LUCID by LinenSpa 10 Memory Foam Firm Viscoelastic Mattress 20-Year Warranty for $299.99

This is pure luxury at a price that makes sense. The 10" thick mattress features 2.5" of 3.0 lb plush memory foam and a 7.5" polyurethane supportive foam base. The open cell technology allows air flow, keeping you cool and comfortable while you sleep. Open cell construction yields a longer lasting, more resilient foam that will not leave long-lasting body impressions.
