Furniture comprising: - sliding doors suitable for sliding along a translation direction (T-T) in which such doors being two or more to gain access to at least one space in the furniture; - a closing mechanism; - said mechanism for closing sliding doors of furniture, comprising: - at least two closing elements, each associated to a respective door, suitable for being fixedly connected to the furniture and with respect to the latter rotatable about a rotation axis (R-R); - a locking body suitable for being fixedly connected to the furniture in which said locking body is associated to the closing element so as to make it rotate by a predetermined amount about its rotation axis (R-R) from a first to a second angular position and vice-versa and so as to be able to lock it in any one of said positions; - said at least one closing element further comprising a locking portion that through the rotation of the closing element can pass from a first position in which such locking portion is suitable for preventing the translation of the sliding doors of the furniture to a second position suitable for allowing the translation of the sliding doors; characterised in that the closing mechanism comprises a synchronisation bar that makes said at least two closing elements rotate as a unit so that the rotation through the locking body of any one of said closing elements determines the simultaneous rotation of all the other closing elements connected through the synchronisation bar ensuring the simultaneous locking in said first closing position or in said second open position of the sliding doors of the furniture. - sliding doors suitable for sliding along a translation direction (T-T) in which such doors being two or more to gain access to at least one space in the furniture; - a closing mechanism; - said mechanism for closing sliding doors of furniture, comprising: - at least two closing elements, each associated to a respective door, suitable for being fixedly connected to the furniture and with respect to the latter rotatable about a rotation axis (R-R); - a locking body suitable for being fixedly connected to the furniture in which said locking body is associated to the closing element so as to make it rotate by a predetermined amount about its rotation axis (R-R) from a first to a second angular position and vice-versa and so as to be able to lock it in any one of said positions; - said at least one closing element further comprising a locking portion that through the rotation of the closing element can pass from a first position in which such locking portion is suitable for preventing the translation of the sliding doors of the furniture to a second position suitable for allowing the translation of the sliding doors; - at least two closing elements, each associated to a respective door, suitable for being fixedly connected to the furniture and with respect to the latter rotatable about a rotation axis (R-R); - a locking body suitable for being fixedly connected to the furniture in which said locking body is associated to the closing element so as to make it rotate by a predetermined amount about its rotation axis (R-R) from a first to a second angular position and vice-versa and so as to be able to lock it in any one of said positions; - said at least one closing element further comprising a locking portion that through the rotation of the closing element can pass from a first position in which such locking portion is suitable for preventing the translation of the sliding doors of the furniture to a second position suitable for allowing the translation of the sliding doors;
