      What the Sleep Expert thinks...

      "The individually pocketed springs provide targeted support where your body needs it most, while the double-sided design with turning handles is a practical feature that adds longevity. When customers ask me which mattress offers exceptional orthopaedic support with temperature regulation, this is the one I recommend without hesitation."

      Very comfortable and great that you can turn it round and over to keep the shape for longer

      All 3 beds in our home now have these mattresses. The first was on the double. Bed in the spare bedroom. Everyone (we have cat sitters every time we go away + plus relatives) who has slept in that bed commented on what a comfortable nights sleep they had. My wife and I tried it out for ourselves one night and agreed the mattress was very comfortable. So we recently bought 2 king size mattresses for the 2 downstairs bedrooms.
