Of course the best position varies from person to person – you can meditate standing, walking, sitting, lying…perhaps some other postures too!
Generally, for sitting meditation, any position that is comfortable for you that allows you to adopt a straight back is good. Generally means having your knees being below the level of your hips, so either sitting with your knees low or sitting on a cushion of some kind to raise the hips
Happy sitting!
