Assembly was a NIGHTMARE. The first bed we got the screws didn’t fit and we stripped them before the first panel was assembled. Wayfair sent a full replacement. The holes are not predrilled at the appropriate length for the screws provided. It took 2 adults and a kid 2.5 hours to balance and assemble. Lots of strength required. Do not purchase unless you plan to put some work into it. 

They’re lucky it’s such a cool design. Our kiddo loves the structure. Great height for a 5-yr old. Pictured with an 8-in mattress, so going with a 6-in will give you more of a railing. Once assembled it’s very sturdy (may not ever get it apart).
