sentarse / estar sentado, a
me siento / se sienta (él, usted, ella) / se sientan (ellos, ustedes, ellas) / te sientas / nos sentamos / os sentáis.
*Also "tomar asiento" is possible along with the respective conjugations.
If you're describing the action in action, in this case, use: ir a + sentarse: me voy/ se va / se van / nos vamos / te vas / os vais a sentar.
'sentado' if the action is complete, and you mean 'being (already) seated'
But in the sentence, for instance: "He is sitting down" in Spanish would be: "Está sentado", not "está sentándose". If in English it is described an action being carried out, as with this example, in Spanish it's expressed as a near future: "se va a sentar". It's not common (if not impossible) to say "está sentándose", because the gerund in Spanish is used to talk about an action being carried out for long time: "está lloviendo, está nevando, está haciendo mucho frío". Nevertheless, when you sit down, you don't take long time, not in Spanish. ;)
