LIFEMENT Basic 6 Inch Twin Memory Foam Mattress in a Box, Medium Firm | Graphite Infused Cooling, Fiberglass Free, CertiPUR-US Certified

The LIFEMENT Basic Memory Foam Mattress — Smarter Sleep, Night After Night Getting quality sleep should not require spending a fortune. The LIFEMENT Basic Memory Foam Mattress delivers the pressure-relieving comfort of premium memory foam with the safety features and certified materials that every home deserves — all at an accessible price point that does not compromise where it matters most. Graphite-Infused Cooling Technology Traditional memory foam traps body heat, leaving sleepers hot and uncomfortable. The LIFEMENT Basic solves this with a graphite-infused top layer. Graphite particles are naturally thermally conductive — they pull heat away from the body and distribute it across the mattress surface, preventing the heat buildup that wakes you up in the middle of the night. The result is a cooler, drier, and more comfortable sleeping environment from the first night. Three-Layer Construction Engineered for Support Every inch of the LIFEMENT Basic mattress is engineered with a purpose: Top layer (graphite memory foam) — Contours precisely to the curves of your body, relieving pressure points at the shoulders, hips, and lower back. Open-cell construction enhances airflow within the foam itself, adding another layer of breathability. Middle transition layer — Bridges the gap between the soft comfort layer and the firmer base, absorbing motion and preventing it from transferring across the mattress. Partners, pets, and restless sleepers will not disturb each other. Base support layer (high-density foam) — Provides the foundational stability that keeps the mattress from sagging over time. The higher foam density ensures this mattress holds its shape and support for years of use. Medium-Firm Feel for All Sleep Positions At a medium-firm comfort level (6 out of 10 on the firmness scale), the LIFEMENT Basic strikes the balance that accommodates the widest range of sleepers. Back sleepers get the spinal alignment support they need. Side sleepers get enough give to relieve hip and shoulder pressure. Stomach sleepers get the firmer surface that keeps the midsection from sinking. Whether you sleep alone or share a bed, this mattress adapts without compromise. Fiberglass-Free and Certified Safe Some mattresses use fiberglass as a fire barrier hidden inside the cover — a practice that can result in harmful fiber contamination if the cover is ever removed or damaged. The LIFEMENT Basic uses no fiberglass anywhere in its construction. All materials meet the stringent standards of two independent certification programs: CertiPUR-US, which verifies that the foam is made without ozone depleters, formaldehyde, heavy metals, or harmful flame retardants, and OEKO-TEX Standard 100, which certifies that every component of the finished product has been tested for harmful substances. You can sleep with complete confidence. Mattress-in-a-Box Convenience The LIFEMENT Basic ships compressed and vacuum-sealed in a compact box designed to navigate staircases, narrow hallways, and apartment doorways with ease. Setup could not be simpler: remove the box, position the mattress on your base, cut away the packaging film, and allow 24 to 72 hours for the mattress to fully expand and off-gas before sleeping on it. No assembly tools, no white-glove delivery coordination, and no awkward maneuvering of a full-size mattress. Compatible With Most Bed Frames and Bases The LIFEMENT Basic works with virtually any foundation: platform beds, box springs, slatted bases (slats no more than 3 inches apart), and adjustable bases. It does not require a box spring to perform correctly, making it ideal for platform frames and floor placement. Suited for master bedrooms, guest rooms, bunk beds, daybeds, trundle beds, college dorms, and first-apartment setups.
