Split Tension Mattresses A split tension mattress is where you can select a different tension for the left and ride side, making them an ideal choice for sleeping partners who prefer different levels of firmness or for differently weighted sleepers. The beauty of split tension mattresses lies in their bespoke handcrafting, meaning you can customise them to exactly your needs. Filled with a blend of natural and manmade fillings, these luxurious mattresses are made with your ideal sleep in mind.
