IKEA TROTTEN manually adjustable sit/stand desk underframe

This white sit/stand underframe has a manual crank handle. It includes the mounting hardware as shown. Height is adjustable between 70cm and 120cm. I used it with a 120cm x 70cm table top that is not included. It is extendable for 160cm wide table top. Note: one of the 4 screws shown in the close up is seized and cannot be unscrewed so the frame cannot be fully disassembled for transport. It does not impact functionality though. (Original price 250$ + Tax)
