We bought two of these when upsizing for our daughters. Instructions were pretty good and clear so wasn’t too difficult to assemble. The most fiddly part was probable putting the drawers together. The beds are nice and solid and look really nice - the girls love them.
I reduced a star because some of the fabric was pretty dirty and 1-2 of the drawers were a slightly lighter or darker colour than the bed frame - we just put them on a side of the bed you couldn’t see easily.
