This weekend I had the pleasure of going home to see my parents, and sleep in my own bed. Lets just say that sleeping on an actually comfortable mattress was a un-awakening experience. (hardy-har-har) My body feels more rested than it has in several weeks, and I have more energy, even coming back to school when I wake up I still feel like I have rested better. At my old job I was a sales manager at a furniture store, so I can honestly say with confidence that your mattress so directly effects your sleep and it can really make a huge impact in how you sleep.
Fun fact of the day, humans spend on average one third of their life in bed, so a good mattress is really an investment, not a luxury.
