1. A method for selecting a plurality of mattress modules forming a modular multi-zone mattress having an optimized sleep surface when adjoined, the method comprising the following steps:
a) collecting data related to pressure factors of a mattress user, the pressure factors including a weight and a morphological profile of the mattress user;
b) selecting a number of the mattress modules in accordance with slope variations in the morphological profile;
c) selecting a deformability of each one of the mattress modules resulting in a deformability profile of the sleep surface;
d) determining at least one of a body posture and a contact pressure distribution across the sleep surface based on the deformability profile of the sleep surface and the pressure factors of the mattress user; and
e) determining an optimisation factor based on the at least one of the body posture and the contact pressure distribution,
wherein the steps c), d), and e) are repeated until the deformability profile results in the optimisation factor that provides for the optimized sleep surface when the plurality of selected mattress modules are adjoined, and
wherein the method further comprises juxtaposing in a longitudinal direction the selected mattress modules to produce the optimized sleep surface of the modular multi-zone mattress.
