The Lippert Components Somnum Sleeper Series Mattresses are designed to provide comfort and support for commercial truck drivers. The Somnum Discovery mattress is a 10" latex foam mattress constructed with a combination core. It pairs a thick polymer, spring base core, with a natural latex upper core. The Indura Spring polymer base provides all the support and adds a durable, breathable cushioning solution. The 3" natural latex upper core delivers elite cushioning for pressure points such as hips and shoulders, according to the company. The mattress's Euro-top construction comes complete with Somnum's premium soft knit cover, and an extra inch of quilted foam sewn into the cover for added luxury. This mattress is available in multiple sizes.
