The restonic range is amazing, this mattress provides proper back support and pressure point relieve! Have a look at the range here and decide for yourself.
Thanks for all of your replies folks ( even mrs overowls ). The reason I have asked is that at the moment we have a sprung mattress with memory foam topper and although I don't suffer with a bad back I do wake up some mornings feeling a bit achy, I was wondering if maybe the mattress was the cause ( mattress about 4 years old now ).
