A seating unit, comprising: a backrest; a first foot-support ottoman; a chassis that includes a pair of base plates in substantially parallel-spaced relation each having a lower edge, a forward portion and a rearward portion, and at least one crossbeam spanning the base plates and fixedly attached to the lower edge thereof; a pair of seat-mounting links in substantially parallel-spaced relation, wherein each of the seat-mounting links is disposed in an inclined orientation in relation to the base plates; a seating support surface extending between the seat-mounting links; a pair of generally mirror-image linkage mechanisms each interconnecting each of the base plates and a respective seat-mounting link, and adapted to move between a closed position, an extended position, and a reclined position, wherein each of the linkage mechanisms comprises: a pair of ottoman assemblies that movably inter-couple the first foot-support ottoman to the seat-mounting links; and the backrest having a rearmost edge that defines a wall plane that is perpendicular to the underlying surface when the seating is moved to the extended position and when the seating unit is adjusted to the reclined position the seat mounting links are translated forward and upward in relation to the base plates such that the rearmost edge of the backrest is located forward of the wall plane, characterised in that the seating unit further comprises a pair of roller systems adapted to translate the seat-mounting links over the base plates during adjustment between the closed position, the extended position and the reclined position while maintaining the inclined orientation relationship therebetween such that the seating support surface is biased at a particular inclination angle throughout adjustment. a backrest; a first foot-support ottoman; a chassis that includes a pair of base plates in substantially parallel-spaced relation each having a lower edge, a forward portion and a rearward portion, and at least one crossbeam spanning the base plates and fixedly attached to the lower edge thereof; a pair of seat-mounting links in substantially parallel-spaced relation, wherein each of the seat-mounting links is disposed in an inclined orientation in relation to the base plates; a seating support surface extending between the seat-mounting links; a pair of generally mirror-image linkage mechanisms each interconnecting each of the base plates and a respective seat-mounting link, and adapted to move between a closed position, an extended position, and a reclined position, wherein each of the linkage mechanisms comprises: a pair of ottoman assemblies that movably inter-couple the first foot-support ottoman to the seat-mounting links; and the backrest having a rearmost edge that defines a wall plane that is perpendicular to the underlying surface when the seating is moved to the extended position and when the seating unit is adjusted to the reclined position the seat mounting links are translated forward and upward in relation to the base plates such that the rearmost edge of the backrest is located forward of the wall plane, characterised in that the seating unit further comprises a pair of roller systems adapted to translate the seat-mounting links over the base plates during adjustment between the closed position, the extended position and the reclined position while maintaining the inclined orientation relationship therebetween such that the seating support surface is biased at a particular inclination angle throughout adjustment. a pair of ottoman assemblies that movably inter-couple the first foot-support ottoman to the seat-mounting links; and the backrest having a rearmost edge that defines a wall plane that is perpendicular to the underlying surface when the seating is moved to the extended position and when the seating unit is adjusted to the reclined position the seat mounting links are translated forward and upward in relation to the base plates such that the rearmost edge of the backrest is located forward of the wall plane, characterised in that the seating unit further comprises a pair of roller systems adapted to translate the seat-mounting links over the base plates during adjustment between the closed position, the extended position and the reclined position while maintaining the inclined orientation relationship therebetween such that the seating support surface is biased at a particular inclination angle throughout adjustment.
