My son loves this bed! I got it in gray. It was a pain to put together (I recommend splurging to have to assembled, if you’re able), but it it otherwise a great bed! The bed, itself, sits just above my waist level (I’m 5’6”). The area underneath is not tall enough for my 5-year-old to stand under, but he doesn’t mind crawling around in there. We made the area underneath the bed a superhero fort, and he thinks it’s the coolest thing! This fits a twin mattress perfectly. I was concerned with my son falling out, but the side rails are high enough to keep him from rolling out. And even if he did fall out, I’m not sure the bed high enough for him to be badly hurt.
