Nope. Not what I was thinking at all. My son was in his crib until well into age 3. We just lowered the side rail when he was allowed to come and go as he pleased (or put it up when he was to stay in) at 2ish, and at 3ish just took the side of it off entirely. A few pillows on the floor were only ever "needed" once.
My vote is this: toddler beds are a scam. They prey on parents wishes & insecurities to extract cash from them. We technically went from the crib to a bunk (temporary due to traveling - he did great with it btw, the kind that's about 4/5 feet tall and a play space under), but "went" from the crib to a fullsize bed with a twin trundle. It'll last 10+ years (instead of 1), we can both lie on it/ read on it/ build tents/ etc. (toddler beds have weight limits of typically 100lbs... and know... if they bounce on them, that creates a weight of more than 100lbs). The twin trundle on the full size bed also works for sleepovers, or when I want to sleep in his room but not in his bed (also as a temporary "landing pad" in case of rolling out of bed... but it was never needed. And (since we have a small house) when we have houseguests, we just change the sheets and pull the twin in our room and kiddo sleeps with us and the guests take his room.
Twin/ full/ whatever... they LAST. If you're nervous about falling out of bed, you just don't use the frame at first. Put the mattress on the floor. Or buy readily available rails for "real" sized beds. You "kid-i-fy" them up with awesome bedding.
