A system for adjusting the height of a furniture item, the system comprising: a frame structure (120, 130), the frame structure comprising a channel bracket including a vertically positioned track member that extends a particular height, the channel bracket including a front wall and a back wall separated by a first width; a furniture item in communication with the channel bracket of the frame structure through the vertically positioned track member; a height adjustment arm connected to the channel bracket and the furniture item and comprising a channel insert disposed within the channel bracket, the channel insert being configured to slide along a longitudinal length of the channel bracket, wherein the channel insert comprises: a first bearing disposed proximate a first end of the channel insert, the first bearing comprising a diameter that is less than the first width, the first bearing in communication with the front wall of the channel insert; and a second bearing disposed proximate a second end of the channel insert, wherein the first and the second bearing (710, 720) are smaller than the channel bracket and are horizontally offset from each other relative to the channel insert, the second bearing comprising a diameter that is less than the first width, the second bearing in communication with the back wall of the channel insert, and an adjustment guide (200, 400) in communication, through a cable, with both the furniture item and the frame structure, wherein the adjustment guide further comprises: a cable tensioner device (325, 340,350, 400) in communication with the cable, wherein the cable extends from the cable tensioner device to the frame structure, and wherein actuating the cable tensioner device cause the furniture item to change vertical location with respect to the frame structure, and wherein, when the furniture item contacts an item while being lowered by the adjustment guide, the first bearing contacts the back wall and the second bearing contacts the front wall, causing the furniture item to tilt towards the frame structure. a frame structure (120, 130), the frame structure comprising a channel bracket including a vertically positioned track member that extends a particular height, the channel bracket including a front wall and a back wall separated by a first width; a furniture item in communication with the channel bracket of the frame structure through the vertically positioned track member; a height adjustment arm connected to the channel bracket and the furniture item and comprising a channel insert disposed within the channel bracket, the channel insert being configured to slide along a longitudinal length of the channel bracket, wherein the channel insert comprises: a first bearing disposed proximate a first end of the channel insert, the first bearing comprising a diameter that is less than the first width, the first bearing in communication with the front wall of the channel insert; and a second bearing disposed proximate a second end of the channel insert, wherein the first and the second bearing (710, 720) are smaller than the channel bracket and are horizontally offset from each other relative to the channel insert, the second bearing comprising a diameter that is less than the first width, the second bearing in communication with the back wall of the channel insert, and a first bearing disposed proximate a first end of the channel insert, the first bearing comprising a diameter that is less than the first width, the first bearing in communication with the front wall of the channel insert; and a second bearing disposed proximate a second end of the channel insert, wherein the first and the second bearing (710, 720) are smaller than the channel bracket and are horizontally offset from each other relative to the channel insert, the second bearing comprising a diameter that is less than the first width, the second bearing in communication with the back wall of the channel insert, and an adjustment guide (200, 400) in communication, through a cable, with both the furniture item and the frame structure, wherein the adjustment guide further comprises: a cable tensioner device (325, 340,350, 400) in communication with the cable, wherein the cable extends from the cable tensioner device to the frame structure, and wherein actuating the cable tensioner device cause the furniture item to change vertical location with respect to the frame structure, and a cable tensioner device (325, 340,350, 400) in communication with the cable, wherein the cable extends from the cable tensioner device to the frame structure, and wherein actuating the cable tensioner device cause the furniture item to change vertical location with respect to the frame structure, and wherein, when the furniture item contacts an item while being lowered by the adjustment guide, the first bearing contacts the back wall and the second bearing contacts the front wall, causing the furniture item to tilt towards the frame structure.
