We have the Ikea Kura in a lofted style as well. He was a few months shy of 4 when we got it (last May). He was never one to get out of bed even in his toddler bed. The last couple months he's gotten to using the ladder and going up and down (he could do it when we got it though). It's a mid-loft, and is nice because I can still reach him in bed. Once we get in a real house versus the little condo I'd love to get a twin over full set. We'll keep this one as a fort for the playroom or something. It's nice now as he has a small room and it gives play area underneath.
