    Comments about King Koil Heavenly Nights King Mattress:

    We bought this bed in November 2015, hoping to get a year or two out of it.. It's been 9 months and we have the worst sleeps. My husband and I both are average weight, and the bed literally has sunk on each side leaving a hump in the middle... The springs make popping sounds every so often, and we have terrible sleeps. I wasn't expected a world class mattress but this was just a huge waste of money. :(
