Enjoy great sleep every night with this gel memory foam mattress. This king-size memory foam mattress is 11 inches thick, and quilted with a top layer of gel-infused memory foam that ventilates the fabric to reduce heat. The next layer is made of cool blue memory foam to cool your body while you sleep. The final layer of this mattress provides support and balance.

The Christopher Knight Home 11-inch Flow Collection contains our Gel-Infused memory foam giving a soothing and refreshing feel. The top and side cover is quilted with 1-inch Gel-Infused Memory Foam with an art auto-wicking mesh border with a specialty designed macro and micro ventilating flow fabric to reduce the heat to avoid discomfort. The next layer is constructed of 2-inch of Cool Blue Memory Foam that gives your body extra cooling sensation while you sleep. Another great feature of this mattress is a 2-inch of High Density Pressure Relieving Foam which serves as the support layer that has a long lasting durability. Finally a 6-inch High Density Reflexive Lumbar Base Layer is provided for superior support and balance to your every move. The bottom cover is made in Anti-Slip removable zipper.

    I have Ankylosing Spondalitis, degenerative discs, and fibromyalgia. I bought an expensive Beauty Rest Recharge which was uncomfortable to me, and I am stuck paying for it. Out of desperation, I found this mattress and ordered it. I was skeptical because I once had a memory foam topper that I did not like. This bed has been a God send. I didn't know it was possible to get this good of a nights sleep. First night was a little hard, but have slept in heaven ever since. Granted, you either like memory foam or not. If you do... this mattress is a great buy. Its very high quaility. You can tell al to of design went into it. The cover is really nice like the high end brands. I would say this mattress has some give and would classify it as a medium firm. Who knew I would have a Peter Brady mattress one day... but I love it.

  • New Memory Foam Bed

    We received the bed in great time and pretty good condition. The box was a little messed up but the bed was well sealed. It is heavy and took some strength and room to get it up the stairs. It takes a little room and a couple of days to unroll so that you can sleep on it. It sleeps well but is a little on the firm side. It is better than my old spring mattress with a 3 inch memory foam topper. About anything would have been since the mattress was ten years old and a spring was poking my back. That is the nice thing a bout memory foam and the cool gel layer is a nice feature, but I don't notice too much difference in temp.

    This mattress has made an amazing difference for my sleep with my back aches. I previously had a memory foam topper that was almost too soft. This has been a perfect mattress for both the softness needed from the memory foam and firmness I did not expect. It also came with a very well made cover that has held up well to washing and also protecting the mattress.

    Shipping was fast, but a corner was dragged and resulted in a corner of the cover being dirty and slightly torn. Not sure if it was the shipping company or if it happened while packing. The mattress itself is reasonably comfortable. Slightly firm but conforms to your body where needed. Sitting up in bed is sometimes a pain because your body starts to sink from the weight. It also retains heat, definitely not cooling. Great for cold bodied persons or during the winter months.

    Very Disappointed in this Mattress. It's longer than the King Box spring and King Frame😠 After 2 weeks you can see exactly where we sleep. Glad I didn't pay the so called $**** original price!!

    "Why did you choose this product?"

    • A:

      Great price and saw comment from another buyer who has fibromyalgia as i do too. Hope i will sleep better!

    • A:

      I left the first review and since it was a new product at the time with no reviews, I chose it because I read reviews of other Christphor Knight mattresses and researching the different combinations of support layers that various similar gel mattresses use. I concluded this combination of support layers would probably be the best for me. It's been absolutey great.

    • A:

      A friend had this mattress, I slept on it for a few nights and liked it.

    • A:

      It had good reviews and I have been looking for a mattress with these qualities at this price.
