I have tried the Kirkeville SPT mattress for about a month now and I am very impressed. The quality and comfort is wonderful.. My last mattress i had was not very comfortable. I was looking for a mattress that would help my husband and i not wake up with tons of aches and pain. This mattress has been a great for him. He hasn't woken up in pain at all. He loves the firmness and comfort of the bed. I personally wish it was a little more plush. One feature i have been impressed with is the temperature regulating. We don't seem to wake up as hot as we use to. Especially, when our kids try to squeeze in bed with us. All in all this is a wonderful mattress and i definitely recommend it.
