The infant support structure includes a support base to support the infant support structure on a supporting surface. The infant support structure also includes a seat supported by the support base at a distance above the supporting surface, a lift mechanism configured to selectively impart vertical movement to the seat, and a rotation mechanism configured to, independently of the lift mechanism, rotate the seat about a pivot point. The lift mechanism is configured to allow rotational movement to be imparted to the seat while the seat is undergoing vertical movement. ## Claims ### Claim 1 An infant support structure comprising: a support base to support the infant support structure on a supporting surface; a seat supported by the support base at a distance above the supporting surface; a carriage at least partially housed in the support base; a lift mechanism disposed on the carriage and configured to selectively impart vertical movement to the seat; and a rotation mechanism configured to, independently of the lift mechanism, rotate the seat about a pivot point by rotating the carriage, wherein the lift mechanism is configured to allow rotational movement to be imparted to the seat while the seat is undergoing vertical movement. ### Claim 2 (depends on 1) The infant support structure of claim 1, wherein the carriage further comprises: a top portion; and a bottom portion, wherein the bottom portion is fixed in the XY plane and the lift mechanism is configured to impart the vertical movement to the seat by moving the top portion vertically. ### Claim 3 (depends on 1) The infant support structure of claim 1, wherein the carriage includes wheels configured to engage a track included in the support base, such that the carriage is rotatable on the track within the support base. ### Claim 4 (depends on 1) The infant support structure of claim 1, wherein the support base further comprises: a housing including an interior cavity; and legs extending downwards from the housing, wherein the legs support the infant support structure on the supporting surface. ### Claim 5 (depends on 4) The infant support structure of claim 4, wherein the rotation mechanism is disposed within the interior cavity and the lift mechanism is configured to extend upwards out of the interior cavity. ### Claim 6 (depends on 1) The infant support structure of claim 1, further comprising: a vibration mechanism configured to impart vibrational movement to the seat. ### Claim 7 (depends on 6) The infant support structure of claim 6, wherein the vibration mechanism, the lift mechanism, and the rotation mechanism are each powered by the same power source. ### Claim 8 An infant support structure comprising: a support base to support the infant support structure on a supporting surface; a seat supported by the support base at a distance above the supporting surface; a lift mechanism configured to selectively impart vertical movement to the seat; and a rotation mechanism configured to, independently of the lift mechanism, rotate the seat about a pivot point disposed within a lateral periphery of the seat, wherein the lift mechanism is configured to allow rotational movement to be imparted to the seat while the seat is undergoing vertical movement. ### Claim 9 (depends on 1) The infant support structure of claim 1, wherein the seat is mounted atop of the carriage. ### Claim 10 An infant support structure comprising: a support base to support the infant support structure on a supporting surface, the support base including a housing and a carriage operable to rotate relative to the housing, the carriage including a bottom portion and a top portion; a movement mechanism including a lift mechanism configured to vertically move the top portion relative to the bottom portion and a rotation mechanism configured to, independently of the lift mechanism, rotate the carriage relative to the housing; and a seat coupled to the carriage and configured to receive an infant. ### Claim 11 (depends on 10) The infant support structure of claim 10, wherein the rotation mechanism rotates the carriage about a pivot point disposed within a lateral periphery of the seat. ### Claim 12 (depends on 10) The infant support structure of claim 10, wherein the seat is coupled to the carriage atop the top portion of the carriage. ### Claim 13 (depends on 12) The infant support structure of claim 12, wherein the seat is coupled to the top portion of the carriage via a recline mechanism that allows the seat to be repositioned between an upright seating configuration and a reclined seating configuration. ### Claim 14 (depends on 10) The infant support structure of claim 10, wherein the movement mechanism further comprises: a vibration mechanism disposed in the top portion of the carriage. ### Claim 15 An infant support structure comprising: a support base including a housing and a carriage disposed at least partially within the housing; a seat configured to receive an infant in a reclined or upright position, and a lift mechanism disposed on the carriage and configured to move a first portion of the carriage with respect to a second portion of the carriage in order to impart vertical movement to the seat, wherein the seat is mounted atop of the carriage and the carriage is configured to independently impart both rotational movement and vertical movement to the seat. ### Claim 16 (depends on 15) The infant support structure of claim 15, further comprising: a rotation mechanism configured to impart the rotational movement to the seat via the carriage. ### Claim 17 (depends on 16) The infant support structure of claim 16, wherein the rotation mechanism is disposed in the housing and rotates the carriage about a fixed point disposed within a lateral periphery of the seat. ### Claim 18 (depends on 16) The infant support structure of claim 16, further comprising: a vibration mechanism configured to impart vibrational movement to the seat.
