Hi, I am looking for a new superking size mattress to go on slatted base. I have tried the Simba mattress at a friends house but after a few days found that it does not give me enough support to my lower back where I have a disc problem. The mattress also seemed very hot. I have also tried the Classicpedic Pocket Memory Mattress from the Memory foam warehouse which we have in one of our spare rooms but found this just slightly too firm - it has 8cm dual HD memory foam layer, 60kg memory foam density, 5 star physio rating, 1500 pocket springs, Medical grade support base for optimum support. We currently have a memory foam mattress which on the original invoice says it's 160mm 270F reflex foam, 40mm V60 memory foam and find this comfortable but needs to be changed as its ten years old. We are of average height 5'6" and 6' 1" and average build in our 40s and both of us have disc problems (neck and back) from sport injuries. Please can you recommend which of your mattresses you think would be best for us and if you have showroom ? Many thanks Liz
