The New Zealand pine feels and looks good; height clearance below the bed is a good 33in, good for playing, reading; assembly was straightforward with two people, though we had missing hardware. I had to go buy 23screws at the local hardware of approximate size (due to screws not being identical sizing to north America); but as with other reviews, not as solid as could be. I doubt the 400lbs limit. Can handle two smaller kids up there for hanging out, but maybe one older kid, and any adults doubtful, and definitely no rough housing. If there were additional struts between the legs like some other models, perhaps you would achieve that sturdy feeling, but as the ladder is angled for easy climbing, you even have one less leg that other models. For now, it is solid enough I envision years of use for my 5yr old, and will just need to tighten the screws every few months.

Happy we got the low loft model for our younger child, not too high for scary sleep or ladder scenarios.
