The Serta Perfect Sleeper Oasis 14.5 inch firm pillow top mattress was absolutely named correctly. It really does give me the perfect nights sleep!  I've found as I get older I need a firmer mattress and this one is the perfect amount of firmness for me. It helps with my back aches and joint soreness. I wake up feeling refreshed and i realized I don't grunt and groan when getting out of bed in the morning. I actually can enjoy relaxing a bit longer in bed on Saturday morning watching my favorite show and drinking my coffee instead of having to get right up because my back is hurting. Definitely recommend!!
