I received Serta Perfect Sleeper Radiant Rest 14" Hybrid Firm Mattress for free in exchange for my honest reviews. The firm support is perfectly balanced with its smooth comfort. It is soft and firm at the same time. The 14 inch height of the mattress has extra touch of elegance to my bedroom. I can see the attention to detail in the craftsmanship. the hybrid design has a perfect balance of firm support and a plush comfort. 

I like the feature of isolated motion, which means when my husband next to me turns around, I wouldn’t feel it. Well not 100% but much better than any mattress I have ever used. I’ve noticed improvement in the stiffness of my muscle when I wake up every morning. The quality of this product is truly impressive. I would definitely recommend it.
