Serta's exclusive Bellagio At Home Collection, is as grand as the hotel the mattresses are named after. Each mattress in this collection features Individually wrapped coils that react individually to each person to provide excellent body-hugging conformability, while helping to promote proper back support and alignment. Multiple layers of comfort foam, including Gel Memory Foam, designed to reduce heat build up and promote air flow, allowing you to sleep cooler and longer. These Luxurious mattresses are ready to meet your sleeping needs. This model is a very good choice for a back or side sleeper who like a firmer feel yet still has some softness.
