Good, solid wood structure, relatively easy to assemble. Instructions could be clearer – some smaller details have been left for the buyer to work out. But for anyone with basic DIY skills, very manageable. Also, our step ladder came with slightly warped wood, so that the ladder took a slight helix-like shape – it is still usable but could be straighter. Finally, it would make sense if the ladder would be wide enough to be attached to the vertical post of the bed on the side of the shorter ladder beam – this would provide added support.
