We got this online from target and love it. There were some hassels in putting it together (i.e. they sent screws that were too short, etc) But once it's together it is great. The up and down ladder (rather than the slanted one) saves room. The finish is great. You can get a trundel or drawers underneath (I think).
My little girl slept on it for a couple months and then decided she was afraid because she saw a few spiders on the ceiling and thought they'd get her at night up high. So she hasn't slept on it for months. But she's pretty young and I'm hoping she'll grow back into it:)
