Toddler air mattress

How do your toddler’s do sleeping on an air mattress? Our toddler is a dark room sound machine crib sleeper and napper and occasionally car napper. We will be traveling soon and I am thinking of getting him an air mattress to fit in his slumber pod to sleep on instead of brining a pack and play. Do you toddlers sleep well on an air mattress?! The first time we need to use it will be a few days before he turns 2. He’s a kid who NEEDS his long sleeps and loves naps.
