This bed is right in the middle of firm and soft, rating at a 5 for comfort on our 10-point scale. It has a surface of Body Loft that works to bring moisture away from you and let air flow in, giving you better sleep. Then there's a premium material only found in the higher-end of this hotel collection, the HexCloud Gel Foam, which has geometric cutouts that make it flexible in a way that gives great pressure relief. Serta added a bit more softness with a layer of PillowSoft Aire, then deep contouring with Cool Twist Gel Memory Foam.

At the core of the mattress resss is the 800 continuous support. This support system is made of of uniquely tied coils, only bonded vertically. This helps isolate movement to just one line of coils, ensuring you get a night on uninterrupted sleep.

The Total Edge Foam Encasement on this Grand Chateau is a sturdy foam surrounding the coils, making the edges more supported. This increases the sleeping space because it's comfortable right to the edge.

By giving these mattresses a two-sided design, Serta gives you the option to flip your mattress over every 6-12 months to increase the comfort life of the bed.

The 10 year manufacturers warranty means you can sleep soundly, knowing this mattress was built to last for a decade to come.

The Grand Chateau Plush doesn't miss with its solidly constructed design and luxury comfort. It has traditional features that can be harder to find now, and its medium feel is great for any position you may sleep in.
