    Serta iComfort Foam Mattress

    Wonderful! Not too hard and not too soft. I bought a foam mattress off Amazon but it was too firm. This one is pricier but perfect -- I am a side sleeper and it's soft enough for me to sleep on my side, but still firm enough to support me. I put an extra mattress pad on top and it's perfect. I highly recommend the iComfort. I have the LE edition and I got it on sale for a great price.


    Do not buy an iComfort mattress!!!!

    I don’t care what the salesman tells you, this mattress has not lived up to its promise, and it starts sinking in the first 6 months. Our backs and necks hurt. We have rotated it, tried different settings on the adjustable base, tried different pillows. The integrity becomes compromised and sinks in where you lay. It’s no longer supportive, but it bounces back when no pressure is applied, so they won’t cover it under warranty. It absolutely does not keep you in proper sleeping position when you lay on it. Worst purchase ever, and we’re still paying on it. Buyer beware before you make this much of an investment.


    Very comfortable mattress

    This mattress is wonderful! We originally got it for our guests, but once my husband and I tried it out we knew we will need to get one for ourselves. It is the perfect compromise for us, even though we have different needs and wants in a mattress. The CF1000 Medium is extremely comfortable and supportive without being too soft, and appears very well made. We are hopeful this will last a long time! Thank you, Serta!


    Just wonderful

    wonderful mattress! We are thrilled to offer this mattress in our short term rental!


    Does not compare to our previous icomfort at all.

    We sold our house furnished so of course I wanted another icomfort. We loved our previous mattress, it was like getting into a new bed every night and after 6 years it was still perfect. The new icomfort is horrible, feels lumpy, the edges lack support so if close to the edge it feels like you’ll fall off, terrible on pressure points. I wake up with hip pain everyday. After 17 nights of poor sleep were replacing the CF1000 medium. Unfortunately bought at a furniture store with no return policy. Makes no sense, if Serta accepts returns it should also accept from a furniture store.
