with its silver cover makes the mattress springy and prevents it from sagging. An additional layer of felt and molded highly flexible HR foam ensures that we have a mattress that is not only comfortable but also durable. All of this is encased in a removable silver cover.
