    Only a couple of reviews, not a lot of choices for gel foam in a Cal-King. We have been using about a month. First night we slept on it is was a bit too firm for wife and myself. We used an old 3" topper and made it too soft, so bought a new 2" topper and now it is just right. The mattress itself is fairly firm but sinks in just a little. Since we like a soft bed, with the 2" gel topper it is soft but firm and with the gel stays cool. I would buy again if needed. It has a 180 month replacement which was the best warranty I found. Overall a good deal compared to the high end gel mattresses at $2500.

    We have had the memory foam bed in our semi truck. Put 1 million miles on it So I know the foam is far superior to conventional spring, or air or other foam products. Was anxious to try the GEL. I myself prefer the firmer mattress, my husband prfers the softer. This was a good compromise for both. Not too firm and not too soft. You do have to have a good foundation underneath. My box springs and frame was broke. So for the first night or two took a while to figure out it was not the Mattress. They say the Gel keeps you cooler. We live in WY and it is Winter, so Warm is good for us. Great prduct for the price and extremely love the fact it came right to our home and I had surgury SO my husband put up the king size Mattress himself. Very Easy to handle right out of box.
