Solid product! Long assembly but the instructions are clear and I did it by myself. (A second person would’ve been helpful for a few of the steps, but it is doable alone.) I just got it together today so I can’t speak to longevity but this feels solid and the materials are overall good quality. I liked that it came with enough hardware to fill in unused holes (you can set it up with stairs on right or left, the extra hardware lets you fill in extra pre-drilled holes which aesthetically really helps.) My son is 5 and he is super excited for this! The shelves are great to display his favorite toys and he’s been playing in the little “cave” under the bed since I got done with the assembly. Anyway, don’t be intimidated by the 48 pages of instructions, it’s really not that bad and the design is both practical and whimsical!
