This mattress falls right in the middle of our comfort scale with a rating of 5. The neutral feel is fit for all sleeping positions. The first layer of comfort padding is Body Loft which works to wick away moisture and regulated temperature for a more sound, deep sleep. Next up the HexCloud Gel Foam, which is only found on the highest end models in the hotel collection, has a special design with geometric cutouts that allow you to sink into the foam for outstanding pressure relief. Great pressure relief reduces tossing and turning for restful and restorative REM sleep. Next up, Serta PillowSoft Aire provides and plush comfort and Cool Twist Gel Memory Foam provides further contouring pressure relief as well as reduces motion transfer.

Nestled between the mattresses two surfaces sits the 800 Continuous Support system. This system of connected coils offers stable and consistent support to the whole body. Rather than being connected on all sides, Serta has connected these coils only along the vertical access to minimize motion transfer across the bed for undisturbed sleep.

The impressive Total Edge Foam Encasement is a sturdy border that surrounds the coil system. This edge holds up very well to weight when sitting on the edge of the bed and allows for a greater useable sleeping surface. If you share the bed you can sleep up to the edge and still feel supported.

The unique two sided design means that the comfort layers can be found on either side of the mattress with the coil system in the middle. This feature means that every 6-12 months you can turn the mattress. The foams get time to rest and revitalize resulting in a longer comfort life.

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

You can't go wrong with the solid construction and luxurious comfort of the Grand Chateau Plush. If you are looking for some of those traditional and now hard to find features, like a sturdy continuous coil and two sided design, this is the perfect choice. If you like a medium feel this will be comfortable for back, side, and stomach sleepers.
