Obsessed with this bunk!!! It didn’t take too long for my husband to put it together, maybe 1.5 hrs. It’s sturdy you can tell it will stand the test of time my 4 year old son will put it through. The stairs are great for him to get up and down safely and love that they can be used for either side of the bed. Also love that the top bunk is still low enough for me to tuck him in for bed (I’m 5’3). Worth every penny and when it’s back in stock RUN to get it! I’d recommend building it and giving a full day to air out that warehouse smell.
