Hello, my husband and I have a slatted base wooden bed - the slats are about 6 inches wide. The bed is super king sized. I am approx. 8 stone in weight and my husband 13 stone. We do not know what firmness our existing mattress is as we have had it for so long it probably bears no resemblance to it's original make-up! We do know that we are both more comfortable on a more firm mattress - we are probably in the minority in finding Greek self catering beds really comfortable whilst other people consider them rock like. I am getting to that age where being comfortable and cool on an night time will become more important...can you advise which of your ranges and what mattress make-up would suit please?
