Abstract: A malleable seat base with differentiated accommodation sectors for protuberant areas applied on seats of furniture destined to the accommodation of seated individuals” represented by an inventive solution in the furniture industry, specifically in furniture destined to the accommodation of individuals in the position technically known as “seated position,” wherein, to solve the problem of discomfort created by protuberances on the individual's clothing (A), notably in pockets (c1) of pants (c1), in the gluteal region, to the seat (b) notably in the structural foam element (b22), at least two relief sectors (b23), also made of foam, are introduced in line with the pockets (c1), wherein, however, their density is lower than the structural foam (b22) density, wherein, alternatively, the relief sectors may be defined in the form of empty spaces, inflatable purses and even a mechanical dampening system.
