Over the years, I have purchased 6 mattresses through Overstock; all of them were memory foam, with my last two mattresses I bought being Comfort Dreams. I needed a new twin mattress and I noticed this 14" mattress was on sale for approximately the same price I had previously paid for an 8" Comfort Dreams bed, so I snatched it up. Previously, the thickest memory foammattressI had bought was 10" and it was very comfortable. But the extra 4" on going to a 14" memory foam mattress makes a big difference. The thickness gives a feeling of tremendous support. It is so comfortable that whenmy son spends the night at a friend's house, I sleep in this 14" bed. My current 10" memory foam queen size mattress still has some use left in it as it is only 4 years old, but I'm tempted to replace it with a queen size version of this 14" Comfort Dreams mattress. The mattress cover that comes with this mattress is very well made out of substantial material that does a great job at protecting the mattress. This mattress has all the quality and comfort of a mattress that costs twice the price. If you want the most support and most stable feeling, do yourself a favor and go with the 14" Comfort Dreams mattress. It is a tremendous value even at the regular retail price. I can't imagine a memory foam mattress being better made or more comfortable than this mattress at any size.
