I can’t believe nobody is actually assisting the OP with a valid question. So allow me.
Your site name seems to indicate you’re a woman, so I assume size matters. So you want an inflatable that’s long, wide, and firm - one that will stay up all night. Some of the Thermarests are known for getting soft before morning unless you want to be blowing during the night, so I’d stay away from those. I’d also stay away from BPL’s swap - you want one that hasn’t been passed around too much. Also, unless you’re one of those who just lay there without moving, you want one that will accommodate a variety of positions. You’ll probably find a good pillow indispensable in this regard. Lastly, shop for the newer models, regardless of what Eric B or Dale W might say. While the older models might be easier to maintain and even be a bit more comfortable, they probably won’t be as firm, or stay as firm for as long. That might be important to you.
Hope these tips help.
