My Bob-O-Pedic Gem Hybrid Mattress Set is a rare gem, and that's exactly how it got its name! How many mattresses contain top-quality materials, provide numerous sleep benefits AND start at one great low price? This mattress appeal begins right in the top layer with the quilted knit cover. Its purpose is to offer a breathable sleep surface to keep you comfortable. Then there's a layer of Bob-O-Pedic Gel Memory Foam for temperature regulation and pressure relief- which also happens to be my favorite part! Finally, an individually wrapped coil system for conformance and support sits on top a layer of base foam that adds long term support and durability. Plus how can you go wrong with a sturdy foundation to pair it with?
