Ergotron Neo-Flex WideView WorkSpace Cart

No, the Ergotron Neo-Flex Mobile MediaCenter VHD Cart will not accommodate the Sony BRAVIA XR A95K 55" 4K HDR Smart QD-OLED TV which uses a 300 x 300 VESA mount. I would recommend the Chief Large Mobile A/V Cart (Black)(BH #CHPFCUB). See: https://www.bhphotovideo.com/c/product/507234-REG/Chief_PF_CUB_PFC_UB_Universal_Flat_Panel_Display.html/specs
