THIS  IS SHORT IN HEIGHT AND NO  WHEELS AND THE TRAY WAS TOO LOW, BUT I WAS USING THIS AT FOOT OF QUEEN SIZE ADJUSIBLE  BED, AND I USED THE ADHESIVE PADS WITH CLAMPS AND PUT THOSE UNDER THE FRONT AND BACK OF THE TRAY HEIGHTER THAN IT WAS SURPOSED TO BE, I WANTED THE TRAY ON TOP OF MATTRESS AT END OF BED WORKED GREAT MOST OF THE STAND IS UNDER THE BED SO LOTS OF ROOM TO WALK BEHIND IT
