A bed is something you have to sleep in every single night but we kept putting off getting a new mattress and I have chronic back pain. Finally, we bought the I Comfort series Serta mattress King size and we are completely satisfied. We keep saying "why didn't we do this sooner". We are comfortable and sleep so much better with uninterrupted sleep which is something I never had before. We also love the extra features and are so happy we choose Serta.
