My Lush Ultra Plush Mattress set provides the ultimate comfort and quality for those side sleepers! With layers and layers to cater to your desired comfort, you can't go wrong! Fall into the first layer, a cooling cover with innovative threads that regulate your temperature providing the ultimate cooling experience while you sleep. Followed by an anti-microbial safeguard fiber, a convoluted foam for optimal airflow, plush comfort for alleviating pressure, Bob-O-Pedic Gel Memory Foam for temperature regulation and pressure relief, AND a plush foam for even more relief of pressure. All these layers sit atop an individually wrapped spring coil system with firm perimeter coils for ideal body conformity, edge support, and increase sleep surface area. Finished off with a densified fiber base, to provide increased stability and durability. But wait, there's more! With an added level of cloud-like comfort, my Lush features a pillow top layer keeping you cozy all throughout the night! Additionally, this mattress comes with a 20-year non-prorated warranty. All these dreamy features for outstanding value feel too good to be true!
