Brooklyn Bedding's Aurora Hybrid Gives a New Meaning to Cooling Mattress: "Brooklyn Bedding’s Aurora Mattress is a mattress worth investing in. When it comes to the design of the mattress, it’s the best of both worlds. It’s a hybrid design, which means that it contains both coils and foam. Basically, you're getting the support that a traditional coil system provides, while also reaping the contouring and comfort benefits that you typically get from foam mattresses."
