    A mattress made in heaven!

    Best night sleep ever! Plush and full of support for the usual restless sleeper.  So happy my wife picked this mattress out. I highly recommend it!


    Super comfort and cool at night

    We've had the i Comfort CF4000 for about 10 days and love it. Here in southern Louisiana staying cool at night to sleep is of concern and one of the reasons we waited to get a memory foam mattress. Well you got it right. My wife who always sleeps with socks decided to sleep without them the first night on the new mattress and bed. She woke up complaining her feet were cold. She now sleeps through the night as do I. We both had problems with snoring but the Motion Essentials IV Split King Adjustable Base allowed us to adjust our head height independently and slept silently for the first time in years. This bed is what we needed as I sleep on my side and on my back and always feel support on this mattress. One problem is where can I get the headboard mounts that I need?
